So What Exactly is a
Pre-Engineered Building?
Many business owners ask us this all the time. Let us explain it in the simplest way possible. Imagine you are ordering furniture from a shop. Instead of a carpenter coming to your home and building everything from scratch, you order a ready made sofa, table and chairs. They are manufactured in a factory, delivered to your home and assembled in a few hours.
A pre-engineered building works exactly the same way. The entire steel structure, columns, beams, roof panels, wall panels, everything is designed on a computer, manufactured in our factory with high precision, transported to your site and assembled by our expert team. That's it, simple as that.
No messy construction for months, no unexpected delays, no daily supervision headaches. Just a strong, durable pre engineered steel building delivered and assembled at your site, ready to use.
How Do We Build a PEB
at Thirumala Roofings?
As leading PEB building manufacturers, here is our simple step by step process that we follow for every project.
We Listen to You
First we understand your requirements. What size do you need? What will you use it for? Where is your site located?
Our Engineers Design Your Building
Our experienced team designs your entire pre-engineered steel building using advanced software. Every bolt, beam and panel is planned perfectly before manufacturing begins.
Manufacturing in Our Factory
All components are manufactured in our factory under strict quality control. This is what makes pre-engineered buildings so precise and reliable compared to conventional construction.

All the manufactured components are carefully packed and transported directly to your site.

Handover
Your brand new PEB building is ready. Most pre-engineered building projects are completed in just 45 to 90 days.
What Goes Inside a
Pre-Engineered Steel Building?
Apart from understanding what a pre-engineered building is, many clients ask what actually goes inside one. Here is a simple breakdown of every component.
Primary Steel Frame
This is the backbone of your PEB building. The main columns and rafters that hold everything together.
Secondary Members
These are the purlins, girts and eave struts that support the roof and wall panels of your pre-engineered building.
Roof Panels
High quality roofing sheets that protect your pre-engineered steel building from rain, heat and wind, very important for a coastal climate.
Wall Panels
The side walls of your pre-engineered building that provide enclosure and insulation.
Doors and Windows
Designed as per your requirements for proper access and ventilation in your industrial shed construction.
Mezzanine Floor
If you need an additional floor inside your PEB building for office space or storage, we can add that too.
Every single component in our pre-engineered steel buildings is manufactured to exact specifications, nothing is left to chance.
PEB vs Conventional Building
Which is Better?
This is probably the most common question we hear from factory owners and businessmen. So let us be completely honest with you.
Need It Fast
PEB wins. A conventional RCC building takes 6 to 12 months minimum. Our pre-engineered buildings are ready in just 45 to 90 days, so you can start operations much faster.
Want to Save Money
PEB wins. Lower labour costs, zero material wastage and faster completion all add up to significant savings compared to conventional construction.
Want Quality
PEB wins. Factory controlled manufacturing means every component meets exact quality standards. With conventional construction, quality depends on daily site conditions, workers and weather.
Want Flexibility
PEB wins. Need to expand your warehouse in a few years? No problem. Pre-engineered buildings can be easily extended without major disruption to your existing operations.
So when does conventional construction make sense? For multi-storey residential buildings or highly complex architectural designs, conventional construction may still be preferred. But for warehouses, factories and industrial shed construction, pre-engineered building is almost always the smarter choice.
