Part#: SST212212250 Category
DESCRIPTION

2-1/2″ x 2-1/2″ x 3 gauge (.250″ wall) square steel tubing is manufactured from ASTM A500 steel, a cold-formed carbon steel specification designed for extremely heavy-duty structural applications. This hollow structural section (HSS) features a thick wall and robust square profile, providing exceptional strength, rigidity, and durability for high-load and industrial projects. Typically produced in Grade B, it offers excellent weldability, precise dimensional consistency, and reliable performance in demanding fabrication and construction applications.

Applications:
2-1/2″ square steel tubing (3ga) is commonly used in:
• Heavy-duty structural frames, columns, and supports
• Industrial machinery bases and equipment stands
• Gates, railings, and security structures requiring maximum strength
• Automotive and trailer chassis components
• Load-bearing fabrication and construction projects
• Structural bracing in commercial and industrial settings

Advantages:
• Maximum strength: Thick wall (.250″) supports very high loads and resists deformation
• Durable construction: Ideal for demanding structural and industrial applications
• Excellent weldability: Compatible 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 fit

Summary:
The 2-1/2″ x 2-1/2″ x 3 gauge ASTM A500 square steel tube is a premium heavy-duty structural material, perfect for reinforced frames, supports, and high-load industrial fabrication projects. Its thick wall, strength, and weldability make it suitable for the most demanding structural 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.
