Ribbed galvanized steel sheet spiral duct
This is a high-pressure duct that forms ribs between the flanges, significantly improving strength. It is used in cylindrical formwork for civil engineering and construction.
It has a high resistance to external pressure. The spiral hub and ribs serve as reinforcement. We also manufacture specified dimensions according to conditions such as on-site and transportation.
