Customized Prefab Steel Structure Building for Logistics Center
The main frame uses high-strength H-Beam Q355B steel that can be engineered with wide clear spans, giving forklifts and automated guided vehicles (AGVs) clear paths. The columns are anchored to the ground with Q235B bolts and joined with Grade 10.9 high-strength bolts to withstand continuous operational vibrations.
Yes. The exterior uses high-quality Galvalume color sheets or insulated sandwich panels sealed with industrial weatherproofing. Rainwater is moved away by deep stainless steel gutters and Φ110 PVC downpipes, while Φ600mm 304SS unpowered ventilators exhaust indoor humidity to prevent condensation.
Absolutely. Because the structure uses a flexible H-beam design and customizable Q235B C-section wall purlins, wall openings can be adapted to fit your architectural blueprints. This allows the seamless placement of sectional loading dock doors, commercial rolling shutters, and dock leveler frames.
Standard paint can scratch and rust over time, especially in busy logistics areas. This building features a thick 275g hot-dip galvanized coating on all Q235B C-section roof and wall purlins. This heavy zinc layer provides a sacrificial barrier that prevents rust even if the surface is scraped.
Yes, the entire package is pre-fabricated. All H-beams, purlins, bracing rods (Φ20/Φ12), and tie rods (Φ89×3) are cut, drilled, and coated according to your engineering drawings. They are packed for container shipping and arrive ready to bolt together on-site with the included Grade 10.9 and Grade 4.8 hardware.
