Overview

Why specify perforated metal infill?

Our perforated infill panels are available in a wide variety of patterns. They are constructed of carbon steel that is e-coated and powder coated, or powder coated aluminum. Steel panels are 14 gauge, held within an 11 gauge steel hem, with three holes drilled in the bottom hem to allow water to quickly drain. Available for level or raked (stair) applications.

The no-frame option eliminates the fabricated hem around the outside edge of the panel — our most cost-effective infill panel system. This option is only available in level sections, with a maximum open area of 50%.

Aluminum perforated panels are available in the same hole patterns as steel, but the material is thicker at .125" with 11 gauge hems.
