Product Description
A Large-sized Modular Steel Structure Warehouse is a high-capacity, efficient storage solution engineered for large-volume storage needs (1000-5000m²), integrating modular steel framing, heavy-load bearing, and large-span design. Manufactured with Q460/Q690 ultra-high-strength steel (main frames, trusses, columns) and 12.9-grade high-strength bolts, this product features large-span modular units (single span: 15-30m; module size: 5m×12m, 6m×15m) with a clear height of 8-12m. The steel frame adopts a space truss design with yield strength ≥460MPa, ensuring vertical load-bearing capacity ≥5kN/m², wind load resistance ≥1.0kN/m², and seismic intensity ≤8 degrees, with vertical deflection ≤L/600 (L=span length). Key features include 90% factory prefabrication (dimension error ≤±0.8mm) for on-site assembly in 30-60 days, integrated large-span roof systems (color steel sandwich panels + steel trusses) with waterproof and anti-corrosion treatment, and pre-installed large-scale logistics facilities (multiple roller shutter doors, loading docks, forklift channels, and overhead crane rails for 5-10 ton cranes). The surface is treated with cathodic electrophoresis + fluorocarbon coating, providing salt spray resistance ≥1500 hours and adapting to large industrial parks, logistics hubs, and port areas. It complies with GB 50017-2017, AISC 360, and EN 1993 standards, supporting customization of total area (up to 5000m²), span combination, and internal configurations (high-bay storage, automated racking systems). Professional services include wind tunnel testing, seismic performance simulation, BIM-based construction planning, on-site installation supervision, and post-construction acceptance.

Applications

Large-sized Modular Steel Structure Warehouses are ideal for large enterprises, national logistics companies, and e-commerce giants requiring high-capacity storage and efficient logistics operations. Certified by GB 50017-2017, AISC 360, and ISO 9001, they meet international large-span structural standards. Typical applications include national-level logistics distribution centers, e-commerce giant regional fulfillment centers (daily order volume ≥1000), large manufacturing enterprise raw material and finished product warehouses, port cargo storage facilities, and industrial park centralized storage hubs. They are particularly suitable for projects with large-scale storage demand, high logistics turnover, or automated storage requirements (e.g., AGV robot operation, automated racking systems). The modular design supports phased construction (e.g., first build 2000m², then expand to 5000m²) to match business growth. The minimum order quantity is 1 set (customized per project), with full tailoring based on area, span, height, and load conditions. Competitive project-based pricing and flexible delivery terms (45-90 workdays) support large-scale logistics infrastructure projects, while a monthly supply capacity of 15 sets ensures timely delivery. Customization options include corrosion-resistant upgrades (super duplex stainless steel components), fire-resistant coating (≥2.5 hours), and integration of automated storage and retrieval systems (AS/RS).
