Petersen Aluminum offers several wall and soffit profiles for perforation in a nearly endless combination of hole sizes and patterns to complement virtually any architectural design or need. Perforated metal can provide a contrasting look with any non-perforated metal to create visual interest on any project. Perforated panels can be specified to diffuse light, air or sound, or simply for architectural flair. Typical applications include equipment screens, partitions, sign panels, parking decks, guards, interior acoustical applications and enclosures of any kind. Aluminum can be perforated for any project, but perforated steel is limited to interior applications only. An extra charge is applied for perforation. Check with local facility for specific panel profiles that can be perforated. A 20-year finish warranty is offered on perforated material.
