Galvanized Square & Rectangle Tube 3-1/2 X 3-1/2 X 1/4 (.250 wall)

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. Metals Depot stocks many sizes in precut lengths, full mill lengths or we can hot dip virtually any size and quantity required for your welding or construction project.

Galvanized tubes can be cut, machined or welded by common methods used for regular steel, but adequate ventilation should be used to avoid inhalation of fumes when heated. Saw cut ends of our pre-cut lengths are not galvanized and should be treated with a cold galvanizing compound to maintain protection once your project is complete. Any holes drilled or welded areas should also be treated. All dimensions are before the galvanizing process.
