A500 hot rolled (HR) steel rectangular tubing is a structural-grade carbon steel product manufactured to ASTM A500 specifications for strength, durability, and consistent performance. The 3″ × 6″ × 11 gauge (0.120″) HR steel rectangular tube features a heavy-wall hollow structural section (HSS) with a wide rectangular profile designed for increased strength, rigidity, and load-bearing capacity in demanding structural applications. Its larger profile provides excellent stability and load distribution, making it well-suited for heavy-duty fabrication and construction projects. This material has a raw hot rolled mill finish and may exhibit a dark surface with mill scale, typical of structural carbon steel.

Applications:
A500 steel rectangular tubing is commonly used in structural and fabrication applications, including:
• Heavy structural frames and support systems
• Equipment bases and industrial machinery structures
• Trailer frames, truck beds, and transport equipment
• Construction and infrastructure projects
• Fencing, gates, and safety barriers
• Custom fabrication requiring strength and stability

Advantages:
• High strength: 0.120″ wall thickness provides excellent load-bearing capacity
• Wide profile: 3″ × 6″ section improves stability and load distribution
• Weldable: Suitable for MIG, TIG, and stick welding
• Machinable: Can be cut, drilled, and fabricated with ease
• Consistent dimensions: Uniform shape for precise structural use
• Durable performance: Built for demanding industrial applications

Summary:
The 3″ × 6″ × 11 gauge (0.120″) A500 HR steel rectangular tube is a strong and reliable structural material designed for heavy-duty applications. Its wide profile, thicker wall, and excellent weldability make it an ideal choice for demanding fabrication, construction, and industrial projects.
