AP-1125 Wet Joint Metal Plate Panels

Aluminum Plate Panels (AP)

The AP-1125 Series is formed plate barrier system, which provides a smooth joint with welded and ground corners. AP panel systems are best used in low rise applications that go down to grade, as accents with low volume custom colors. The AP-1125 system is the best fit for projects with multiple bends, shapes and conditions where long service life is desired.

Utilizing standard installation details, AP-1125 series panels are sequentially installed to the structure with mechanical fasteners and formed attachment legs. The minimum joint of ½” is sealed with backer rod and sealant compatible with the finish. We recommend use of hat girts and self-tapping screws; however, our panels can be fastened to flat strap furring or direct to 5/8” or heavier plywood. Optional design with attachment clips allows non-sequential installation so panels can be installed or removed individually.

Optional free-floating design for seismic consideration (AP-2125) is sequentially installed with stainless steel alignment pins through slotted side joint on an extended attachment leg.
