Metric sizes such as 20x20 mm, 25x25 mm, 40x40 mm, 50x50 mm, 60x60 mm and 100x100 mm are also commonly requested for fabrication and structural projects.

Do you provide an aluminum square tube sizes chart?

Yes. Chalco provides an aluminum square tube sizes chart with metric sizes, inch sizes, wall thickness references and quotation options. Buyers can compare outside size, wall thickness, alloy, finish and cut length before selecting suitable aluminum square tubing for their project.

Can I order 1x1, 2x2 or 4x4 aluminum square tubing?

Yes. Common requested sizes include 1x1 aluminum square tubing, 2x2 aluminum square tubing and 4x4 aluminum square tube. These sizes are widely used for frames, machine supports, guardrails, work platforms, display structures and general fabrication assemblies.

Can aluminum square tubing be supplied in 8 ft or 20 ft lengths?

Aluminum square tubing can be supplied in standard lengths or cut to custom lengths according to project requirements. If you need 8 ft, 10 ft, 20 ft or other cut lengths, please share the required size, wall thickness, alloy, finish and quantity for quotation support.

How strong is 1 inch aluminum square tubing?

The strength of 1 inch aluminum square tubing depends on the alloy, temper, wall thickness, tube length, loading direction and installation design. For structural use, 6061 aluminum square tube is often selected for higher strength, while 6063 is commonly used where surface finish and extrusion quality are more important.

Is aluminum square tubing cheaper than steel?

Aluminum square tubing may have a higher material cost than carbon steel, but it offers lower weight, good corrosion resistance, easier handling and reduced finishing or maintenance needs in many applications. The better choice depends on total project cost, load requirement, environment, installation method and service life.

How much does aluminum square tube cost?

Aluminum square tube price depends on size, wall thickness, alloy grade, temper, surface finish, cutting length, fabrication requirements, order quantity and market aluminum price. For accurate pricing, send your size list or drawing so Chalco can provide a project-based quotation.

What is metal square tubing also called?

Metal square tubing may also be called square tube, square pipe, hollow square profile or square hollow section. In some markets, similar hollow profiles may be called box sections; for that terminology and size comparison, you can also view our aluminium box section product page.

What is the difference between aluminum square tube and square pipe?

In many purchasing situations, aluminum square tube and aluminum square pipe are used to describe similar hollow square profiles. Final selection should be based on outside size, wall thickness, alloy, tolerance, finish and application requirements rather than the name alone.

How do I choose between 6061 and 6063 aluminum square tube?

6061 aluminum square tube is often used for structural frames, machinery supports and load-bearing parts because of its higher strength and good machinability. 6063 aluminum square tubing is commonly selected for architectural profiles, display frames, decorative structures and anodized surface applications.

Should I choose thin wall or thick wall aluminum square tubing?

Thin wall aluminum square tubing is suitable for lightweight frames, display systems and general fabrication parts. Thick wall aluminum square tube is preferred for stronger support structures, machinery frames, platforms and applications where higher stiffness or load capacity is required.
