Galvanized Steel Rectangle Tubing

1/4'' Thick, 3'' x 4'' x 24', Galvanized Steel A500

A strong, corrosion-resistant rectangular steel section built for medium- to heavy-duty structural, fabrication, and industrial projects. Manufactured from ASTM A500 galvanized steel, this tube combines robust strength with long-lasting rust protection, making it ideal for both indoor and outdoor applications.

ASTM A500 Structural Strength – Engineered to deliver consistent performance and reliable load-bearing capacity for medium-duty framing and fabrication.

Galvanized Zinc-Coated Finish – Protects against corrosion and environmental wear, ensuring durability in outdoor or moisture-prone settings.

1/4 in. Wall Thickness – Heavy-duty walls provide rigidity and strength for structural reinforcement, supports, and fabricated assemblies.

Precision 3 in. x 4 in. Profile – Accurate dimensions deliver stability and uniformity for framing, bracing, and custom metalwork.

24 ft. Length – Supports long, continuous spans with fewer joints, enhancing structural integrity and installation efficiency.

Excellent Weldability & Fabrication Performance – Compatible with MIG, TIG, and stick welding; easily cut, drilled, and formed for custom project requirements.

Reliable ASTM-Certified Quality – Produced under strict standards to ensure consistent performance across commercial, industrial, and agricultural uses.
