Product Description

Square 5/8" x 3' Long Square Tube 18ga (Galvanized & Black Powder Coated)

Our 5/8" square steel tube is a versatile and essential component for the ornamental fencing industry and general metal manufacturing. Built to withstand the unique challenges of the Texas climate, this 18-gauge steel tubing serves as a reliable backbone for a variety of structural and decorative projects. Available in classic galvanized or a high-durability black powder coat finish, its 3-foot length is specifically sized to reduce waste during the fabrication of shorter pickets or infill panels, providing a cost-effective choice for professionals who value efficiency on the job site.

Crafted from high-quality carbon steel, each 5/8" square steel tube features an industrial zinc coating that protects the metal from the inside out. For projects requiring enhanced aesthetics, the black powder coated variant features an advanced polyester finish baked over the galvanized core, delivering double the defense against rust and UV rays. The flat, uniform square surfaces are exceptionally easy to weld, drill, and bolt, allowing for seamless integration into existing fence systems or new custom builds.

Key Features & Benefits

  • Dual Finish Options: Select raw silver galvanized for utility or black powder coated for a sleek, premium look.
  • Optimal 18ga Thickness: Provides excellent structural integrity for ornamental applications without adding excessive weight.
  • Double Layer Protection: Black powder coated variant features a durable exterior shell over a zinc-galvanized core.
  • Ease of Fabrication: The uniform 5/8" profile and flat edges make this tubing ideal for clean welding and clean cutting.
  • Texas-Proven Durability: Built to handle high heat and seasonal moisture, keeping your fence lines straight and secure.

Applications

  • The 5/8" square steel tube is commonly utilized in various commercial and residential settings, including:
  • Ornamental Fencing: Perfect for vertical pickets in residential perimeters or school security fences.
  • Custom Gate Inlays: Creating decorative and secure patterns within larger gate frames.
  • Construction Sites: Used for temporary safety railings and site-specific structural supports.
  • Furniture Manufacturing: Fabricating industrial-style shelving, table legs, and modern interior decor.
  • Infrastructure Protection: Creating protective barriers around HVAC units or specialized utility equipment.

This product is part of our extensive range of metal components designed for the Texas tradesman. While this specific listing covers the 3-foot length, we offer a variety of sizes and gauges to meet any engineering requirement. For those looking for a complete look, this tubing is compatible with our wide selection of Ornamental Fencing panels.
