High-Quality Metal Extrusions & Shapes for Every Application

From standard profiles to engineered solutions, ASCO connects you with the extrusions and shapes your projects demand—efficiently, reliably, and built to spec.

At Aluminum Supply Company (ASCO), we provide a comprehensive range of aluminum extrusions and metal shapes designed to meet the needs of architects, engineers, and manufacturers across industries.

We aren’t a mill—we’re your bridge to one. Leveraging deep partnerships with trusted U.S. extrusion producers, we maintain a steady supply of standard profiles and can source or manage custom dies for high-volume runs.

Whether you need architectural aluminum, structural shapes, or stainless and carbon steel profiles, ASCO delivers Detroit-level reliability backed by decades of technical expertise and a reputation for service that still carries the Marshall family name.

From blueprint to buildout, we supply the metal that holds your vision together.

Hundreds of metal extrusions line shelves in the Aluminum Supply Company warehouse.

Architectural & Structural Aluminum Extrusions

6063-T5 Architectural Extrusions

Known as the architect’s alloy, 6063-T5 aluminum is prized for its smooth finish, fine detail, and superior corrosion resistance. It’s ideal for visible architectural components such as window framing, glazing systems, trim, and decorative assemblies.

Traits

Common Uses

6061-T6 Structural Extrusions

When the design calls for strength and stability, 6061-T6 delivers. With nearly double the tensile strength of 6063, it’s the preferred alloy for load-bearing, high-stress, or high-performance structures.

Traits

Common Uses

Several round rod extrusions are stacked on a shelf.
Several round tube extrusions rest on a shelf.

Steel & Stainless Shapes

Steel Shapes: Hot-rolled (HRS) and cold-rolled (CRS) profiles provide dependable performance in load-bearing and industrial applications.

Stainless Shapes: 304 and 316 stainless deliver unmatched corrosion resistance and polished aesthetics for environments where hygiene and longevity matter.

Applications

6063-T5 vs. 6061-T6

What's Right for You?

Both are exceptional alloys—but each serves a different purpose.

As a Rule

If appearance and finish are critical, choose 6063.

If load and performance matter most, choose 6061.

Need both? Many ASCO clients do—our inventory and fabrication processes are set up for mixed-alloy builds and multi-material assemblies.
