4″ x 4″ x 14 gauge (.083″ wall) square steel tubing is manufactured from ASTM A500 steel, a cold-formed carbon steel specification designed for light- to medium-duty structural applications. This hollow structural section (HSS) features a large square profile with a moderate wall thickness, providing a balance of strength and weight. Typically produced in Grade B, it offers excellent weldability, dimensional consistency, and reliable performance for fabrication and construction projects.
Applications:
4″ square steel tubing (14ga) is commonly used in:
• Structural frames, supports, and columns
• Gates, fencing, and railing systems
• Equipment enclosures and protective guards
• Furniture and architectural metalwork
• DIY and fabrication projects
• Light- to medium-duty commercial and industrial structures
Advantages:
• Large profile: Provides increased surface area and structural presence
• Balanced strength: Suitable for light- to medium-duty applications
• Excellent weldability: Works well with MIG, TIG, and stick welding
• Easy fabrication: Can be cut, drilled, and modified as needed
• Consistent quality: Manufactured for uniform dimensions and reliable fit
Summary:
The 4″ x 4″ x 14 gauge ASTM A500 square steel tube is a versatile and economical material for light- to medium-duty structural and fabrication projects. Its larger size combined with manageable weight makes it ideal for frames, supports, and architectural applications.
