Galvanized rectangular steel tubes are hollow rectangular tubes made of steel that are coated with a layer of zinc to prevent corrosion. The galvanizing process involves immersing the steel in a molten zinc solution, which creates a bond between the zinc and the steel, forming a protective layer on its surface.
These tubes are commonly used in construction and industrial applications such as building frames, scaffolding, fencing and other structural applications. They are strong and durable, and their galvanized coating provides excellent protection against rust and corrosion, making them ideal for use in outdoor environments.
