Steel square tubing manufactured to ASTM A500 specifications is a structural hollow section designed for strength, dimensional accuracy, and weldability in structural and fabrication applications. This 1″ x 1-1/2″ x 11 gauge (.120″ wall) square steel tube features a rectangular profile that provides excellent load-bearing capability and resistance to torsional forces. ASTM A500 steel tubing is commonly produced from high-strength carbon steel and is suitable for both structural and mechanical uses where durability and consistency are required. The uniform wall thickness and clean corners make this tubing ideal for cutting, welding, and fabrication.
Applications:
ASTM A500 steel square tubing is widely used in structural, industrial, and fabrication applications, including:
• Structural framing and supports
• Equipment frames and machinery bases
• Racks, shelving, and storage systems
• Trailer frames and utility structures
• Architectural and ornamental steelwork
• General fabrication and welded assemblies
Advantages:
• High strength: ASTM A500 steel provides reliable load-bearing performance
• Consistent dimensions: Uniform wall thickness ensures predictable fabrication and fit-up
• Excellent weldability: Suitable for MIG, TIG, and stick welding processes
• Versatile profile: Rectangular shape offers strong resistance to bending and twisting
• Fabrication-friendly: Easily cut, drilled, and formed for custom applications
Summary:
The 1″ x 1-1/2″ x 11ga (.120″) ASTM A500 steel square tube is a strong, versatile structural material well suited for construction, fabrication, and industrial use. Its durable carbon steel composition, consistent dimensions, and excellent weldability make it a dependable choice for frames, supports, and custom steel assemblies where strength and reliability are essential.
