Fire Resistant Pre Engineered Q335B Steel Frame Storage Warehouse Wide Span

Our pre-engineered steel storage and prefab steel warehouse is a fully customized industrial steel structure solution designed for global logistics, manufacturing, and bulk storage scenarios. As a professional energy-saving insulated sandwich panel steel warehouse supplier, we integrate thermal insulation, fire prevention, corrosion resistance, and seismic performance into one complete system.

This durable steel structure storage adopts steel portal frame warehouse architecture, supporting large span steel warehouse and wide span metal warehouse design without intermediate columns, maximizing internal storage space. Available as factory prefabricated warehouse and complete steel warehouse package, our products cover two core functional types: fire resistant steel warehouse and fireproof storage building, fully compliant with international building codes.

Built with grade steel frames and premium envelope materials, this long-lasting metal warehouse building delivers a 50+ year warehouse lifespan, ideal for long-term industrial investment.

• Main Frame Material: Adopt Q355B steel warehouse grade main structure and Q235B/Q355B steel frame secondary components, classified as high strength steel storage to bear heavy loads and extreme weather pressure
• Frame Components: Heavy-duty welded H-section steel column and hot-rolled H-beam warehouse main beams, forming rigid H-section portal frame building for overall structural stability
• Corrosion Protection: Full Hot Dip Galvanized Corrosion Protection treatment for all steel members, resisting rust, chemical erosion and coastal salt spray
• Structural Performance: Professional Seismic And Wind Resistance Design, customizable to meet regional wind speed, snow load and seismic zone requirements worldwide
• Assembly Mode: Standardized Fast Assembly Bolt Connection, no on-site welding required, cutting installation time by 40% compared with traditional concrete buildings

The key advantage of our energy saving insulated sandwich panel steel warehouse lies in the flexible matching of roof and wall panels. We provide three mainstream sandwich panel types for thermal insulation, energy saving and fire prevention needs:

• EPS sandwich panel: Cost-effective lightweight option, excellent heat preservation, perfect for dry goods storage and low-budget warehouse projects
• Rock wool sandwich panel: Premium fire-rated material, core fireproof function, the preferred envelope for fire resistant steel warehouse and fireproof storage building
• PU / PIR sandwich panel: Top-tier energy-saving panel with ultra-low thermal conductivity, best for cold storage, temperature-controlled warehouses and high energy-efficiency demand scenarios

Matching metal roofing and wall cladding for auxiliary protection:

• Corrugated steel sheet: Classic wave-type metal sheet, high waterproof performance, widely used in conventional warehouse roofing
• Trapezoidal steel sheet: High-strength ribbed sheet, better load-bearing capacity, suitable for large-span roof systems and wall wind resistance reinforcement

• Ultra-long Service Life: Galvanized steel structure + anti-aging sandwich panels, guaranteed 50 year warehouse lifespan, low later maintenance cost
• Energy Saving & Thermal Insulation: Multiple energy saving insulated sandwich panel options reduce HVAC energy consumption by 30%-50% annually
• Professional Fire Safety: Rock wool panel equipped fire resistant steel warehouse meets Class A fire protection standard, safe for flammable goods storage as a standard fireproof storage building
• Fast On-site Construction: All components are prefabricated in factory, Fast Assembly Bolt Connection shortens project cycle by 50%
• Extreme Weather Resistance: Engineered Seismic And Wind Resistance Design adapts to hurricane, heavy snow and high-seismic regions
• Durable Structure: High strength steel storage configuration makes it a durable steel structure storage with strong load-bearing and impact resistance
• Cost-effective Investment: Lightweight steel structure reduces foundation cost; prefab design cuts labor and time cost, higher ROI than traditional buildings

Our steel portal frame warehouse is optimized for span flexibility. The large span steel warehouse and wide span metal warehouse series support column-free spans up to 60m, with customizable length and eave height. The open interior space eliminates structural obstacles, convenient for forklift operation, container loading/unloading, and large equipment storage, greatly improving warehouse space utilization.

• Industrial production: Factory workshop, production auxiliary warehouse, H-section portal frame building industrial plant
• Logistics storage: Freight terminal warehouse, distribution center, large-span cargo storage
• Special storage: Flammable material warehouse (fireproof storage building), temperature-controlled storage (energy saving insulated panel type)
• Agricultural use: Grain depot, livestock farm storage shed
• Commercial use: Supermarket logistics warehouse, exhibition temporary storage hall

As a professional manufacturer focusing on pre-engineered steel structures for over 20 years, we integrate R&D, production, design and export. All our durable steel structure storage and long lasting metal warehouse building products strictly follow ISO and international building standards. Whether you need a standard steel portal frame warehouse, fire-rated fire resistant steel warehouse, or energy-saving insulated storage building, we deliver customized complete steel warehouse package with stable quality, competitive price and full lifecycle after-sales support.

We provide Complete Turnkey One Stop Service and one stop storage building service covering the whole project lifecycle, which differentiates our complete steel warehouse package from ordinary suppliers:

• Custom structural design: Span, height, load, wind/seismic parameter customization based on local codes
• Material matching: Professional selection of EPS/Rock wool/PU-PIR panels and steel sheets per usage scenario
• Factory prefabrication: 100% component production in our factory as factory prefabricated warehouse standard
• Global shipping: Containerized packaging for the prefab steel warehouse kit, convenient for sea/land transportation
• On-site guidance: Overseas installation team support & detailed assembly manual for bolt connection construction
• After-sales support: 50-year structural warranty, lifetime technical consultation and spare parts supply

The company has obtained numerous international authoritative certifications, including CE certification (EN 1090-1), ISO 9001 quality management system certification, ISO 3834 welding quality system certification, ISO 14001 environmental management system certification, and ISO 45001 occupational health and safety management certification. We have also passed an SGS factory audit. From raw material selection, processing and manufacturing, quality inspection to surface coating, we implement strict quality control at every stage of production to ensure that products meet international standards before delivery.
