Petersen expands its family of PAC-CLAD Precision Series wall panels with the introduction of 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 in. deep with a nominal 12-in. width. They deliver design flexibility while combining bold visual effects with easy, cost-effective installation. 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.
 
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.
 
“Petersen continues to respond to architects who tell us they want more options for wall cladding by introducing the Box Rib line,” says Mike Petersen, president of Petersen. “As architects’ creativity evolves, our product line also evolves with the same high-quality manufacturing, technical support and testing that Petersen is known for.”
 
The Box Rib panels are part of Petersen’s PAC-CLAD Precision Series line of wall panels, which means they can be mixed with the seven Precision Series Highline wall cladding products to create a wide variety of custom patterns for a building’s exterior. The Box Rib panels are backed by the following tests: ASTM E-330, ASTM E-1592, ASTM E-283 and 331, AAMA 501.
 
Minimum Box Rib panel length is 4 feet; maximum lengths are 30 feet for steel, and 22 feet for aluminum on the no-clip fastener-flange version, with longer lengths available on clip panels. The Box Rib panels are available in 24 and 22-gauge steel, .032 and .040 aluminum in 46 standard PAC-CLAD colors, plus Galvalume Plus. BIM, CAD and related files are being posted on pac-clad.com as they become available.
 
Box Rib panels, as well as all Precision Series wall panels, can be installed horizontally or vertically. Additionally, Precision Series Box Rib, Highline and HWP panels can be specified as perforated, but only in aluminum for use in applications such as equipment screens, over graphics or for architectural flair.
