Galvanized Steel Tube - Square & Rectangle

Made from strong, low-carbon steel tube coated in zinc for rust protection, galvanized steel tubing offers a durable, corrosion-resistant material for a wide range of applications. The zinc coating helps protect against rust and extends service life compared to uncoated steel. It can be welded and fabricated, though proper precautions are needed when welding galvanized material. It is a highly versatile option, with square (equal sides) and rectangular (unequal sides) in stock for uniform strength or higher bending resistance, respectively, to meet the requirements of industrial applications and various metalworking projects.

From quick, accurate ordering to reliable delivery and shipping options, Competitive Metals is a trusted, top distributor of galvanized steel products and accessories to meet the needs of your planned projects. Contact us to speak with one of our knowledgeable representatives about your order.
 

Key Features and Benefits of Galvanized Steel Square and Rectangle Tubing

For applications in harsh, outdoor, or exposed environments, galvanized steel square and rectangle tubing demonstrates a high degree of corrosion resistance and a semi-smooth zinc finish to match the needs of your projects or assemblies. As a high-performance, versatile material option, galvanized steel tubes offer benefits that include:
  • Delivers heightened corrosion resistance
  • Offers low maintenance costs and repair needs
  • Features a longer lifespan than uncoated steel
  • Offers a practical balance of durability, corrosion resistance, and value
  • Can be cut, drilled, and fabricated for many applications—welding requires proper safety precautions and may require coating touch-up at the weld area
