Frequently Asked Questions

What are the primary applications for these steel structures?
These structures are ideal for large-scale workshops, warehouses, plants, supermarkets, entertainment centers, and high-rise building projects.
What is the expected lifespan and warranty of the building?
The steel structures are designed for long-term durability, coming with a 50-year warranty period.
Which materials are used for the main frame?
The main frame typically uses high-quality H beams made from Q235B, Q345B, or Q355 steel, depending on the load requirements and customer specifications.
How is the surface of the steel treated for rust prevention?
The surface is treated with either two layers of high-quality anti-rust painting or a hot-dip galvanizing process to ensure maximum corrosion resistance.
What information is needed to get a custom design?
To provide a custom design, we require dimensions (length, width, height), local environmental loads (wind, snow, rain), and specific requirements for doors and windows.
What are the main advantages of this prefabricated system?
Key benefits include lower construction costs, high safety performance, fast assembly and dismantling, and an environmentally friendly, non-pollution manufacturing process.
