Pre-engineered steel buildings (PEB) are structural concepts consisting of primary members, secondary members, and roof/wall sheeting connected together. These buildings are custom-designed to be lighter in weight yet high in strength, allowing for various additions such as skylights, mezzanine floors, and crane systems.
Pre-Engineered Buildings are the most flexible solutions for contractors and owners, offering low cost and fast erection across various sectors:
Factories, Workshops, Warehouses, Cold Storages, Steel Mills, Assembly Plants.
Showrooms, Supermarkets, Offices, Shopping Centers, Restaurants, Logistic Centers.
Includes columns, rafters, and support members that carry the main load of the building.
Secondary Framing: Purlins, girts, and eave struts with minimum yield strength of 345 MPa.
Roof & Wall Panels: Standard thicknesses of 0.3mm to 0.6mm, hot-dipped and galvanized with zinc-aluminum coating for corrosion resistance.
A. Material Receiving: Dimensional and visual QC inspection, verifying MTC heat numbers.
B. Preparation: CNC plate processing including plasma cutting, punching, and drilling.
C. Fit-up & Welding: Automated submerged arc welding and MIG welding following GB50661-2011 standards.
Surfaces are cleaned to Grade SA 2/2.5. Painting includes primer and finish coats with airless sprayers to ensure a glossy, even finish of 125-150μm thickness.
| Form of Fillet Weld | Fillet Weld Size (K Value) | Application Note |
|---|---|---|
| Without Groove | K=(0.7~1)t and ≤15mm | Standard steel structures |
| Secondary Members | K=(0.5~0.6)t | Strengthening ribs |
| CJP / PJP Groove | K=t/4 and ≤10mm | General construction |
| Important Members | K=t/2 and ≤10mm | Crane beams / Web plate connections |
