3/4″ x 3/4″ x 11 gauge (.120″ wall) square steel tubing is manufactured from ASTM A500 steel, a cold-formed carbon steel specification designed for structural and mechanical applications. This hollow structural section (HSS) features a compact square profile with a thicker wall than lighter gauges, providing increased strength, rigidity, and durability. Commonly produced in Grade B, this tubing offers excellent weldability, consistent dimensions, and dependable performance in more demanding applications.
Applications:
3/4″ square steel tubing (11ga) is commonly used in heavier-duty and precision fabrication projects, including:
• Reinforced frames, supports, and brackets
• Furniture requiring added strength and rigidity
• Gates, railings, and security structures
• Equipment supports and protective guards
• Automotive fabrication and custom builds
• Industrial and commercial metalwork
Advantages:
• Increased strength: Thicker wall (.120″) provides greater load capacity and rigidity
• Durable construction: Resists bending and deformation under stress
• Excellent weldability: Suitable for MIG, TIG, and stick welding
• Versatile fabrication: Easy to cut, drill, and modify
• Consistent quality: Manufactured for uniform dimensions and reliable performance
Summary:
The 3/4″ x 3/4″ x 11 gauge ASTM A500 square steel tube is a strong and durable solution for applications requiring additional structural integrity in a compact size. Its thicker wall, combined with excellent weldability and versatility, makes it ideal for reinforced frames, supports, and demanding fabrication projects.
