ISO9001 Certified Prefabricated Steel Structure Warehouse with 50 Years Usage Life and Large Span Design for Quick Assembly

Hello, are you preparing for your steel structure building?

We offer a comprehensive range of steel structures-including industrial plants, office buildings, warehouses, and mezzanines-providing a complete, one-stop service that covers everything from detailed design and factory prefabrication to logistics, on-site hoisting and installation, and lifelong maintenance.

If you already have construction drawings, please send them to us; our technical department will immediately verify the plans, calculate material requirements, and provide an accurate, tax-inclusive quote. If you do not have existing drawings, our team of senior structural design experts can create a full set of compliant construction drawings, renderings, and submission plans tailored to your specific needs. Simply provide the following project parameters, and we will customize a cost-effective, fully compliant project plan and set of drawings suited to local site conditions:

1. Project Location: Country, city, and site topography
   (flat ground, sloping terrain, or low-lying area near water).

2. Overall Building Dimensions: Total length × total width × eave height × ridge height
   (____mm × ____mm × ____mm × ____mm).

3. Local Wind Conditions: Basic wind pressure (kN/m²), prevailing maximum wind speed (km/h), and instantaneous gust speed (m/s).

4. Local Snow Conditions: Basic snow pressure (kN/m²), maximum annual snow accumulation (mm), and the extreme high/low temperature range for the project area.

5. Seismic Parameters: Seismic fortification intensity and seismic design grade for the project location.

6. Wall Enclosure Configuration: Will the exterior facade feature masonry (brick-concrete) enclosure walls? If masonry is required, custom wall heights: 1.0m / 1.8m / 2.0m / custom height.

7. Roof and wall insulation/fireproofing requirements: If thermal insulation and fire resistance are required, options include EPS color-steel sandwich panels, glass wool insulation, rock wool fireproof sandwich panels, or polyurethane (PU) insulation boards; if insulation/fireproofing is not required, single-layer anti-corrosive galvanized color-steel sheets may be used (single-layer sheets are lower in cost, significantly saving on the project budget).

8. Factory entrance/exit door configuration: Door type (sliding door / rolling shutter / hinged door), number of doors, dimensions per door: Width __mm x Height __mm.

9. Natural lighting and ventilation window configuration: Window type (thermal-break windows / skylight strips / louvered windows), number of windows, dimensions per window: Width __mm x Height __mm.

10. Internal lifting equipment configuration: Is an overhead crane to be installed? If yes, specify the crane's rated maximum load capacity (__ tons), lifting height to the top of the crane rail (__ meters), and crane span (__ meters).

11. Additional supporting requirements: Are provisions needed for drainage gutters, fire protection systems, floor load-bearing reinforcement, embedded electrical wiring, custom exterior facade painting, lightning protection reinforcement, or other supporting construction?

Main Frame: Utilizes national standard Q235B and Q355B high-strength hot-rolled/welded H-beams, offering strong load-bearing capacity, high structural rigidity, and resistance to deformation, meeting the requirements of heavy-duty warehousing loads.

Auxiliary Purlins: Hot-dip galvanized C/Z-shaped steel purlins, providing excellent rust and corrosion resistance, with a regular shape, suitable for installation with various enclosure panels.

Enclosure System: Optional 50-150mm EPS foam sandwich panels, rock wool fireproof sandwich panels, and PU polyurethane insulation panels are available, and can also be combined with single-layer color steel tiles to support multiple needs such as fire resistance, heat insulation, and sound insulation.

Building Specifications: Standard span 12-36m, supporting large-span designs without central columns; eaves height 4-12m, column spacing and overall dimensions can be customized as needed.

Weather Resistance: Maximum wind load 1.2kN/㎡, snow load 0.3-1.0kN/㎡, can be optimized according to the climate parameters of the project location.

Safety Level: Supports seismic fortification of 7-8 degrees, structurally stable and safe, suitable for complex working conditions such as multiple earthquake zones, strong winds, and blizzards.

Corrosion Protection: Double-layer anti-rust and anti-corrosion paint spraying or hot-dip galvanizing treatment, corrosion protection life can reach more than 20 years, significantly reducing later maintenance costs.

Connection Method: All bolted connection, convenient installation, stable structure, easy disassembly and relocation, and reusable.

Raw material and finished product warehouses of industrial enterprises, logistics and distribution transit warehouses, large production and assembly workshops, commercial warehousing centers, bonded warehouses, agricultural grain warehouses, breeding sheds, outdoor temporary storage, large equipment warehouses and other industrial and commercial scenarios.

• Large Column-Free Space, Extremely High Utilization: Supports large-span, column-free designs, providing open and unobstructed interior spaces. Facilitates forklift operations, shelving placement, and goods stacking, maximizing warehouse utilization and adaptable to various large-scale warehousing equipment.
• Rapid Construction, Significantly Reduced Construction Time: 90% of components are prefabricated in the factory, requiring only bolt assembly on-site. Compared to traditional brick-concrete construction, construction efficiency is increased by over 50%, enabling rapid completion and commissioning, helping customers shorten investment cycles and achieve profitability sooner.
• Robust and Durable, Long Service Life: Utilizes national standard high-strength steel with professional anti-corrosion and rust-proofing treatment. Excellent wind, rain, earthquake, and snow resistance. The main structure is designed for a service life of up to 50 years, resulting in extremely low maintenance costs.
• Thermal Insulation and Energy Saving, Suitable for All Seasons: High-quality insulated sandwich panels offer excellent heat insulation, sound insulation, and thermal insulation effects, effectively reducing indoor temperature control energy consumption. Warm in winter and cool in summer, suitable for complex climates with high temperatures, low temperatures, heavy rainfall, and strong winds year-round.
• Full-size Customization with Strong Adaptability: The building span, height, door and window positions, ventilation system, and drainage system can be customized according to the customer's site, purpose, and load requirements. It also supports the installation of overhead crane equipment up to 50 tons to meet the multi-functional needs of warehousing, production, and processing.
