Custom Large-Span Prefabricated Steel Structure W | RFQ Sourcing Details

This prefabricated steel structure workshop is designed around project-specific dimensions, layouts, and operating requirements. The structural frame can use Q235 or Q345 steel, with hot-rolled or welded H-section columns and beams.

Painted and galvanized surface options are listed, while purlins may use C- or Z-section profiles. Available building arrangements include single-, double-, or multi-slope roofs;single- or multi-span layouts;and single- or multi-floor configurations.

Roof and wall options include corrugated steel sheet or sandwich panels insulated with EPS, rock wool, glass wool, or PU.

Listed sandwich-panel thicknesses range from approxima C or aluminum-alloy windows, sliding or roller-shutter exterior doors, skylight panels, ventilation, gutters, rainspouts, mezzanine floors, and provisions for an overhead crane.

Structural connections may include high-strength bolts, anchor bolts, and self-drilling screws. Fabricated members are described as pre-cut and pre-drilled for assembly at the project site, with installation guidance available.

Potential applications listed for this building system include workshops, factories, warehouses, storage sheds, office buildings, exhibition halls, gym sheds, aircraft hangars, poultry houses, food-processing facilities, chemical-industry facilities, textile and electronics processing, and heavy-industry buildings.

Suitability for any specific use must be confirmed through project engineering and applicable local requirements. Before procurement, the buyer should provide the required length, width, overall height, eave height, roof pitch, span arrangement, and floor configuration.

Door and window sizes, quantities, and positions should also be defined. Engineering inputs should include local wind speed, snow load, seismic requirements, intended occupancy, insulation needs, and any fire-protection requirements.

If an overhead crane is required, confirm its lifting capacity, lifting height, operating class, and structural loads.

Buyers should request project-specific drawings and calculations and confirm the applicable building codes, design loads, steel grades, coating or galvanizing system, corrosion environment, connection details, foundation interface, cladding thickness, insulation type, and accessory schedule.

Also verify the final bill of materials, packing method, erection responsibilities, inspection plan, and documentation supplied with the order. Certification scope and validity should be checked against the exact manufacturing and project requirements rather than assumed from a general listing.
