Product Details
What is a Steel Structure Building?
Steel structure buildings consist of H-beams/columns, purlins, roof panels, wall panels, roller shutters, and windows. They are typically constructed using high-quality steel, with the main structure conforming to Q355B/ASTM A572 Gr.50/EN S355/JIS SM490, and secondary structures to Q235B/ASTM A36/EN S235JR/JIS SS400. Connections are usually bolted for easy assembly and disassembly, or welded for increased rigidity. Lateral resistance members, including bracing and shear walls, enhance the building's seismic and wind resistance. Auxiliary components such as fasteners, sealants, and insulation materials also play a crucial role in ensuring the building's functionality and durability.

Product Applications
Agricultural Buildings
Large-span column-free spaces, excellent ventilation and lighting, economical cost, short construction period, corrosion and moisture resistance, flexible modification (suitable for various business formats such as aquaculture, planting, warehousing, and agricultural product processing), wind and earthquake resistant (suitable for rural and suburban outdoor environments).
Industrial Buildings
Extra-large spans, extra-high headroom, heavy load-bearing capacity (suitable for large equipment, cranes, and cargo stacking), fast construction (shortening factory commissioning time), earthquake and impact resistant, expandable/relocatable, and compliant with regulations.
Special Shape Structures
Personalized design, curved/irregular space realization, lightweight structure with stability, large-span unsupported design, strong visual appeal (suitable for landmark buildings, specialty venues, etc.).
Commercial Buildings
Core requirements: large-span atrium/double-height spaces, modern and beautiful design, fast construction (shortening the commercial project leasing/opening period), flexible floor height adjustment, suitable for high-traffic areas requiring earthquake and fire resistance, and can be upgraded later (suitable for adjustments to business formats).
Residential Buildings
Earthquake and wind resistant, fast construction, flexible unit layouts, thermal insulation, environmentally friendly and energy-saving, controllable costs, suitable for high-rise, multi-story, and low-rise residential buildings, and meeting residents' comfort needs.
Public Buildings
Large spans, spacious layouts, iconic designs, high earthquake and wind resistance, safe and durable (service life ≥ 50 years), suitable for high-traffic areas, compliant with fire safety and accessibility design standards for public buildings, and also considering cultural and functional expression.
