Product Description

 

Product Description

Galvanized Square & Rectangle Steel Tube, is ASTM A36\A572 Gr50 steel tube 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 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. 
  Hot-dipped galvanized perforated square tube is an excellent candidate for most processing techniques. Welding, torching, or abrasive sawing galvanized steel is not recommended without proper protection and adequate ventilation. Galvanized perforated square tubes are hot rolled steel, or mild steel, tubes that have been punched and dipped into a molten zinc coating process. Hot-dipped galvanize (HDG) can be identified by its crystallization pattern, also known as "spangle" on the surface of the material. Great corrosion resistance, excellent candidate for outdoor use or exposed environments. Common applications include shelving, brackets, outdoor signs, and adjustable posts due to its telescoping size options.
