6063 Aluminum Rectangular Tubing 3/4 in x 1-1/2 in 0.125 in Wall

Our review of this 6063 aluminum rectangular tubing focuses on who will get the most value from a pre-primed, structural-length section. For fabricators, hobbyists, and light industrial users who need a ready-to-finish aluminum profile, the tubing delivers a straight, consistent cross section and an exterior that is primed for painting or assembly. The single biggest reason to buy is the convenience of an exterior finish primed product that reduces upfront surface prep compared with raw mill stock, while still offering the typical corrosion resistance and machinability of 6063 alloy.

Key Features

• Material and temper: 6063 aluminum in T52 temper provides a good balance of strength and formability for light structural and cosmetic applications.
• Pre-primed exterior: The tubing arrives with an exterior primer which saves time on initial finishing and improves paint adhesion for final coating.
• Fog light holes primed: Primed with fog light holes CAPA so drilled or prepunched areas are protected and ready for installation where applicable.
• Standard size and length: The 3/4 in x 1-1/2 in profile with 0.125 in wall thickness and 48 in length is convenient for framing, trim, and small structural runs without extra cutting.
• ASTM B221 specification: Manufactured to an industry standard that ensures consistent dimensions and alloy properties for predictable use in projects.

Who It's For

This tubing is ideal for metalworkers, fabricators, and DIYers who need a uniform rectangular profile ready for finishing; the pre-primed surface reduces preparation time for painting or assembly. It also suits light-duty structural uses like display frames, trim pieces, or prototype enclosures where a neat, painted exterior is desired.

It is less appropriate for applications that demand mirror-smooth shop-finish edges or pin-perfect cosmetic surfaces without additional finishing, and buyers who need corrosion-sensitive outdoor parts may prefer specially coated or alloy-specific alternatives.

Pros & Cons

Pros

• Pre-primed exterior saves time and improves paint adhesion for finishing steps.
• Consistent 48 in length and standard profile make layout and joining straightforward for small projects.
• 6063 T52 temper offers good formability while maintaining usable strength for light structural work.
• Manufactured to ASTM B221 for predictable dimensions and alloy properties.

Cons

• Some customers report rough edges and surface scratches from shipping, so additional deburring and touch-up may be required.
• Not intended as a final cosmetic surface in projects that require flawless, scratch-free finishes without additional preparation.

Our Verdict

For users who value a ready-to-finish aluminum profile, this 6063 rectangular tubing is a practical and cost-effective choice, offering a primed exterior and reliable dimensions under ASTM B221. It is best for light structural uses and finishing projects where minor edge work and touch-up painting are acceptable; buyers needing pristine, scratch-free cosmetic parts should plan on additional surface prep or choose a different finish.

Frequently Asked Questions

Is the tubing ready to paint out of the box?
The exterior arrives primed which improves paint adhesion, but light cleaning or scuffing may be needed for optimal finish.

Are the dimensions consistent for fabrication?
Yes, the tubing is produced to ASTM B221 standards for consistent profile and wall thickness suitable for layout and joining.

Will the edges be smooth enough for visible trim?
Some customers report rough edges from shipping, so expect to deburr and dress edges before using in visible trim applications.
