Our AP-1125 Aluminum Wall Panel System is our most economical aluminum plate wall panel system. All of the panel corners for the Aluminum Plate Wall Panel System are welded and ground smooth with an option for tight fitting non-welded corners. Our Aluminum Plate Wall Panels are reinforced with stiffeners as required by design loads to meet deflection criteria as well as eliminating the possibility of “oil canning”.

Utilizing Protean’s standard installation details with formed attachment legs, the AP-1125 Series metal wall panels are sequentially installed to the structure with mechanical fasteners as a fully-caulked system.

The AP-1125 Series Factory Formed Metal Wall Panels can be designed to be non-sequentially installed utilizing clips attached to the metal wall panels, allowing panels to be installed or removed individually.

Aluminum offers superior weatherability can be custom painted to match or contrast other material on the project if required. The panel joints are ½” minimum joint sealed with backer rod and sealant compatible to the panel finish to provide a weather tight system.

See our aluminum Column Cover page for more information on our Column Covers and Beam Wraps to match or accent your metal panel system.
