Hot Rolled Steel 2×2 Square Tubing — 36″ Length
High-strength carbon steel forms the core of this 2″ x 2″ square tubing. With a 1/4″ wall, it provides robust structural support suitable for frameworks, machine bases, and architectural elements. The tubing is ready for modification, enabling welding, drilling, and cutting to fit custom designs. Applications include equipment housings, frames for industrial carts, and lightweight yet durable structural members for hobbyist and professional projects.
Zonon 2″ x 2″ Square Hot Rolled Steel Tube
Made from A35 steel through a hot rolled process, this 2″ x 2″ square tube emphasizes longevity and load-bearing potential. Its design targets heavy-duty applications, indoor or outdoor environments, and projects requiring good texture and sealing. Practical uses include frames for agricultural equipment, protective guards, and modular assembly systems where resistance to deformation after fabrication is important.
OnlineMetals Aluminum 6063-T52 Square Tubing, 2″ x 2″
This aluminum square tubing combines a 2″ x 2″ profile with a 1/8″ wall thickness, delivering a strong yet lightweight structural option. The 6063-T52 alloy provides excellent corrosion resistance and good machining characteristics. It is well suited for architectural framing, railing systems, machine guards, and modular framing assemblies used in both industrial and DIY settings.
1/4″ Wall x 2″ x 2″ Steel Square Tube
This option emphasizes uniform 2″ x 2″ square tubing with a 1/4″ wall. Cut-length tolerances are listed at +/- 1/8″, providing predictable behavior in fabrication and assembly. It suits general steel framing, fabrication benches, and light-to-medium duty structural components where consistent wall thickness is critical for performance.
Blulu Perforated 1-1/4″ x 48″ Square Tubing
Although this item measures 1-1/4″ in width, its perforated square tubing format makes it a versatile choice for signage frames, traffic safety installations, and lightweight outdoor supports. The galvanized finish offers corrosion resistance, while perforations enable easy mounting and attachment of additional components. Suitable for signs, guards, and flexible outdoor installations where perforation is advantageous for mounting hardware.
Buying Guide: Key Purchase Considerations
- Material selection: Steel provides high strength and cost efficiency, while aluminum offers lighter weight and corrosion resistance. For outdoor or damp environments, consider galvanized or coated options to reduce corrosion risk.
- Wall thickness and section modulus: A thicker wall increases strength and stiffness but adds weight. Match wall thickness to the expected load and fabrication method (welding, drilling, or cutting).
- Dimensional accuracy: Verify exact outer dimensions and internal bore where applicable. Tolerances influence fitment with other components and accessories.
- Perforation patterns: Perforated tubes enable mounting, cable routing, or weight reduction. Ensure the pattern and hole size align with mounting hardware and anticipated loads.
- Length options: Some products come in fixed lengths; others offer custom cut-length services. Plan for extra length to accommodate joints, overlaps, and future adjustments.
- Machinability: Aluminum is easier to machine and weld than most steels; consider oxidation and coating requirements when selecting materials for fabrication.
- Environmental and use-case fit: Indoor framing contrasts with outdoor signs or corrosion-prone settings. Choose products with appropriate finishes and coatings.
- Cost vs. performance: While steel typically offers better strength per dollar, aluminum may reduce weight and handling costs in large-scale projects.
In summary, the best 2×2 square tubing choice depends on the balance of strength, weight, and environmental durability you require. For heavy framing with occasional welding, hot-rolled steel options are reliable. If weight reduction and corrosion resistance are priorities, aluminum 6063-T52 stands out. For perforated needs, consider models that balance hole pattern with structural integrity, ensuring compatibility with your fasteners and supports.
