1-1/2″ x 1-1/2″ x 11 gauge (.120″ wall) square steel tubing is manufactured from ASTM A500 steel, a cold-formed carbon steel specification designed for medium- to heavy-duty structural applications. This hollow structural section (HSS) features a uniform square profile with a thicker wall, offering enhanced strength, rigidity, and durability. Typically produced in Grade B, it provides excellent weldability, precise dimensional consistency, and dependable performance for demanding fabrication and construction projects.
Applications:
1-1/2″ square steel tubing (11ga) is commonly used in:
• Reinforced frames, supports, and brackets
• Medium- to heavy-duty furniture and industrial shelving
• Gates, railings, and security structures
• Equipment enclosures and protective guards
• Automotive fabrication and trailer components
• General industrial and commercial metalwork
Advantages:
• Increased strength: Thicker wall (.120″) supports heavier loads and resists bending
• Durable construction: Suitable for medium- to heavy-duty structural applications
• Excellent weldability: Compatible with MIG, TIG, and stick welding
• Versatile fabrication: Can be cut, drilled, and modified easily
• Consistent quality: Manufactured for uniform dimensions and reliable fit
Summary:
The 1-1/2″ x 1-1/2″ x 11 gauge ASTM A500 square steel tube is a durable and versatile solution for medium- to heavy-duty structural and fabrication projects. Its thicker wall, combined with excellent weldability and strength, makes it ideal for reinforced frames, supports, and load-bearing assemblies.
