Q: What is the hardness range of DX51D?
A: The HV hardness is typically between 70-130, offering moderate hardness that balances machinability and structural stability.
Q: How is the bending performance of DX51D?
A: It can achieve 180° cold bending without cracking, exhibiting excellent cold forming performance and capable of being processed into various complex building profiles.
Q: What are the core applications of DX51D in the construction field?
A: Primarily used for roofing panels, wall cladding, cold-formed steel profiles, drainage ditches, ventilation ducts, and steel structure cladding systems.
Q: Can DX51D be used for load-bearing structural components?
A: Only suitable for secondary load-bearing components such as purlins and wall beams. Higher strength steel grades are required for primary load-bearing structures.
Q: What are the advantages of DX51D roofing panels?
A: Lightweight and high-strength, easy to install, and with good corrosion resistance, suitable for large-span building roofs such as industrial plants and warehouses.
