Prefab Buildings & Modular Building Systems
Factory-built, steel-framed and fully insulated buildings from Wedge Industries Limited — engineered for a 30+ year service life and delivered in just 4–6 weeks. Homes, cabins, offices, labour shelters, cold storage and mini agri-warehouses.
Why Build Prefab?
Insulated prefab construction beats conventional brick-and-block on speed, cost, energy efficiency and durability. Every Wedge building is precision-made in the factory on a high-strength steel frame, clad in MgO and cement board with a PUF and stone-wool insulated core.
shell build vs. 8–12 months masonry
wall weight vs. 400–500 masonry
guaranteed service life
built-in insulation, low HVAC cost
Prefab vs. Conventional Masonry
| Aspect | Conventional Masonry | Wedge Prefab / Modular |
|---|---|---|
| Construction time | Several months to over a year | Weeks — under 1 month for the shell |
| Energy efficiency | Needs added insulation | Insulation built in (R10 envelope) |
| Wall thickness | 230–350 mm external walls | 120–150 mm Wedge panels |
| Seismic performance | Poor — brittle | Excellent — ductile steel frame |
| Maintenance | Regular upkeep | Much lower — stable modern materials |
Our Prefab Building Range
A complete range of factory-built structures for residential, commercial, industrial and agricultural use.
1. Prefab & Modular Homes
Single-storey and duplex homes engineered with LGSF and steel-hybrid technology, clad in MgO & UV cement board with PUF and rockwool insulation. From compact 1 BHK cottages and modern studios to 3–5 BHK bungalows and duplex villas. Fireproof, earthquake-resistant and 40–60% faster to build.
2. A-Frame Cabins
Triangular A-frame studios with a loft — ideal for resorts, hillside getaways and rental units. Steel portal frame, insulated envelope, deck-ready facades.
3. Farmhouses, Villas & Luxury Estates
From orchard and resort cabins to two-storey duplex farmhouses and estate-grade G+1 luxury villas with glazed facades, wide verandas and designer interiors — all on a 30+ year steel envelope.
4. Building on Wheels (Mobile Homes)
Tiny homes on wheels (THOW), cottages, farm houses and studios on a trailer chassis — relocatable, off-grid ready and minimalist. Also configurable as mobile shops, health centres, mini cold storage and mini warehouses.
5. Prefab Offices & Porta Cabins
Low-cost portable offices and cabins with an integrated PU-foam roof and wall system: never-leak, excellent insulation, fast installation and long lifespan. Manager rooms with glass walls, site offices and security cabins.
6. Labour Rooms & Shelters
Durable, low-cost accommodation for construction and industrial workforces — integrated PU-foam roof and wall, organised drainage and rapid site installation.
7. Cold Storage & Refrigerated Warehouses (EPC)
Turnkey EPC cold storage — bulk cold stores, refrigerated warehouses, multi-commodity cold rooms, ripening chambers, pharma cold storage and modular cold rooms. PUF-panel envelope, ammonia or Freon refrigeration, IoT temperature and humidity control. Capacities from a few hundred to 5,000+ MT.
Mini Cold Storage & Mini Rural Agri Warehouses
Purpose-built for farms, FPOs, dairies, horticulture clusters and rural markets — compact, modular, plug-and-play cold rooms and agri storage that bring the cold chain to the farm gate and cut post-harvest losses.
Mini & Micro Cold Storage
Modular PUF-panel cold rooms, factory-built and site-assembled in days. Available as fixed installations or mounted on wheels for mobile field storage. Ideal for potatoes, fruits, vegetables, flowers, dairy and vaccines.
| Feature | Specification |
|---|---|
| Envelope | Insulated PUF sandwich panels, vapour-barrier sealed |
| Temperature range | Chilled 2–8°C (potatoes 4–6°C) to frozen sub-zero |
| Humidity control | ~85–90% RH to prevent sprouting and rotting |
| Refrigeration | Inverter compressors, load-sharing with backup |
| Power options | Grid, generator or solar-ready off-grid |
| Configuration | Fixed on-site or mobile on-wheels; scalable, modular |
Mini Rural Agri Warehouses
Small prefab / PEB warehouses for grain, produce, seed, fertiliser and farm-input storage — steel-framed, insulated and ventilated to protect stock in rural conditions. Quick to erect, expandable in bays, and suitable for FPOs, mandis, cooperatives and agri-input dealers.
- Steel portal / PEB frame with insulated roof and wall panels
- Ventilation and moisture control to protect grain and produce
- Wide clear spans for stacking, racking and easy handling
- Modular bays — extend as storage needs grow
- Combine with a mini cold room for mixed dry + cold storage on one site
Typical buyers: farmers & FPOs, dairy and horticulture units, cold-chain operators, agri-input dealers, rural entrepreneurs and government / PACS schemes.
The Wedge Wall System
A high-strength steel frame clad in Wedge cement and MgO boards with an R10 insulated core — the complete external wall in a 120 mm build-up, outside to inside.
| Layer | Material | Thickness |
|---|---|---|
| Cladding | UV-coated high-strength cement board | 8 mm |
| External board | Waterproof perlite-magnesia (MgO) board | 12 mm |
| Frame + insulation | Galvanised steel C-sections + R10 HD stone wool | 90 mm |
| Internal board | MgO board, finish-ready | 10 mm |
| Total | Complete insulated wall | 120 mm |
R10 insulation · 48–55 dB acoustic rating · non-combustible boards · waterproof, mould-resistant envelope · 30+ year guaranteed life.

Frequently Asked Questions
How long does a Wedge prefab building take to deliver?
Most prefab buildings are delivered in 4–6 weeks from design freeze. The shell is typically raised in under one month — far faster than the 8–12 months a masonry equivalent takes.
Are prefab buildings durable and safe?
Yes. Wedge buildings use a galvanised light-gauge steel frame clad in MgO and cement board, engineered for a 30+ year service life. They are non-combustible, resist rot, termites and corrosion, and flex safely under seismic load.
What is a mini cold storage and who is it for?
A compact, modular PUF-panel cold room — fixed or on wheels — built for farms, FPOs, dairies and horticulture clusters. It holds chilled 2–8°C to sub-zero at ~85–90% RH, cutting post-harvest losses.
What is a mini rural agri warehouse?
A small prefab / PEB warehouse for storing grain, produce, seed, fertiliser and farm inputs. Steel-framed, insulated and ventilated, it erects quickly and expands in modular bays.
Can buildings be relocated?
Yes. Our Building-on-Wheels range — tiny homes, cottages, shops, mini cold storage and mini warehouses — is built on a trailer chassis so it can be transported and re-sited.
Do you deliver outside India?
Yes. Wedge Industries operates manufacturing bases in India, UK, Spain and China and exports to 45+ countries, including the Gulf, UK, USA and Australia.
