Galvanized Square Tube
Galvanized Square and Rectangle Steel Tube is manufactured to A500 and A513 grade standards and hot-dip galvanized in a zinc-rich bath for superior corrosion resistance. This treatment makes it a strong, long-lasting solution for structural, framing, and support applications.
Galvanized Square Tube offers a cost-effective alternative to stainless steel, providing up to 30 years of rust-free performance in outdoor and industrial settings. It is ideal for fencing, handrails, framework, and other exposed structural elements.
Hot-dipped galvanized (HDG) steel tubing is recognized by its spangled surface finish—a crystallization pattern that indicates a robust zinc coating. This layer enhances the tube’s resistance to weathering, impact, and chemical exposure.
Galvanized Square Tube maintains the structural strength of carbon steel while adding a durable surface coating for long-term protection. This makes it ideal for industrial frameworks, commercial enclosures, and load-bearing installations.
