Different from traditional building structures, our clear span warehouse realizes full column free storage space without intermediate supporting columns. The maximum span can reach 60 meters or more, completely eliminating space obstacles.

This open layout maximizes internal usable area, facilitates flexible placement of shelves, large machinery, and bulk goods, and supports free movement of forklifts and transport vehicles. It is perfectly suitable for large-scale cargo stacking, automated storage systems, and multi-scenario industrial storage needs, greatly improving warehouse operation efficiency.

The main load-bearing structure adopts standardized welded h section steel column and integral heavy duty steel frame, made of high-grade Q355B/Q235B high strength steel storage materials. All steel components undergo precision welding, shot blasting rust removal, and hot-dip galvanizing/paint anti-corrosion treatment.

The integral frame features high rigidity, strong seismic resistance, wind resistance, and load-bearing capacity, effectively resisting extreme weather such as strong winds, heavy snow, and storms. The service life of the main steel structure can exceed 50 years, realizing long-term stable operation of the warehouse.

We adopt high-quality sandwich panel steel warehouse dedicated wall and roof panels, which are the core enclosure materials for industrial steel warehouses. The panel consists of double-layer galvanized color steel sheets and high-density core materials, with integrated functions of heat insulation, waterproofing, sound insulation, and decoration.

The modular splicing structure is easy and fast to install, with tight seams and no thermal bridges, effectively avoiding air leakage and heat loss.

Our insulated warehouse panel is specially designed for temperature-sensitive storage scenarios. The core materials include PU, PIR, and EPS optional materials, with excellent thermal insulation and heat preservation performance.

It can effectively isolate external temperature changes, maintain stable internal warehouse temperature, reduce energy consumption of air conditioning and temperature control equipment, and create a constant-temperature storage environment for ordinary industrial materials, electronic products, and packaging materials.

For food, medicine, fresh products, and low-temperature storage needs, we provide professional cold storage warehouse panel. This panel adopts high-density closed-cell thermal insulation core material, with ultra-low thermal conductivity and strong anti-condensation ability.

It can stably maintain low-temperature environments from -40℃ to 10℃, effectively preventing cold air loss and external heat penetration. It is the exclusive supporting panel for industrial cold storage warehouses and low-temperature logistics warehouses, ensuring the freshness and storage safety of cold chain goods.

All customized panels support fire resistant upgrade configuration. We provide rock wool, glass wool, and PIR fireproof core materials, which have passed international fire rating tests, reaching Class A fireproof standard.

The fire resistant panels can effectively block flame spread, resist high-temperature combustion, and delay fire expansion. Combined with the incombustible all-steel structure of the warehouse, it builds a comprehensive fire safety barrier, greatly improving the safety level of warehouse storage goods and factory assets, meeting the strict fire protection requirements of industrial and commercial warehouses in various countries.

This integrated steel warehouse solution is widely used in industrial factory storage, logistics freight warehouses, food cold chain storage warehouses, constant-temperature warehouses, chemical raw material storage, supermarket distribution centers, and large commercial storage bases. Whether it is ordinary room-temperature storage, constant-temperature heat preservation storage, or low-temperature cold storage, it can provide stable and professional building support.

We provide one-stop overseas engineering services including free design drawing, customized scheme optimization, factory prefabrication, professional packaging and transportation, on-site installation guidance, and long-term after-sales maintenance. All products are exported in line with international standards, supporting project customization of different scales, and providing reliable high-quality steel warehouse solutions for global customers.
