Pre-Engineered
Buildings (PEB)

Engineered for Strength. Built for Faster Execution.

Rooffit delivers Pre-Engineered Buildings (PEB) for industrial, commercial and infrastructure projects requiring structural strength, efficient construction and long-term performance.

As an experienced PEB manufacturer in India, Rooffit brings together engineering, fabrication, roofing, cladding, supply and erection capabilities to provide coordinated steel building solutions tailored to project requirements.

Every PEB structure integrates primary framing, secondary framing, roofing, wall cladding, bracing and project-specific accessories into one engineered building system.

Rooffit provides PEB solutions in India for manufacturing facilities, warehouses, logistics centres, commercial buildings, cold stores and infrastructure projects.

Pre-Engineered Buildings

What Are Pre-Engineered Buildings?

A Pre-Engineered Building, commonly known as a PEB, is a structural steel building system in which major structural components are engineered and fabricated according to project requirements before being assembled at site.

A typical PEB steel structure consists of:

  • Primary structural framing
  • Secondary framing members
  • Roof purlins and wall girts
  • Eave struts and bracing systems
  • Roofing and wall cladding
  • Building accessories
  • Project-specific structural components

Because major components are engineered and fabricated before reaching site, PEB construction allows fabrication, transportation and erection to follow a planned process.

Rooffit develops PEBs around building dimensions, structural loads, clear-span requirements, roof configuration, operational needs, crane systems, mezzanine requirements and future expansion considerations.

Rooffit – PEB Manufacturer in India for Industrial & Commercial Projects

Rooffit provides integrated Pre-Engineered Building solutions covering engineering, structural fabrication, roofing, cladding, supply, painting and installation.

Primary Framing System in a PEB Structure

The primary framing system forms the main load-bearing structure of a Pre-Engineered Building.

Rooffit’s primary framing consists of columns and rafters with tapered webs and variable flanges. Cut steel plates are welded to form the required sections, with fabricated sections connected at site using bolted splices.

Depending on structural design, main PEB frames can have fixed or pinned bases.

The system is developed according to:

  • Building width and length
  • Clear span and eave height
  • Structural loads
  • Crane requirements
  • Internal operating space
  • Roof configuration
  • Future expansion requirements

Secondary Framing System for Pre-Engineered Buildings

Secondary framing supports the roofing and wall systems and transfers loads to the primary frame.

Typical components include:

  • Roof purlins
  • Wall girts
  • Eave struts
  • Structural clips and connections
  • Bracing elements

Rooffit’s PEB specifications use cold-formed Z-sections for purlins and girts.

Secondary Framing Specifications

Purlin Depth120 mm to 300 mm
Purlin Flange Width50 mm to 100 mm
ThicknessApproximately 1.52 mm to 2.5 mm
Minimum Yield Strength345 MPa

Purlins are fixed to rafter top flanges using clips, with purlin webs bolted to the clips. Purlin ends overlap to function as continuous beams.

Wall girts are also cold-formed Z-sections, with PEB specifications covering depths of approximately 150 mm to 250 mm and thicknesses of 1.5 mm to 2.5 mm.

Together, primary and secondary framing create the structural framework supporting roofing, cladding and associated components.

Roofing & Cladding for PEB Buildings

The building envelope contributes to weather protection, functionality, daylighting, ventilation and appearance.

Rooffit’s wider product portfolio allows roofing, cladding and building-envelope requirements to be incorporated into industrial PEB buildings.

Available solutions include:

  • Metal roofing and cladding profiles
  • Klip Lok profiles
  • Standing-seam roofing
  • FRP and polycarbonate sheets
  • PUF insulated panels
  • Ventilation products
  • Building accessories

The final structural configuration depends on project-specific dimensions, loads, functional requirements and building configuration.

Clear-Span PEB Solutions for Industrial Buildings

Industrial buildings often require large internal working areas with minimal interior columns.

Rooffit’s PEB solutions offer clear spans in the 70–80 metre range for industrial applications. Such configurations can support manufacturing, warehousing, material movement and other operations requiring uninterrupted space.

The appropriate span and structural arrangement are determined according to project engineering requirements.

Crane Systems

Rooffit’s crane systems include:

  • EOT overhead cranes with pendant or cabin operation
  • Overhung crane systems
  • Underhung crane systems
  • Monorail crane systems
  • Wall-mounted cranes
  • Jib cranes

Suitable PEB configurations can also incorporate crane beams, allowing building structure and material-handling requirements to be considered together during engineering.

Mezzanine Systems for Better Use of Building Space

Pre-Engineered Buildings can incorporate mezzanine systems where additional usable floor space is required.

Rooffit provides mezzanine systems for:

  • Office areas
  • Storage areas
  • Operational spaces

Depending on loading requirements, intermediate mezzanine floors can be configured as composite or partial areas within a PEB, allowing building height to be used more effectively without necessarily increasing the overall footprint.
