scaffolding galvanized steel pipe

48.3mm Galvanized Steel Scaffolding Pipes are designed for pipes&coupler scaffolding.The pipes have hot-dipped galvanized surfaces finish so as to provide excellent appearance with sufficient durability in such applications where salty air or long-term weather exposures are inevitable.
