1″ x 3″ x 11ga (.120″)*
A500 steel rectangular tubing is a structural-grade carbon steel product manufactured to ASTM A500 specifications for strength, durability, and consistency. The 1″ x 3″ x 11 gauge (.120″) steel rectangular tube features a hollow structural section (HSS) with a thicker wall for increased strength and rigidity, making it well-suited for heavy-duty structural and fabrication applications. It offers a uniform shape and straight profile for precise fit-up and reliable performance. This material has a raw, non-galvanized mill finish and may exhibit a dark surface with mill scale, typical of standard hot-rolled steel.
Applications:
A500 steel rectangular tubing is commonly used in structural and fabrication applications, including:
• Structural frames and supports
• Equipment bases and heavy-duty machinery structures
• Trailers, racks, and enclosures
• Fencing, gates, and railing systems
• General fabrication and welding projects
• Automotive and industrial components
Advantages:
• High strength: .120″ wall thickness provides added durability and load capacity
• Weldable: Suitable for MIG, TIG, and stick welding
• Formability: Can be cut, drilled, and machined with ease
• Consistent dimensions: Uniform shape and wall thickness for precise applications
• Versatile use: Ideal for structural, mechanical, and general-purpose fabrication
Summary:
The 1″ x 3″ x 11 gauge (.120″) A500 steel rectangular tube is a strong, durable, and versatile structural material designed for demanding applications. Its thicker wall, consistent profile, and excellent weldability make it an ideal choice for projects requiring increased strength and long-term reliability.
