We specialize in customized large-span steel warehouse buildings with a span range of 12m to 100m span. The Large Span Clear Space Warehouse design eliminates redundant middle columns, maximizing internal usable space and meeting the needs of large equipment storage, bulk cargo stacking, and large-scale production operations. The multi span warehouse structure is suitable for super-large-area warehouse parks, which can divide functional areas reasonably and realize centralized management of storage, sorting, and distribution. In addition to the innovative Multi Story Warehouse Design makes full use of vertical space, solving the space bottleneck of limited land resources and improving storage capacity per unit area.
The entire building frame strictly adopts Q235B Q355B steel frame dual material configuration, and the Q355B steel warehouse has excellent compression resistance, wind resistance, and seismic performance, adapting to various extreme weather and complex geological environments. The main load-bearing components use welded H section steel column and hot rolled H beam warehouse standard parts, which have undergone multiple precision processing procedures such as rust removal, galvanization, and anti-corrosion coating, with a service life of more than 50 years. All steel materials comply with international industrial standards, with stable mechanical properties and strong structural bearing capacity.
As a professional pre engineered steel storage supplier, we implement full factory prefabricated production for all warehouse components. All steel frames, sandwich panels, and accessories are pre-processed, pre-cut, and pre-assembled in the factory, avoiding on-site cutting, welding, and other complicated operations. The whole building adopts Fast Assembly Bolt Connection technology, which simplifies the on-site construction process, shortens the construction cycle by 60% compared with traditional concrete buildings, and effectively saves labor and time costs for customers.
This prefab warehouse kit is a veritable Cost Effective Economic Solution for global warehouse construction. The modular production and standardized installation reduce comprehensive construction and maintenance costs. At the same time, the Modular Expandable Storage design supports free expansion, splitting, and transformation of the warehouse area and structure according to business development. Customers can expand the storage space or adjust the functional layout at any time without large-scale demolition and reconstruction, greatly improving the flexibility and reuse rate of the building.
The wall and roof of the sandwich panel steel warehouse adopt high-quality insulated sandwich panels, with excellent heat insulation, heat preservation, waterproof, and fireproof performance. It can effectively adjust the internal temperature of the warehouse, reduce air conditioning and ventilation energy consumption, and create a constant-temperature, dry, and safe storage environment for goods. The panel has tight splicing, strong weather resistance, no water leakage, and no aging, which can adapt to long-term outdoor use in various climates.
With flexible structure, stable performance, and strong practicability, our modular steel warehouses are widely used in multiple fields. It is the preferred building solution for logistics park warehouse steel projects, suitable for logistics distribution centers, transit warehouses, and freight storage yards. At the same time, it is also widely used as industrial factory warehouses, production workshops, commodity storage warehouses, super-large cargo storage centers, and multi-story comprehensive storage buildings, covering the storage and production needs of manufacturing, logistics, e-commerce, trading, and other industries.
- Full Customization: Free customization of span, height, layer number, and functional layout to meet personalized construction needs of different customers
- Strict Quality Control: Supported by 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 system certification
