We have a professional design team of about 20 people, with 10 years of design experience. We can meet your individual needs. We offer multi-type steel components, roof and wall panels, doors, and windows to choose from.
Utilizing premium quality steel materials, we implement the AWS-D1.1/D1.5 welding quality system and employ professional CWI welding inspectors to guarantee the high quality of our products.
Our operations feature 2 modern factories and 3 production lines covering a total area of 150,000 square meters. We can deliver a 5,000-square-meter warehouse within 30 days.
We offer step-by-step visual production updates with photos and videos covering every stage, from raw steel selection to fabrication. Video calls to inspect workshop processes in real-time are also available.
Advanced container and pallet packing safeguard the surface paint and zinc coating of the steel structures. To simplify on-site setup, we mark every single component sequentially according to the blueprints.
Comprehensive installation manuals and videos are provided. For complex projects, our engineers can be sent to your construction site to provide hands-on technical guidance and train local work crews.
We are a 23-year supplier of steel structure warehouses, steel workshop buildings, steel hangars, prefab steel gymnasiums, metal garage buildings, steel structure poultry houses, and other large-scale steel buildings. We provide one-stop steel structure services: design, fabrication, and installation guidance. We operate 2 modern factories in China with 4 advanced production lines equipped with complete manufacturing systems.
As a professional manufacturer of steel structure warehouses with over two decades of experience, we have successfully completed 3,520 projects totaling 17,600,000 square meters. Our team is committed to the design of heavy steel buildings, meticulous quality control, precise component manufacturing, and efficient structural assembly. We have built a comprehensive, highly efficient process for customer service, production, processing, installation, and after-sales support.
The cost is primarily determined by the building size (length, width, and height), local environment loads (wind speed, snow load, seismic demands), the type of insulation panels selected (PU, EPS, Rockwool, or Glasswool), and additional customized components like crane beams or specific window/door configurations.
Yes, we have a professional design team of around 20 experienced designers. We can create detailed custom blueprints, structural models, and component lists tailored to your application, whether for warehouses, workshops, sports gyms, or hangars.
We run 2 modern factories and implement the strict AWS-D1.1/D1.5 welding quality system. Additionally, certified CWI inspectors supervise all welding and fabrication phases, ensuring each structural component meets international quality standards before dispatch.
For a standard warehouse of around 5,000 square meters, we guarantee delivery within 30 days. The exact timeframe may vary depending on project complexity and the current capacity of our 4 production lines.
Absolutely. We provide complete installation instruction manuals, detailed numbering markings on every component, and step-by-step videos. Upon request, we can also dispatch our engineers to the construction site to guide assembly and train your local labor force.
