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:
Price per square meter can be 25%-30% lower than conventional steel buildings. Site erection cost is low because of faster erection times and easier erection process.
All steel components are fabricated at the factory and linked by bolts at the site. So the 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 (reinforced concrete) building.
Pre-engineered steel buildings are flexible in any requirement of design, easy to expand in the future and also economically with low transportation costs.
Nowadays, pre-engineered buildings are the green solution for the environment with CO2 reduction, energy efficiency, and recyclability.
Pre-engineered metal buildings consist of following components:
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 of these members vary based on the 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 which have a minimum yield strength of 345 MPa (50,000 psi) and will conform to the physical specifications of GB/ISO/CE or equivalent.
Standard steel panels are 0.3, 0.4, 0.5 mm or 0.6 mm thick and have a minimum yield strength of 345 MPa. Steel panels are hot dipped and galvanized with zinc or zinc-aluminium coating. The base material is pretreated, before applying a corrosion resistant primer and top coat.
Other 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.

Submerged Arc Welding Procedure:
MIG Welding Procedure:
With 20 year warranty in the steel building industry, our company maintains strict quality standards. We have acquired ISO9001 and CE certificates and follow these related standards:
Purpose: To ensure quality of fillet weld, meeting technical requirements of welded members and improve standardization of fabrication.
Application Scope: Applies for design, fabrication and inspection of fillet weld size.
Fillet Weld Leg Size Requirements:
| Form of Fillet Weld Leg | K (Fillet Weld Size) Value | Note |
|---|---|---|
| Fillet weld without groove | K=(0.7~1)t and ≤15mm | For most steel structure buildings |
| Fillet weld without groove | K=(0.5~0.6)t | For strengthening ribs and secondary members |
| Fillet weld with groove (CJP and PJP) | K=t/4 and K≤10mm | For most steel structure buildings |
| Fillet weld with groove (CJP and PJP) | K=t/2 and K≤10mm | Important members (crane beams) |
| Parent Metal Thickness (t)(mm) | Minimum Fillet Weld Size |
|---|---|
| t≤6 | 3 (minimum 5 for crane beam) |
| 6 | 5 |
| 12 | 6 |
| t>20 | 8 |
