Petersen’s PAC-CLAD Precision Series wall panels now includes the Box Rib line. The four new Box Rib wall panels feature 87-degree rib angles and a variety of rib spacing patterns. The Box Rib architectural wall panels are 1-3/8” deep with a nominal 12” width. Architects and designers can specify one of the four panel profiles or combine multiple Box Rib panels on the same surface to create custom patterns of ribs and valleys. Petersen’s Box Rib panels are ideal for practically any structure that requires exterior wall cladding such as schools, hospitals, banks, sports facilities, office and industrial buildings and most other nonresidential applications, but also residential buildings. Each of the four Box Rib profiles is offered in a no-clip fastener-flange option or a clip-fastened panel to accommodate thermal expansion and contraction. They deliver design flexibility while combining bold visual effects with easy, cost-effective installation.
