Descripción de producto

Prefab Heavy Steel Structure Building for Office & Hotel Use with Welding & Cutting Services Included

Our heavy-duty steel structure buildings are engineered for large-scale commercial applications including offices and hotels. Built with high-strength heavy steel components and thickened load-bearing frames, this series boasts superior structural stability, heavy load capacity, wind and snow resistance. With hot-dip galvanized or painted anti-corrosion treatment, the buildings deliver long service life and adapt to harsh cold, high humidity and coastal extreme weather conditions. We provide fully customized size, span and structural design to meet commercial building demands.

One-stop provider from design and fabrication to installation for Pre-engineered Buildings and Structural Steel

Key Advantages

Superior Load-Bearing Capacity - Adopting high-strength steel with yield strength up to 345–690MPa, supporting heavy cranes (25t, 50t, 100t+), heavy-load floors, and long-span column-free spaces.
Excellent Seismic & Wind Resistance - Outstanding plasticity and toughness, meeting seismic fortification intensity 8+, ensuring safety in high-seismic and coastal strong-wind areas.
Factory Prefabrication & Efficient Delivery - Full-process factory prefabrication, shortening construction period by 30%–60% compared with concrete structures.
Maximized Space Utilization - Small cross-section and high bearing capacity enable extra-long span and super-high clearance, improving usable area and logistics efficiency.
Long-Lasting Anti-Corrosion & Durability - Standard surface treatment: sandblasting Sa2.5 + zinc-rich epoxy primer + epoxy intermediate coat + polyurethane topcoat.
Eco-Friendly & Low-Carbon - Dry construction minimizes pollution. Steel is 100% recyclable, fully compliant with global green building policies.
