Chinese factory Q355B high-quality steel portal structure steel structure warehouse

Product Introduction:

Precast steel structure warehouses are modern modular prefabricated buildings, offering a cost-effective, rapid-construction, robust, and durable industrial warehousing solution. All steel components are prefabricated in a standardized factory, and on-site assembly is done using only bolts, eliminating the need for on-site welding and significantly shortening the construction cycle and reducing construction costs. The product boasts a stable structure, wind and earthquake resistance, corrosion resistance, and durability, making it widely applicable to various scenarios such as industrial warehousing, logistics transit, factory warehouses, agricultural warehousing, and commercial warehouses. It is the preferred building type for overseas factory construction and warehousing investment projects.

Core Technical Parameters

Main Frame: High-strength hot-rolled H-beams (Q235B/Q355B), high load-bearing capacity and structural stability.
Roof and Wall Purlins: Hot-dip galvanized C/Z-shaped steel, rust-proof, corrosion-resistant, and not easily deformed.
Enclosure Materials: EPS foam sandwich panels, rock wool fireproof sandwich panels, PU polyurethane insulation panels, and single-layer color steel tiles are optional, thickness 50–150mm.
Building Specifications: Span 12–36 meters (large spans without central columns are possible), eaves height 4–12 meters, column spacing customizable.
Load Resistance: Maximum wind load resistance 1.2kN/㎡, snow load 0.3–1.0kN/㎡, adaptable to various regional climates.
Safety Performance: Meets seismic design requirements of 7–8 degrees, suitable for use in earthquake zones and areas with frequent rain and wind.
Surface Treatment: Multi-layer anti-rust and anti-corrosion paint/hot-dip galvanizing process, corrosion resistance life can reach over 20 years.
 

Applicable Scenarios:

Logistics and distribution warehouses, raw material/finished product warehouses for industrial enterprises, large production workshops, commercial warehousing centers, agricultural grain warehouses and livestock sheds, outdoor temporary storage, bonded warehouses, etc.

Product Attributes

Core Product Advantages

1. 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.

2. 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.

3. 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.

4. 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. 5. 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.
