This is a common size for square pipes.The steel pipe has undergone the galvanization process before being formed into a square shape. Pre-galvanizing involves coating the steel with a layer of zinc to provide corrosion resistance and ensure the durability of the pipe.The pre-galvanized coating provides excellent corrosion resistance, making the pipe suitable for outdoor and exposed environments.20*20 pre-galvanized steel pipes are commonly used for structural support and framing in construction and engineering projects.
