Most Popular
LGSF Prefab Buildings
Light gauge steel framing is India's fastest-growing prefab building system. Prefab homes, villas, site offices, showrooms and rooftop extensions — structurally complete in weeks, not months, with factory-cut components that fit first time.
Large Scale
Hybrid Steel Buildings
A PEB primary frame for the span, with LGSF wall and roof framing for an insulated, finished envelope. Clear spans past 30 meters for factory sheds, prefabricated warehouses, banquet halls and school blocks, hotels.
Engineering
Architectural Design
In-house architects and structural engineers produce approval-ready drawings coordinated with the steel system from day one — so what gets drawn is what gets fabricated, with no redesign loop between architect and factory.

How a Prefabricated Steel Building Is Made
Jadro manufactures prefabricated steel buildings in our own unit at Panchla, Howrah. Light gauge steel framing for buildings up to G+3, and hybrid — a hot-rolled frame with light gauge walls and roof — for wide-span factory sheds and warehouses.

1
Design and Engineering
We size the structure before we quote it. Wind, seismic and roof loads are calculated for your actual site, and that calculation decides the system — light gauge framing alone, or a hot-rolled frame underneath. You approve one set of drawings, and those drawings become the manufacturing file.
-
2
Steel Fabrication in Our Factory
Both systems are produced on our own shop floor at Howrah. Galvanized coil runs through the roll-forming line into studs and wall panels, punched to the millimetre. Columns and rafters are cut, drilled and welded in the fabrication bay. Same drawings, same quality control, no subcontractors.
-
3
Foundation and Delivery to Site
Your foundation is cast while fabrication runs, so neither waits on the other. Components leave the factory numbered and sequenced in erection order. That sorting is what keeps a prefabricated building fast — it happens here, on our floor, not on your site.
-
4
Steel Structure Erection
On hybrid buildings the hot-rolled frame goes up first — columns set, rafters connected, structure plumbed and levelled. Light gauge panels then fix to it. On LGSF buildings the panels stand on their own. A skeleton that takes months in brick and RCC stands in days.
-
5
Cladding, Insulation and Finishing
Sheeting or boards close the walls and roof, insulation fills the cavity, and services run through pre-punched holes instead of chased brickwork. Doors, windows and finishes go on last. The finished building looks conventional — it just went up in a fraction of the time.
