A strong, corrosion-resistant structural steel section designed for demanding fabrication, construction, and industrial applications. Made from ASTM A500 galvanized steel, this rectangular tube combines heavy-duty strength with long-term rust protection, making it ideal for both indoor and outdoor structural use.
ASTM A500 Structural Strength – Built to deliver consistent mechanical performance and high load-bearing capability for medium- to heavy-duty applications.
Galvanized Zinc-Coated Finish – Provides superior corrosion resistance, extending longevity in moisture-prone, outdoor, or industrial environments.
1/4 in. Wall Thickness – Thick, durable walls designed to withstand high stress and structural loads while maintaining excellent rigidity.
Precision 3 in. x 5 in. Profile – Accurate dimensions ensure stability, uniformity, and smooth integration into framing, reinforcement, or fabricated assemblies.
24 ft. Length – Offers long, continuous spans with fewer joints, improving overall structural integrity and installation efficiency.
Excellent Weldability & Fabrication Performance – Easily welded, cut, drilled, and formed; compatible with standard fabrication processes.
Reliable ASTM-Certified Quality – Manufactured under strict standards to ensure consistent performance across commercial, industrial, and agricultural applications.
