GAOERJI offers high-strength, modular 40’×40’ steel-framed buildings. Rigorous structural analysis and precision fabrication ensure that every square inch meets industrial-grade load-bearing standards. As a source-manufacturing factory, GAOERJI operates a full-industry-chain production line, eliminating intermediate trading links. By adopting a direct-from-manufacturer supply model, we provide you with highly competitive ex-factory prices and a more efficient production and delivery cycle.
GAOERJI 40×40 steel structure buildings are widely used in agricultural warehousing, small-scale production workshops, commercial exhibition halls, and equipment parking centers.
Tekla software is used for three-dimensional modeling, and the processing accuracy of components is controlled within 2mm, ensuring that the bolt holes are completely aligned during on-site splicing, thus greatly reducing the cost of manual adjustment.
the main steel components are treated by full hot-dip galvanizing process, and the coating thickness reaches more than 80 microns. Even in humid or acid-base environment, it can still maintain no serious corrosion for 50 years.
The 40 × 40 building layout supports the internal column-free design, and the doors and windows are flexibly opened according to actual needs to meet the special spatial layout of different cargo access and equipment installation.
Based on structural mechanics calculations, the overall wind resistance level of the building can reach 12 or more, with superior seismic performance, which can effectively protect internal assets and equipment safety in extreme climates.
all components are completed in the GAOERJI factory welding, drilling and spraying, on-site only need bolted connection, reduce welding operations, significantly reduce the labor cost of on-site installation.
building exterior walls and roof panels using high-strength color steel plate, with self-cleaning function, without regular painting, compared to the traditional brick-concrete structure can reduce the maintenance cost of about 30% per year.

need to quickly build high-quality warehouses to store food, feed or large agricultural machinery, the pursuit of moisture-proof, rat-proof and mildew-proof storage environment, to ensure the safety of agricultural assets.
seek cost-controllable workshop expansion plan, requiring no column interference in the workshop to arrange production lines, and have good seismic capacity to support the operation of various equipment.
small and medium-sized transit warehouses that need to be put into use quickly have specific requirements for the net height of the building and the width of the entrance and exit, and need to meet high local safety standards.
looking for a reliable steel structure supplier, need the manufacturer to provide Tekla standard construction drawings and detailed structure calculation, in order to successfully pass the local project acceptance.
the foundation shall be poured according to the layout of embedded parts provided by the GAOERJI to ensure that the deviation of anchor bolt spacing is less than 5mm, so as to lay a solid foundation for subsequent installation.
install the rigid frame column in strict accordance with the sequence of construction drawings, use high-strength bolts for connection, and ensure that all node bolts meet the specified pre-tightening torque requirements.
check whether the bolts of key nodes are loose once a quarter. If the surface paint layer is found to be damaged, repair it in time to prevent rust from spreading to the inside.
it is strictly forbidden to hang heavy objects exceeding the design load on the steel beam roof truss. if cranes or heavy equipment need to be added, they must be recalculated and reviewed by professional structural engineers.
