Lightweight concrete refers to an alternative concrete made up of coarse lightweight aggregate and sometimes even portion of finer aggregates. Lightweight concrete is different than regular concrete in terms of density, weight, strength etc. Many PEB structure in Gujarat and other areas have been made with the use of lightweight concrete.
Broadly there are three different types of lightweight concrete:
- Lightweight aggregate concrete
- Foamed concrete
- Autoclaved aerated concrete
Of these foamed lightweight concrete is a low density highly workable concrete with is ideal to fill out redundant spaces/ voids in buildings etc. Because of its high thermal insulation ability it is also good to fill under floor voids. It can also be used to insulate the roofs by filling it in the gaps between roofing sheet in Gujarat/ any construction project.
Autoclaved aerated concrete is another highly thermal concrete base which is used in interior as well as exteriors of construction projects. This is low in density and can be easily cut, routed and/ or sanded. They are fine to be used in construction of solar structure in Gujarat/ India; however they are majorly used in masonry units.
Now for the lightweight aggregate (LWA) concrete! The use of lightweight concrete initially began with it being a load bearing component in the inner cavity of walls. But with time we are currently able to produce and use high strength lightweight concrete which is suitable for most structural work. Many producers of lightweight concrete panels in Gujarat etc will vouch by the fact that in many instances it is equivalent in strength to normal weight concrete.
Even within the segment of lightweight aggregate concrete there are many different types. These include the following:
- Foam Slag:
- Clays and Shales
- Sintered Pulverised
There are multiple benefits to using LWA in place of regular full density concrete. Some of the most prominent benefits of LWA are as follows:
- LWA is optimal when there is need to reduce the weight of the structure in question. Since it comes is great strength but is lighter in weight it greatly helps in reducing the dead loads of the building.
- Another great characteristic of lightweight aggregate concrete is that it is highly thermal. This property also adds to the advantages of using it in place of regular concrete. It improves the thermal insulation of the structure without adding to the weight.
- It is also more fire resistant in comparison and hence is a better option.
- Developers/ builders may favor the use of LWA also because handling precast units of LWA in comparison to regular concrete is cheaper. Also it is cheaper and more easy to transport this type of concrete/ concrete panels.
On site construction is the traditional way of constructing a building, wherein workers and raw material are collected at the site of the building. The workers slowly use the raw materials and give shape to the building.
Prefabricated construction on the other hand refers to when parts of the building/ structure are manufactured in a plant, away from actual building site. These parts are then assembled on site to form the required structure. While traditional construction methods have been the base of Indian construction industry for long, prefabrication is becoming increasingly popular. Many prefabricated buildings in Gujarat and other parts of the nation can be seen taking shape.
Here is a comparative analysis of both these construction methods to access their pros and cons:
One important point of comparison is transportation. In prefabricated buildings there is a need to transport prebuilt parts from the building plant to the actual site of the building. This implies that the size of the pre-constructed parts has to be limited according to the ease of transportation. This requirement is however absent n case of onsite construction projects. Many labor colonies manufacturer in Gujarat/ India are however opting for prefab structures.
Weather is an important environmental aspect to consider when beginning a construction project. Onsite constructions are affected by weather which may cause delays and also affect the quality of construction. Prefab construction on the other hand is not bound by weather changes as it is done behind closed walls of a plant. One great example of prefab structures is porta cabins in Gujarat.
Another important point of comparison between the two construction types is the cost involved in them. There are many ways in which onsite construction is much more expensive than prefabricated construction. For example, prefabrication uses low costing materials such as PUF insulated panels in Gujarat, that drive the cost down.
Since the construction plant for prefabricated construction is closed and bounded, it offers a more secure environment to the workers. Better working conditions in comparison to on site construction, has rendered prefab building a preferred method wherever possible. Portable site office cabin in Gujarat are being built with the use of prefabrication method.
There are two side of this factor. One is that in case of onsite construction, the builder/ owner has the option to alter the plan as and when needed after looking at present progress. But in case of prefabrication this is not possible. In this way prefabrication might be a tad bit inconvenient for those who can’t commit to the design in advance. The second side is that prefabrication helps builder skip the hassles of onsite construction.
With the need for low cost housing in Gujarat and all parts of the nation, prefabricated construction is a rising trend. While both the construction processes have their own set of pros and cons, there are many instances where prefabrication is a preferred method. There is no denying that builders and developer are opting for prefabrication in construction industry wherever and whenever possible.
Many different materials are used in a construction project. All these materials have different types of classifications, uses, benefits and factors to consider when using them. One such important material that forms an integral part of construction projects is I beams. Here we will discuss all there is to know about this product.
What Are I-Beams?
To begin with they are also known as H-beams, W-beam, wide beam, a rolled steel joist and also a universal beam. These beams are made up of two horizontal components i.e. ‘flanges’ which are connected by a vertical component known as the ‘web’. The thickness and strength of these flanges and the web determine the strength of the beam itself.
Type And Factors To Consider When Picking One
All building types including prefab buildings make use of this construction component to make a solid and sound building. These beams are classified into different types on the basis of sizes, section depths, weights, web thickness etc. There are standardized charts which allow builders to access which type/ size/ weight of I-beam to select for a certain kind of weight.
However there are many factors that must be taken into account before a builder/ porta cabin manufacturer settles on a particular size. And these include:
- Vibrations: The beams need to be of certain stiffness and mass to eliminate any kind of vibrations in the building.
- Deflection: Another thing to consider when selecting the right beam size is deformation. The beam should be thick enough to withstand the building weight without deforming.
- Buckling Under Tension: Web thickness and flanges are both required to be in appropriate proportion to avoid any buckling or rippling under the tension.
- Bending: To avoid buckling, the beams must be accommodating of yield stress by bending under pressure.
All builders, developers, manufacturers and even suppliers like container manufacturers will agree that structural integrity is extremely important. And these beams, irrespective of the material they are made of do the job of providing load baring and structural strength to the building at hand.
They form one of the best support pillars for any structure as they can withstand different types of shear and load stresses. Another important component of a building is the different types of purlins or specifically the c purlins.
These purlins are horizontal running components which are meant to support the roof/ roofing sheets of the building. In fact, some builders also replace purlins with I-beams when it suits their needs and requirements.
Since I beams are such a critical part of various constructions and buildings, they are designed by qualified individuals. They are fabricated keeping in mind the need for reliability, strength and stability when it comes to building/ constructions. The ‘I’ shape of these beams translates in the fact that they are really great for the unidirectional bending pressures that are parallel to the beam’s web.
The name universal beam (UB) comes from the fact that these I beams are very versatile and can be used for many purposes. That is, from providing support in erection of a building, to floor support and even support the roofs (color coated roofing sheet etc.) and more.
What are I beam panels?
I beam panels is also called universal beam and are rolled steel joint used for the structural steel building. Its unique design and structure are important for handling a lot of weight. It provides strength and support to the structure of the building.
I Beam Manufacturers in India
I beam panels are widely used in India for construction purpose. There are many I beam manufacturers in India who deal with I beam such as- MS Beams, Eagle Steels Rolling Mills, Jain Steel Industries, Mahavir steels, and so on.
Lightweight Panels and its Advantages
Lightweight exterior wall panels are an achievement of the construction technology. They are lightweight building material for walls which are quite durable just like traditional walls and at the same time light as well. They are made of polymers and polystyrene aggregates which makes them light.
Despite being lightweight, they have all the strength. It can be used for many purposes such as partitions in offices, for making cabinets and even in furniture.
EPS wall panel is a lightweight material to build walls. It has many benefits such as it is fireproof and does not radiate toxic gasses. It also saves on the space compared to traditional blocks.
Sound insulation and waterproof is another advantage of EPS wall panels. So overall it is highly efficient and simple to construct. The wall material provides protection from external environmental factors and possesses heat insulation material as well.
Prefabricated Concrete Walls are durable, flexible, and provides an excellent solution for floors, walls, and roofs for offices. The life cycle of these walls are quite high (upto 100 years) and can be easily relocated and reused.
The speed for constructing them is high and is also weather-proof. The strength and structure of the walls can meet different design standards and plumbing and electrical things can be easily incorporated into them.
Construction site office requirements
It needs a lot of planning and a checklist while setting up the office. From fire safety equipment to welfare supplies, you need to keep a check on everything. So what are the construction site office requirements that you should check beforehand, let’s take a look.
Paperwork- it is very important that you carry all the important documents with you along with necessary paperwork. Essential signatures, health and safety documents, accident books are some of them.
Welfare Supplies- Supplies are important for proper functioning and basic comfort. Cleaning equipment, drinks are some of the things to ensure about.
Fire Safety- It is important to take precaution, especially about fire safety. A fire extinguisher is a must and fire blankets as well. A proper fire safety plan should also be planned in advance. Cost saving fire alarm should also be used.
First Aid Kits- You are never aware of the uncertainties that can take place near a construction site. It is better to keep a first aid kit handy with essential supplies.
Heating or Cooling Supplies- Weather is unforgiving so it is better to make necessary arrangements like fans, coolers etc for comfortable working conditions.
The roof of these houses are built using purlins which are horizontal structural members in roofs; these are supported by rafters or walls. There are two types of purlins – C purlins and Z purlins. Like Beams, C purlins are C shaped sections and Z purlins are Z shaped sections which are used to support standing seam roof systems.
Building a prefabricated office structure is also trending these days, the portacabins and container offices are convenient to assemble and are constructed in lesser time than conventional offices. These container offices are also called liftable cabins and give you a ready to move solution for all your construction needs. These provide modern design; they are weather resistant and durable. There are many container office manufacturers in India.
Advantages of Prefab Structures
Another best thing about these prefab structures is that they are earthquake resistant and need little maintenance. The futures looks promising for prefab homes owing to their convenience in the building, independent of external conditions, comfort for the owners, the potential for customisation and a lot of other positives which stand in their favour. Another advantage is that they are eco-friendly, sustainable and green.As a result, the consumer can save enormous costs on bills as well. Space wise, these homes can be built in the desired way, they can be constructed in areas as minimal as 100 square feet and can go upto 3000 square feet and more.
Prefabricated is becoming the new age choice, the modern preference for the simple reason of their convenience and cost.
Often referred to as Pre-fab Homes, these are modern houses which are built in components and modules. The parts are made off-site and usually assembled on the site in contrast to the traditional homes which are formed on site. These are generally lower in costs and convenient to build or instead assemble.
They are 10% to 20% cheaper than traditional houses and take lesser time for construction. Some of the materials which are used to build these houses are aluminum, fiberglass, steel, wood and concrete. These houses are made of good design high-performance manufacturing units which are moulded and shaped in a controlled environment.
How are prefabricated houses made?
Prefabricated houses are often made in two stages:
- Manufacture of parts at a factory
- Transportation of components and fixing them at the required locations.
Precast Concrete wall panels – The components which are used are precast lightweight concrete wall panels, these are lightweight and these units are casted and hardened before they are being used at the construction sites. Usually, the erection of structures happens easily and quickly if the above technique and process are followed.
PUF Panels – The PUF panels are another essential component of prefab homes; these provide perfect alignment of all panels such as ceiling floors, walls and corner panels. They can be customized to requirements in sizes and dimensions. There are many manufacturers of PUF panels around the country.
H Beams – H-Beams is another essential component in prefab homes; these are H shaped hot steel beams which are fitted to retain and pile structures one over the other.
Porta cabins – The office structures
These days, people also prefer pre-fab offices than the traditional ones, these offices are built similarly and can be reassembled in cases of a location change. These offices have porta cabins which can be customized for designs, specifications as per the requirements. Porta cabins are convenient to move and shift. Porta cabin designs are usually varied, and they can be made to look as professional as desired. Porta cabins are very common in China, Gulf, Arab, Africa, Latin American countries.
Prefab homes – the preferred ones
Prefab homes have many advantages:
- They offer a significant saving in cost, time and effort.
- They are convenient and can be assembled and reassembled easily.
- The biggest advantage is that the construction is not affected by weather conditions and external factors as the manufacturing of components is done in factories.
- Completely customizable
It has a few disadvantages as well:
- Extra caution and care are required to transit the components; it may cause breakage and mishandling.
- Transporting components can be really costly.
- Skilled labour is needed, and in India we lack expertise in this area.
However, while the demand for such homes is increasing with changing trends expertise and skilled manpower will be easily accessible in the times to come. The advantages outweigh the disadvantages.
Luxury Prefab Homes in India
We will be surprised to know that there are manufacturers of luxury prefab homes in India also. In cities like Mumbai and Bangalore, this is a familiar concept. They use the best of the designs, materials and can make them as luxurious as desired.

Have you been on the lookout for solar panel manufacturers in India? Are you seeking the best companies that manufacture different types of solar panels? Then you’re reading the right article. This write-up gives you some of the best solar panel manufacturers in India. But before we delve into it, why don’t we try and explore the types of solar panels that are available in the market?
Types of Solar Panels
Solar has always been the way to go when it comes to generating electricity. However, one of the critical elements that constitute the generation of electricity through solar power is the type of panel used. There are different types of solar panels that are available, including sandwich panels, PUF panels and lightweight concrete panels. Let us look at them in brief.
- Sandwich Panels
Most solar panels today don’t seem to be able to catch the free power of the sun that is coming to them. So, it would simply be of no use installing solar panels to get solar power, if they can catch only some of the sun’s energy that is thrust upon them. Hence, there is a need to have three layers of solar panels sandwiched together. But that’s not all. Each layer is designed in such a way that it captures different wavelengths of the sunlight. In this way, they can be up to 35% more efficient, which is a huge bargain, as compared to single solar panels, which are only 15% efficient.As far as sandwich panels are concerned, the Indian company EPack Polymers which manufactures them offers a wide range of prefab villas to its customers. Some key highlights of the products made by EPS sandwich panel manufacturers in India or sandwich panels manufacturers in India include longevity, pristine finish, simple design, high-efficiency rating, and not to mention, resistance to cracks.
PUF is an acronym for Polyurethane Foam Insulation. Integrating joists, studs, insulation, vapor and not to mention, air barriers, these panels befit a wide variety of applications and are also easy to install. Epack is one of the best when it comes to PUF panel manufacturers in India, offering the best of the best prefabricated PUF panel roofing and wall cladding. Some benefits Epack offers include better thermal and acoustic insulation, energy savings, a durability for lifetime with high loadbearing capacities, water and vapor resistant, flexible when it comes to the design, and not to mention, easy to install and low maintenance costs.
- Lightweight concrete panels
The EPS wall panels designed by Satec EPS comprises both of exterior panels and not to mention, interior core fillings, forming a lightweight, non-load bearing composite wall panel with the outer panels having 5mm calcium silicate board on either side and polystyrene beads and cement-filled core in the middle. Some of the notable features of these panels include longevity, earthquake resistant, lightweight, easy installing, waterproof, low-cost and reusability.
The Boom of Modern Architecture- A glance at the emergence of prefabricated houses in India
The Modern Architecture
Gone are the days when the construction of a home or any building gave the immediate pain prolong wait and tons of time consumption until the final moving day.
Gratefully with modernization and technological development, the field of architecture and construction are pacing towards the creation of eco-friendly houses using solar structures etc. that are feasible to the dwellers economically and ecologically.
The Era of Modular Living
For instance, prefabricated houses or prefab houses or also known as specialist dwellings are manufactured in advance at off-site. The components are made separately at their different particular locations. They are then shipped to the position of erecting the building in standard segments and assembled at that place. It is as quick and flexible as site office construction.
Such modular homes are a well-depicted outcome of futurist architecture. They are built in panels or components. They are seamlessly mobile and can be transported from one place to another comfortably.
This architectural development is already catching grounds in the United States, Canada and Europe. Given the advantages of prefab homes like lesser construction time and cost-friendliness, the trend of prefab homes can acquire favour in India as well.
The Techniques Involved in Building Prefab Homes
Prefabricated homes are created majorly with these three primary techniques –
- Panel Built
- Manufactured Homes
- Modular Construction Technique
In the panel built technique, panels or components of wood or precast panels of concrete are formed at another site or off-site at factories. Concrete panels for exterior walls are widely preferred. If the panels are made of wood, then they are affixed together with nails, or when cement walls are used, then the panels are put together using steel beams and then filled with concrete to cement the strength further.
In the technique of manufactured homes, the entire building or the house is built from scratch till the end at another off-site location. The components are constructed and assembled at one place. It requires an entirely different location for the house to be built. When the construction is completed, then the house is then transported to the original location where it is meant to stand finally. The offsite installation works include plumbing, electrical fittings, heating of the floor or air conditioners fixture etc.
Modular construction technique refers to a building or fabricating the blocks of the buildings in modules. For example, the segments or modules of the structure like the living room, the kitchen, the den, the bathroom etc. are built separately and then are brought together and fixed at the final place. The components are constructed independently in factories at offsite construction locations and then are assembled to build the house in entirety. Portable cabins or porta cabins sized and styled variably are a part of this technique. The structures are constructed independently.
A prefab home is the ultimate future of the real estate industry. With its time and cost efficiency, it is the defining benchmark for modern-day housing culture.

How Relevant is Lightweight concrete in the Fast paced Construction Industry?
Lightweight concrete (LWC), the name says it all. It has been playing a significant role in the construction arena. This earthquake proofing concrete can either originate from natural resources like volcanic pumice or manufactured using by-products.
When it is made of a lightweight porous aggregate, it is called lightweight aggregate concrete. It is also manufactured by placing large voids within the concrete and is known as aerated.
AAC- Autoclaved aerated concrete:
- This building material was introduced in the mid-1920s and is now utilised in construction across various continents and climatic conditions.
- AAC is moulded into blocks, panels, roof panels and is also used for cladding.
- Autoclaved lightweight concrete is thermal efficiency and withstands high-temperature variations.
- Panels made of AAC are mainly used for roofs, floors, and walls. Manufactured with raw materials such as cement, lime, and silica, and steel mesh, these lightweight panels have high durability.
- Throughout the manufacturing process, i.e. until the waste disposal, AAC panel making has a low impact on the environment.
- Since the panels are moulded in a high temperature and pressure autoclave, they possess high compressive strength.
- AAC Panels are economical. They provide a rigid structure, insulation, and fire resistance.
- The aerated concrete panels are earthquake proof and also repel common house pests.
AAC Panels India
- As the Indian government is trying to provide economical houses to the citizens, AAC panels can be handy.
- These readymade panels are gaining popularity as they can be used in the construction right after purchasing them.
- The cellular concrete panels are available in India and the manufacturers growing every year.
Mepcrete AAC Panels: Branches are located in various cities of Tamil Nadu, Andhra Pradesh, and Karnataka.
- Mepcrete manufactures AAC panels which can be used in the construction of walls, floors, and roofs.
- Their AAC floor panels have high endurance and thermal absorption properties.
- Being lightweight, Mepcrete AAC floor panels are easy to install in the construction site.
- The wall panels manufactured by Mepcrete are dimensionally accurate, thanks to their steel reinforcement wires.
- Their AAC wall panels promise good thermal insulation.
- Unlike other roof panels, AAC roof panels constructed by Mepcrete have reduced thermal transference.
Satec Envir Engineering (India) Private Limited: Mumbai
- It is one of the noteworthy establishments in the construction industry when it comes to manufacturing of AAC panels.
- They provide AAC readymade panels which can be utilised for exterior wall, interior wall, flooring, roofing, cladding, and fencing.
- Also, Satec Envir ltd ensures a clean, polished and sophisticated look of the panels.
AAC panels are new to the construction industry in India though they encompass a large percentage of construction in other countries. This cellular concrete is an industrial revolution as thin-set mortar is used in its making process as opposed to the traditional cement-based mortar.
Lightweight concrete panels:
- With substantially lower weight than that of traditionally made concrete, lightweight concrete panels are increasingly becoming a demand in construction.
- These panels are made using coarse lightweight aggregates. These aggregates are expanded shale, clay or slate materials which when subjected to heat, develop into a porous structure.
- Lightweight concrete panels can be used for building walls, roofing, flooring, internal partitions. Some companies provide these panels as the material for prefabricated and relocatable buildings.
Bygone are the days when construction meant heavy materials and harm to the environment. Having many efficient manufacturers in every major city, construction is now done with lesser effort. With AAC panels and lightweight concrete, the industry is set to make construction earth-friendly.
