Prefabricated Steel BuildingsManufacturer in Kolkata
Jadro Steel LLP is a prefabricated steel building manufacturer in Howrah, serving Kolkata and all of eastern and Northeast India. We design, manufacture and erect LGSF prefab houses, steel structure buildings, factory sheds and warehouses from our own factory — delivered across 15+ states. Our buildings put a primary steel frame under the span and light gauge steel framing around the walls and roof, giving a 30-metre clear span with a cool, quiet, finished interior — built 2x faster than brick and RCC.
What Types of Prefabricated Buildings Does Jadro Build?
From prefab homes and site offices to factory sheds and warehouses — Jadro engineers and builds the right steel system for your site and budget.

LGSF Prefab Houses
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.
A hot-rolled steel 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.
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.
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.

Step 1 of 5
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.

Step 2 of 5
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.

Step 3 of 5
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.

Step 4 of 5
Steel Structure Erection
On hybrid steel 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.

Step 5 of 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.
Design, fabrication and erection under one contract. Send us your plot size, building type and location — that is enough for a detailed quote.
Every frame is roll-formed at our own factory in Panchla,
Howrah, then delivered cut, punched and numbered. Proximity matters in steel
— it decides your freight cost and your delivery date.

An LGSF structure is a building frame made from thin, cold-formed galvanised steel sections (studs, tracks, joists and trusses) screwed together into wall, floor and roof panels that carry
Ask three companies what a prefab house costs and you will get three answers that do not even look related. One sends a WhatsApp message quoting a lakh and a half.
If you are planning to build a home or commercial building in India, you have probably heard about LGSF (Light Gauge Steel Frame) construction and wondered how it compares with the traditional bric
"What is the cost of LGSF construction per square foot?" This is the first question every client asks, and unfortunately, most answers online are either outdated, vague, or misleading.
Jadro Steel LLP manufactures prefabricated steel buildings — LGSF prefab homes, villas, site offices and showrooms; steel structure factory sheds, warehouses and godowns; and large-span commercial steel buildings like schools, hospitals and banquet halls. We handle design, factory fabrication and site erection in-house from our Panchla, Howrah facility.
Is a prefab steel building cheaper than brick and RCC?
+
On total project cost a prefab steel building is broadly comparable to good-quality conventional construction — but it finishes 30–50% faster, needs a lighter and cheaper foundation, and produces almost no site wastage. Where it wins clearly is on time-to-occupancy and on lifetime maintenance, since there is no plaster cracking, no damp, and no termite treatment.
How much does a prefabricated steel building cost per sq ft?
+
Cost depends on the system and finish level. A basic industrial shed shell sits at the low end of the market range; a fully finished prefab house or a steel building with an insulated envelope sits considerably higher. The most common pricing mistake is comparing a structure-only quotation against someone else's turnkey figure — they are different products. Send us your plot size and building type for an itemised quotation.
How fast can a steel structure building be constructed?
+
An LGSF site office can be structurally complete in 2-4 weeks, an LGSF home in 8-16 weeks, and a prefab steel industrial building in 3-6 months — typically 30-50% faster than equivalent RCC construction, because components are factory-fabricated while site foundations progress in parallel.
