GAOERJI prefabricated steel structures are optimized by variable cross-section mechanics to provide excellent structural strength and super-large span space while reducing steel consumption by 30%. GAOERJI have established a complete closed-loop production line from design to manufacturing. As a source entity factory, we eliminate all middleman costs and directly provide you with superior ex-factory prices and more accurate delivery control.
Pre engineered steel structure is mainly used in large-scale logistics distribution centers, automated industrial production workshops, e-commerce bonded warehouses and large-span cold chain storage facilities.
professional software is used for mechanical modeling, and variable cross-section steel beams are used according to the force distribution. This refined design significantly reduces unnecessary steel consumption without reducing the safety factor, and saves about 30% of raw material costs for investors.
through the high-strength rigid frame system, to achieve a maximum of 90 m net span design. This eliminates the restrictions of internal pillars on forklift paths and automated sorting lines, and increases the utilization of flat space in logistics warehouses by more than 25%.
all cutting, punching and welding processes are done in the factory, with tolerances within 1mm. There is no need for secondary processing on site, only high-strength bolts are required for assembly, which shortens the construction period of the 10,000 square meter project by 50% compared with traditional buildings.
The vertical edge bite roof system is adopted to avoid the traditional punching and fixing method. This sealing structure solves the industry pain point of water seepage in large industrial plants, and ensures that precision equipment and inventory materials are always dry in high rainfall environment.
The wall and roof system can be integrated with glass wool or polyurethane sandwich panels, combined with heat-breaking cold bridge technology. This can reduce the energy consumption of indoor air conditioning by about 40%, which greatly reduces the energy expenditure cost of industrial logistics center in the long-term operation.
The PEB architecture allows lossless access to future business expansion. The reserved connection node enables the vertical extension or horizontal expansion of the warehouse without the need to stop work and rebuild, providing a high degree of flexibility for the investor’s asset appreciation.
| Technical Indicator Classification | Standard parameter description | Reference Specifications |
| Main structure type | Steel pipe truss / Steel box girder / Space frame | Optimization design based on span and load |
| Design load | 5.0 kN/m² (live load) | Meets AASHTO / Eurocode standards |
| railing height | Available in 1.1m–1.4m lengths. | Meets global pedestrian safety height requirements |
| Corrosion resistance lifespan | 30 years internal maintenance-free / 15 years external maintenance-free | ISO 12944 C5 level |
| Maximum deflection | L/500 (span ratio) | Ensure there is no vibration when pedestrians pass through. |
| Drainage system | Concealed internal drainage pipes | To prevent rainwater from directly eroding the bridge piers |
| Supporting systems | Integrated LED lighting, tactile paving, and drainage | Provides one-stop function integration |
For carriers that need to quickly deploy large transit centers. GAOERJI Pre engineered steel structure shortens the cycle from land acquisition to operation and solves the problem of loss of market opportunities due to slow construction.
for factories that need to expand production lines and install large cranes. The flexibility of the PEB structure addresses the need for lifting space for heavy equipment, while reducing the initial investment pressure on fixed assets through customized design.
for investors who pursue high volume ratio and high standard storage environment. Our column-free design solves the problem of tight shelf arrangement and waste of space, and significantly improves the rental income potential per unit area.
for the need to build a warehouse in line with international regulatory standards of the project side. GAOERJI offer solutions that meet stringent fire and structural safety standards, helping customers pass a variety of industry compliance reviews.
pre-sales to provide customized 3D deepening design and budget optimization services; after-sales stage, we provide each component with traceability code and up to 10 years of structural warranty. Commitment to 24-hour technical support, and provide a full set of assembly guide atlas at the project site.
the main structure of this product design service life of not less than 50 years. It is recommended to inspect the connections of the enclosure system every 3 years. Due to the use of high-quality anti-corrosion paint, the first overhaul period can be extended to more than 15 years under normal atmospheric conditions.
