Large Span Hot-Dip Galvanized Q355 Prefabricated Portal Frame Steel Structure Industrial Werehouse Building

Q355 High-Strength Steel Structure: Made of Q355 low-alloy steel with 355MPa minimum yield strength, it features stronger load-bearing capacity, rigidity and seismic performance than ordinary carbon steel, ensuring long-term structural safety for heavy industrial storage.

Large-Span Portal Frame Layout: Optimized portal frame design supports 12–72m+ clear column-free spans, creating spacious and flexible open interior space, perfectly adaptable to large logistics storage, bulk cargo stacking and automated warehousing layout.

Full Hot-Dip Galvanized Protection: All main steel members adopt hot-dip galvanizing treatment, forming a dense anti-rust zinc layer to effectively resist moisture, saline-alkali and chemical corrosion. It ensures 40–50 years of service life even in humid coastal and rainy industrial environments.

Prefabricated for Rapid Construction: 100% CNC factory prefabrication with high dimensional accuracy. Bolted on-site assembly shortens construction cycle by 50–60% compared with traditional concrete warehouses, realizing fast delivery and early project operation.

Flexible Customized Configurations: Fully customizable eave height, roof slope, bay distance and overall layout. Optional insulated sandwich panels, rolling doors, ventilation skylights, crane beams, mezzanine floors and fire protection systems to satisfy diverse industrial storage demands.

Reliable Weather Resistance: Standard design resists 120–160km/h wind load and 7–8 degree seismic intensity. Targeted reinforcement schemes are available for typhoon-prone or high-seismic zones to maintain stable performance under extreme weather conditions.

Cost-Effective Lifecycle Value: Lightweight steel structure reduces foundation engineering cost; short construction period cuts capital occupation cost. Low daily maintenance and 100% recyclable steel effectively lower long-term operation and reconstruction expenses.

Eco-Friendly Green Building: Factory prefabrication minimizes on-site construction waste, dust and noise pollution. Over 90% recyclable steel components greatly reduce carbon emissions, fully meeting global green construction standards.

International Quality Compliance: Produced strictly in accordance with GB, ASTM, AISC and AS/NZS building codes. Strict raw material and welding quality inspection, with BV, SGS, TÜV third-party certification available for global export projects.

Wide Industrial Application Scenarios: Ideal for logistics distribution centers, manufacturing raw material warehouses, bulk cargo storage yards, e-commerce fulfillment centers and industrial park supporting facilities, suitable for both domestic and overseas industrial construction projects.
