Perforated Aluminum Roll Forming Material Guide: Coil Sizes, Patterns & Uses

Perforated Aluminum Roll Forming Material

1. Overview of Perforated Aluminum in Roll Forming

Perforated aluminum is aluminum sheet or coil that has been punched with a pattern of holes to create a lightweight, functional, and decorative material.

In roll forming, perforated aluminum is widely used for architectural façades, ceiling panels, HVAC systems, acoustic panels, and decorative cladding.

Compared to perforated steel, aluminum offers lower weight, excellent corrosion resistance, and easier formability, making it ideal for modern construction and design applications.

2. Material Composition & Structure

Perforated aluminum typically consists of:

Aluminum base alloy
Perforation pattern (punched holes)
Optional coating or finish

Common Alloys
