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.

* 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.
