Pre-Engineered Steel Building with 50 Years Usage Life, High Corrosion Resistance, and Bolt or Welded Connection for Industrial Warehouses
Pre-engineered steel buildings are steel structures built over a structural concept of primary members, secondary members, roof and wall sheeting connected to each other and various other building components.
These buildings can be provided with different structural and non-structural additions such as skylights, wall lights, turbo vents, ridge ventilators, louvers, roof monitors, doors & windows, trusses, mezzanine floors, fascias, canopies, crane systems, insulation, etc., based on customer requirements. All steel buildings are custom designed to be lighter in weight and high in strength.
Pre-Engineered Buildings are the most flexible solutions for contractors and owners. With advantages of low cost, high durability, perfect quality control and fast erection, PEBs are used for various applications including factories, warehouses, logistics centers, showrooms, shopping malls, schools, hospitals, and community buildings.

Price per square meter can be 25%-30% lower than conventional steel buildings. Site erection cost is low due to faster erection times and easier installation process.
All steel components are fabricated at the factory and linked by bolts at the site. Erection process is fast, step-by-step, easy to install and requires simple equipment. 60% less construction time required compared with traditional R.C.C buildings.
Pre-engineered steel buildings are flexible in design requirements, easy to expand in the future, and economical with low transportation costs.
Pre-engineered buildings are the green solution for the environment with CO2 reduction, energy efficiency, and recyclability.
Pre-engineered metal buildings consist of the following components:
- Primary Members / Main Frames
- Secondary Members / Cold Formed Members
- Roof & Wall Panels
- Accessories, Buyouts, Crane System, Mezzanine System, Insulation, etc.
- Sandwich Panels
Primary members are the main load carrying and support members of a pre-engineered building. The main frame members include columns, rafters and other supporting members. The shape and size vary based on application and requirements.
Secondary structural framing refers to purlins, girts, eave struts, wind bracing, flange bracing, base angles, clips and other miscellaneous structural parts. Purlins, girts and eave struts are cold formed steel members with minimum yield strength of 345 MPa (50,000 psi) conforming to GB/ISO/CE standards.
Standard steel panels are 0.3, 0.4, 0.5 mm or 0.6 mm thick with minimum yield strength of 345 MPa. Steel panels are hot dipped and galvanized with zinc or zinc-aluminium coating. Base material is pretreated before applying corrosion resistant primer and top coat.
Building accessories include anchor bolts, fasteners (bolts, nuts, turnbuckle, expansion bolts), gutters, downspouts, doors, windows, ventilators, skylight panels, louvers and all other building-related materials.
- Verify receiving documents and material quantity
- Submit materials for QC inspection
- Visual inspection for surface condition and damages
- Dimensional inspection for length, width, depth, thickness
- Material Test Certificate verification
- Preparation of Incoming Material Inspection Report
Design department creates structural drawings. Production department prepares items as per drawings:
- Transfer drawings to automated processing machines
- Automated punching of part marks
- Precision drilling as per NC files
- Plasma cutting of plates
- Automated cutting and drilling as per fabrication drawings
- Transfer to fit-up section after processing
Fabricators collect prepared beams and connection details for fit-up. End plates, gusset plates, stiffeners, purlin cleats, stay angle cleats are fixed in appropriate places by tack welding. Completed fit-up is offered to QC for inspection.

- Set wire feed and voltage parameters
- Maintain fillet size per GB50661-2011 standard
- Remove spatters and slag completely
- Grind burrs, sharp edges and excessive reinforcements
- QC inspection after completion
- Plan welding jobs systematically
- Clean welding locations thoroughly
- Set wire feed and voltage parameters
- Maintain fillet size per GB50661-2011 standard
