China Ms Hollow Section Hot Dipped Galvanized Square Rectangular Tubes
Galvanized Square & Rectangle Steel Tube, is a A500 Grade that has been hot dipped in a zinc rich galvanizing process. Galvanized tubes are a lower cost alternative to stainless steel to achieve rust free protection for up to 30 years, while maintaining comparable strength with a durable surface coating.
Galvanized square steel tube is easy to weld, cut, form and machine. The galvanized coating also allows for improved corrosion resistance over other types of carbon steels. In addition, galvanized tubes are a lower cost alternative to steel to achieve rust free protection for up to 30 years, while maintaining comparable strength with a durable surface coating.
