Price range: $5.93 through $20.55

Part#: SST1111 Category
DESCRIPTION

1″ x 1″ x 11 gauge (.120″ wall) square steel tubing is manufactured from ASTM A500 steel, a cold-formed carbon steel specification designed for structural and heavy-duty applications. This hollow structural section (HSS) features a compact square profile with a thicker wall, providing increased strength, rigidity, and durability compared to lighter gauges. Typically produced in Grade B, it offers excellent weldability, precise dimensional consistency, and dependable performance for more demanding fabrication and structural projects.

Applications:
1″ square steel tubing (11ga) is commonly used in:
• Reinforced frames, supports, and brackets
• Heavy-duty furniture and industrial shelving
• Gates, railings, and security structures
• Equipment enclosures and protective guards
• Automotive fabrication and custom builds
• Industrial and commercial metalwork requiring extra strength

Advantages:
• Increased strength: Thicker wall (.120″) supports heavier loads and resists bending
• Durable construction: Ideal for structural and high-stress 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″ x 1″ x 11 gauge ASTM A500 square steel tube is a strong, durable solution for light- to medium-duty structural projects requiring extra rigidity. Its thicker wall, combined with excellent weldability and versatility, makes it ideal for reinforced frames, supports, and demanding fabrication applications.

* Prices subject to change without notice due to the Metals Market fluctuations. | 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”. Since we cut the material specifically for your order, they follow these tolerances: Length: +0.125″ / -0.062” – Please note that during cutting, the blade removes about 1/16″ of material (kerf). This is a normal part of the process and is already considered within the stated tolerances.
