 Characteristics of galvanised square steel posts

custom size galvanized square tubing, cold-rolled strip steel double-sided pre galvanized, with strong adhesion of zinc layer. The surface zinc layer forms a dense protective film, forming a stable quaternary crystalline protective structure to isolate corrosive substances such as water vapor. Greatly extending the service life of various sizes galvanized rectangular tube.

When the pipe has cuts or scratches, the zinc layer can act as a sacrificial protective layer, generating an oxide protective layer to prevent corrosion from spreading. So when the pipe is damaged, the zinc layer still has a protective effect. This has led to the widespread use of galvanized square tube for construction with long lifespan and affordable prices.
