Pre-engineered steel buildings (PEB) are structural concepts consisting of primary members, secondary members, and cladding (roof and wall sheeting) connected to each other. These buildings are custom-designed to be lighter in weight and high in strength.
Price per square meter can be 25%-30% lower than conventional steel buildings. Low site erection costs due to fast installation.
Factory-fabricated components linked by bolts. Reduces construction time by up to 60% compared to traditional concrete structures.
Flexible design requirements that are easy to expand in the future. Economical transportation and lightweight structure.
Green solution for the environment with CO2 reduction, high recyclability, and excellent thermal insulation options.
Primary members include columns and rafters which carry the main load. Secondary members consist of purlins, girts, and eave struts (minimum yield strength 345 MPa).
Standard panels range from 0.3mm to 0.6mm thickness with zinc or zinc-aluminum coating for superior corrosion resistance.
Automatic blasting achieves Grade SA 2.5. Painting includes primer and finish coats with controlled WFT/DFT thickness according to GB50205 standards.
