1-1/2″ x 1-1/2″ x 7 gauge (.188″ wall) square steel tubing is manufactured from ASTM A500 steel, a cold-formed carbon steel specification designed for heavy-duty structural applications. This hollow structural section (HSS) features a uniform square profile with a thick wall, offering exceptional strength, rigidity, and durability for demanding projects. Typically produced in Grade B, it provides excellent weldability, precise dimensional consistency, and reliable performance in high-stress applications.
Applications:
1-1/2″ square steel tubing (7ga) is commonly used in:
• Heavy-duty structural frames and supports
• Industrial machinery and equipment bases
• Gates, security structures, and railing systems
• Automotive and trailer chassis components
• Fabrication projects requiring high load capacity
• Structural bracing and load-bearing assemblies
Advantages:
• Exceptional strength: Thick wall (.188″) supports heavy loads and resists bending or deformation
• Durable construction: Suitable for heavy-duty structural and industrial applications
• Excellent weldability: Works well with MIG, TIG, and stick welding
• Versatile fabrication: Can be cut, drilled, and modified for custom projects
• Consistent quality: Manufactured for precise dimensions and reliable performance
Summary:
The 1-1/2″ x 1-1/2″ x 7 gauge ASTM A500 square steel tube is a heavy-duty structural material ideal for reinforced frames, supports, and load-bearing fabrication projects. Its thick wall, strength, and weldability make it suitable for demanding construction and industrial applications.

* All ‘value length’ and ‘value pack’ item measurements are subject to a “mill tolerance”. A product may be produced several thousandths of an inch, either over or under the stated thickness, and still be within “mill tolerance”. This does NOT apply to Cut To Size items. Those will be +.125″, -0.00″ tolerances.
