3″ × 3″ × 7 ga (.180″) Stainless Steel Square Tube is manufactured from austenitic Type 304 stainless steel and supplied in a standard mill finish. This square structural tubing features a 3-inch outside width and height with a 0.180-inch wall thickness, providing a strong balance of rigidity and weight. Type 304 stainless steel offers excellent corrosion resistance, durability, and formability, making this square tube suitable for structural, architectural, and general fabrication applications in indoor, outdoor, and mildly corrosive environments.

Applications:
Stainless Steel 304 square tube is commonly used in structural and fabrication applications, including:
• Structural framing and supports
• Architectural and decorative metalwork
• Handrails, guardrails, and safety barriers
• Equipment frames and machine bases
• Industrial platforms, racks, and supports
• Marine, outdoor, and food-service environments requiring corrosion resistance

Advantages:
• Corrosion resistant: 304 stainless steel resists rust and oxidation in many environments
• Strong and rigid: 7 ga (.180″) wall thickness provides excellent structural strength
• Square profile: Offers uniform strength and clean aesthetics for fabrication
• Weldable and formable: Easily cut, welded, and machined using standard stainless processes
• Mill finish: Clean, industrial appearance suitable for fabrication or further finishing

Summary:
The 3″ × 3″ × 7 ga (.180″) Stainless Steel 304 square tube is a durable, corrosion-resistant structural material designed for industrial, architectural, and general fabrication use. Its robust wall thickness, square profile, and reliable performance make it an excellent choice for framing, supports, and long-lasting stainless steel assemblies in demanding environments.
