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.
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).
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.

Steel plate cutting → H section assembly → Automatic welding → H section strengthening → Assembly → Manual welding → Shot blasting → Painting → Storage
H section steel plate checked by factory and applied under design requirements. CNC cutting equipment preferred for cutting. High purity 98.0% acrylic gas and 99.99% liquid oxygen gas used to guarantee smoothness and flatness of cutting surface.
Equipment Specifications:
Assembly process set up on imported H section production line. 4 hydraulic positioning system press firmly between upper/lower flange and web plates. Adjust parallelism of flange plates and perpendicularity between flange and web plates.
Equipment: H section steel assembly machine (Z20B) - flange width 150-800mm, web height 160-2000 mm
H section steel members hoisted into gantry-type submerged arc automatic welding machine for welding. Welding process carried out according to specified welding sequence and regulation parameters.
Equipment: Gantry-type submerged arc automatic welding machine (LHA5ZB) - maximum cross section up to 800mm*2000mm
Correction of flange flatness using H section steel flange plate strengthening machine. Flame-correct perpendicularity between H section flange and web plate. Control flame temperature between 600~800ºC.
Equipment:
Manual welding processes as required for specific components and connections.
Equipment: 10-ramming heads shot blasting machine (QH1525) - mainly for shot blasting of section steels including H section steel, welded members and steel plate. Machine entry size: 1500*2500, up to Sa2.5 Grade.
Surface of members should be even, flat, glossy and full painting without manifest of cracking, peeling and pin holing. Color and coating thickness should meet design requirements.
Standard Requirements:
Equipment: Airless sprayer (CPQ9CA) - derived capacity: 56 L/min, air consumption: 50~1200 L/min, pressure ratio: 32:1
