Galvanized Square Tube Characteristics

Galvanized coatings offer enhanced protective properties and corrosion resistance. The entire structure is composed of zinc, forming a dense quaternary crystalline layer. This crystalline layer acts as a barrier on the steel plate, effectively preventing corrosive elements from penetrating. The corrosion resistance comes from the strong barrier protective function of the zinc layer. When zinc acts as a sacrificial protector at the cut edges, scratches, and coating abrasions, it forms an insoluble oxide layer, which then serves as a barrier protective function.

Galvanized Square Tube Applications

Due to the galvanized treatment applied to square tubes, the application range of galvanized square tubes has been greatly expanded compared to plain square tubes. They are primarily used in curtain walls, construction, machinery manufacturing, steel construction projects, shipbuilding, solar panel supports, steel structure projects, power engineering, power plants, agricultural and chemical machinery, glass curtain walls, automotive undercarriages, and airports.
