2″ x 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 outstanding 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″ 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 performance
Summary:
The 2″ x 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.
