Lightweight. Strong. Versatile.

Strength Through Form.

ASCO’s expanded aluminum sheet delivers rigidity, ventilation, and strength — all from a single solid sheet of metal.

Expanded mesh is created by slitting and stretching aluminum into a diamond or flattened pattern, eliminating waste and maximizing efficiency.

The result: a lightweight, corrosion-resistant material that performs across architectural, industrial, and protective applications.

From machine guards to sunshades, expanded metal is the unsung workhorse of the fabrication world — built to last, built to move air, built by ASCO.

Why Expanded Aluminum

Form Meets Function.

Expanded aluminum combines strength and openness, offering a practical solution where visibility, airflow, or drainage are required — without the weight of perforated or welded mesh.

Advantages

Types of Expanded Aluminum

Type Description Common Uses
Standard (Raised) Diamond-pattern mesh with a textured, slip-resistant surface. Stronger and more rigid due to raised strands Machine guards, catwalks, ventilation panels, stair treads
Flattened (Smooth) Cold-rolled after expansion for a smooth, even surface. Easier to fabricate and paint Decorative panels, sunshades, enclosures, architectural screens

Material Grades: 3003-H14 and 5052-H32

Finish: Mill finish standard; anodized or painted by request.

Alternate Expanded Metals

ASCO also supplies expanded steel and stainless expanded mesh for heavier industrial applications where aluminum’s light weight isn’t enough. These are available to order in both raised and flattened patterns, with galvanized or powder-coated finishes.

Standard Sheet Sizes

Custom dimensions and cut-to-fit sheets available upon request.

Common Applications

Why ASCO

Our expanded metal is sourced through top U.S. mills for consistent pattern accuracy, sheet flatness, and alloy integrity.

We offer in-house shearing, brake forming, welding, and custom framing services for ready-to-install components.

No matter the mesh type or material, ASCO ensures you get fit-ready product, fast.
