Pre Engineered Buildings

Engineering Steel. Building India.

Alphaspan designs and manufactures Pre-Engineered Building systems engineered to Indian codes, built to last, and delivered on time, from a 6,000 MT/year facility,

What Is a Pre-Engineered Building?

A Pre-Engineered Building (PEB) is a factory-engineered, steel-framed structure designed to precise specifications and delivered as a complete kit of parts — ready to erect on site with no cutting, welding, or guesswork. Every component, from primary rafters and columns to secondary purlins and cladding sheets, is designed, fabricated, and pre-drilled at our facility in Bangalore before it leaves our yard.

The result: faster construction, lower on-site waste, tighter cost control, and a structure that meets IS 800, IS 875, and NBC 2016 standards from day one.

Primary Framing Systems

The primary frame is the structural backbone of every Alphaspan building. We fabricate all primary frames from IS 2062 Grade steel using our in-house CNC plasma cutter and automated pull-through welding machine, ensuring dimensional accuracy and full weld penetration on every joint.

Our Infrastructure Includes

Multi-Span Rigid Frame

Multiple bays sharing interior columns — the economical solution for very large footprints where some internal columns can be accommodated in the layout.

Lean-To / Mono-Slope

A single-pitch frame that leans against an existing structure or stands independently. Commonly used for canopies, extensions, and covered walkways.

Lean-To / Mono-Slope

Multiple parallel gables on a shared base — suited to large industrial complexes where natural light and ventilation through ridge skylights are important.

We Provide the Best Service in Industry

Reliable pre-engineered building solutions delivered with excellence.

Secondary Structural Systems

Secondary members carry the cladding load and tie the primary frame together. At Alphaspan, secondary members are cold-formed on our in-house purlin profile machine to exact lengths — eliminating waste and ensuring fast, predictable erection.

Purlins & Girts: Z and C sections, galvanised cold-formed from high-tensile coil
Bracings: diagonal rod bracing, flange bracing, angle bracing — designed per wind zone
Eave Struts: structural members at eave line combining girt and purlin functions
Base Angles & Flashing: weatherproofing interface between structure and foundation
Mezzanine Floors: integrated steel mezzanines for office, storage, or production use

Accessories & Add-Ons

A complete Alphaspan building ships with all accessories included in the scope, no last-minute site procurement surprises.

Personnel doors and sliding / rolling shutter doors
Louvre windows and fixed glazing panels
Gutters, downspouts, and rainwater management

Design Standards & Engineering

Every Alphaspan building is designed by our in-house engineering team using STAAD.Pro structural analysis software, with detailing in AutoCAD. All structures are designed and checked against:

Mill Test Certificates (MTCs) for all structural steel are provided as standard. Third-party inspection is available on request.
