2″ x 2″ Mild Steel Square Tube For Projects
This 2″ x 2″ square steel tube features a 1/8″ wall (11 gauge) and is made from A-36 mild steel. Best for: budget-conscious builders needing solid structural support in frames, rails, or shoe-rack frames. Choose this if you prioritize affordability and proven steel strength. Better for projects requiring machining or welding with common tools. Caution: heavier than aluminum options; plan for additional weight in bulky constructions.
BENECREAT 11.9x2x2 Inch Aluminum Square Tubing
This aluminum square tubing measures 11.9 inches long with a 5×5 cm cross-section and a 34×34 mm inner dimension. Made from 6061 aluminum alloy, it offers excellent corrosion resistance and light weight for DIY frames, decor, and lightweight structural projects. Best for: hobbyists seeking easy fabrication and a corrosion-resistant profile. Better for portable, carry-along builds. Caution: shorter length per piece may require more connections for larger projects.
Allstar 1in x 2in Steel Tubing, 7.5ft
This Allstar steel tubing features a 1″ x 2″ rectangular profile with a thickness of about .120″ and a total length of 7.5 feet. Best for: longer framing runs and structural members that need moderate strength without excessive weight. Choose this if you need extended spans in steel framing. Limitation: rectangular profiles can complicate some corner joints compared to square tubes.
Allstar Square Mild Steel Tubing 2in x .083in x 7.5ft
This square mild steel tube offers a 2″ x 2″ cross-section with an approximate wall thickness of .083″ and a 7.5-foot length. Best for: mid-weight frames and supports where rigidity matters but weight must be controlled. Better for projects needing quick assembly with standard steel stock. Caution: thinner wall compared to heavier-gauge options may limit load-bearing capacity for high-stress applications.
Rocaris 2×2 Steel Square Tube
Rocaris offers a 2″ x 2″ steel square tube with a 1/8″ wall along a 12″ length, suitable for compact, lightweight framing or decorative hardware. Best for: quick projects needing a short, sturdy piece. Better for small builds or finishing touches. Limitation: short length means joints are more frequent for larger frames.
Buying Guide
What material should you choose?
Mild steel tubes provide strength and lower cost, ideal for permanent installations or environments with minimal corrosion risk. Aluminum tubes reduce weight and resist corrosion, making them great for portable projects and outdoor decor. Consider your project’s environment and the required load when choosing between steel and aluminum.
How thick should the wall be?
Wall thickness affects strength and weight. A 1/8″ wall (11 gauge) is common for general framing and moderate loads. Thicker walls are better for heavier loads or longer spans, while thinner walls save weight and cost but may limit load capacity.
Which length is best?
Longer pieces reduce the number of joints but add weight and handling difficulty. Shorter pieces provide flexibility for complex shapes and easier cutting, but may require more connections. Plan your build layout to balance joints and strength.
How do I join these tubes?
Common methods include welding, mechanical fasteners, or bolting sections together. Aluminum tubes weld differently from steel; verify compatibility with your tools and fasteners. If you’re unsure, choosing a model with standard dimensions simplifies shop work.
Which option is best for beginners?
Aluminum square tubing from BENECREAT is generally easier to handle and cut, with good corrosion resistance. For budget-focused projects, the 2″ x 2″ mild steel tube offers solid strength at a lower price point, suitable for first-time fabrications.

FAQ
- Q: Is 2×2 square tubing suitable for outdoor projects? A: Aluminum options offer superior corrosion resistance for outdoor use, while steel may require protective finishes.
- Q: Can I weld 2×2 square tubes of these materials? A: Steel tubes can be welded with standard process; aluminum requires different weld approaches and preparation.
- Q: Which is lighter, steel or aluminum 2×2 tubes? A: Aluminum is typically lighter than mild steel for the same cross-section.
- Q: Are these tubes suitable for furniture frames? A: Yes, particularly the aluminum option, which provides good strength-to-weight ratio for decorative or functional frames.
- Q: How do I measure wall thickness on a square tube? A: Wall thickness is the distance between the outer and inner surfaces; confirm the specification (e.g., 1/8″ or 8mm) before purchasing for your fitment.
