Zadery 1.5 x 1.5 Aluminum Square Tube
Product overview: Seamless 1.5″ x 1.5″ aluminum tube with 0.125″ wall. Natural mill finish and clean-cut ends suit 80/20 DIY framing and general structural use. Best for lightweight frames, shop fixtures, and architectural trim. The seamless design helps reduce stress concentrations in lightweight structures. Best for: hobbyists and light-duty projects where corrosion resistance and easy machining are valued. Caution: aluminum’s lower rigidity compared to steel means for high-load frames, verify load requirements before use.
Generic 1.5×1.5 Mild Steel Square Tube
Product overview: 1.5″ x 1.5″ square tube, 1/8″ wall, hot-rolled steel. Suited for rigid structural frames and industrial fixtures. Best for: projects needing higher strength and durability in load-bearing frames. Caution: steel is heavier and more prone to corrosion unless treated or painted; pick this when strength is the priority over weight.
MECCANIXITY Aluminum Square Tubing, 1.5″x1.5″x16″
Product overview: Two pieces of 1.5″ x 1.5″ aluminum square tubing, 0.08″ wall. Made from 6063 aluminum, known for corrosion resistance and good strength-to-weight ratio. Best for: decorative frames, light machinery supports, and projects requiring portable, easy-to-handle aluminum profiles. Caution: shorter lengths limit large-frame builds without splicing or combining sections.
Baudelun 1.5”x1.5” Aluminum Square Tubing
Product overview: 1.5″ x 1.5″ aluminum square tube with 0.125″ wall, 6063-T6 alloy. Suitable for industrial machinery framing, architectural accents, and furniture frames. Best for: projects requiring smooth edges and a clean appearance with good corrosion resistance. Caution: ensure compatibility with any mechanical fasteners or joints used in your build.
OnlineMetals Steel Square Tubing, 1.5 x 1.5 x 0.12
Product overview: Hot-rolled carbon steel square tubing, 1.5″ x 1.5″ with 0.12″ wall. 36″ length. Best for: structural frames, racks, and fixtures requiring rigidity and durability in shop or job-site settings. Caution: heavier than aluminum; consider handling and mounting methods to manage weight.
Buying Guide
What material should I choose for my project?
Aluminum (1.5″ x 1.5″) offers light weight, corrosion resistance, and easier machining, making it ideal for decorative frames, light-duty machinery, and portable structures. Steel provides higher strength and rigidity for heavier loads, but adds weight and may require coatings to prevent corrosion.
What wall thickness is best?
A thicker wall (0.125″) increases stiffness and load-bearing capacity, beneficial for structural frames and supports. A thinner wall (0.08″ to 0.125″ depending on grade) reduces weight and is easier to cut, ideal for non-load-bearing or lightweight assemblies.
What length should I order?
Longer tubes minimize joins but complicate transport and handling. Shorter pieces are easier to assemble and may be welded or joined with brackets, but require more joints to achieve the same overall length.
Which finish matters?
Natural mill finishes look clean and require minimal processing, while anodized or powder-coated finishes increase corrosion resistance and aesthetics for visible installations.
What about compatibility and assembly?
Check joint compatibility with connectors, brackets, and fasteners. Aluminum frames often use stainless or aluminum fittings to avoid galvanic corrosion, while steel frames may require coated hardware for longevity.
Practical tips for buying
- Match tube material to load and environment: aluminum for light duty and corrosion resistance; steel for higher strength.
- Verify wall thickness aligns with your structural requirements and cutting capabilities.
- Consider available lengths and whether you will need to join tubes or use mechanical fasteners.

Frequently asked questions
- What is the difference between 6063-T6 aluminum and 6063-T5? 6063-T6 generally offers greater strength and corrosion resistance, while T5 denotes a specific aging process that can impact malleability.
- Can I weld aluminum to steel tubing? Welding dissimilar metals requires special techniques and precautions to prevent galvanic corrosion; consider using mechanical joints instead.
- Is 0.125″ wall thickness suitable for outdoor use? It depends on load and exposure. Aluminum with proper finishes is suitable for many outdoor applications, but steel may require coatings.
- Which tube is best for DIY furniture frames? Aluminum tubes are often preferred for lightweight frames, while steel can handle heavier loads.
- How should I cut square tubing cleanly? Use a proper square-cut saw or a metal-cutting blade, and deburr edges for safe handling.
