Metal Buildings 101: Covering and Trim Details
Both panel types are available in 24 gauge or 26 gauge steel with a painted or Galvalume finish. Galvalume is a zinc and aluminum coating over the steel that offers extremely long life and weathers to a light finish.
PBR Roof and Wall Panels
Arco uses a 26 gauge PBR panel for our standard roof and wall covering. An industry favorite, the PBR panel's deep ribs create an even-shadowed appearance. The panel laps are easier to align and stitch together properly, so the panels install more quickly, and the area between the major ribs is reinforced with minor ribs. On roofs, the bearing leg protects against foot-traffic damage and helps prevent the panel from "rolling" and perhaps creating leaks. The PBR panel is one of the most economical and durable covering systems available.
