The PAC-150 90° Seam[1] is a single-lock, mechanically seamed standing-seam panel from PAC-CLAD[2]. Concealed clips secure the panel, which are seamed in the field. PAC-150 is also available in a double-lock 180° configuration; seam selection depends on project uplift requirements.

PAC-CLAD levels the coil used for field-forming to improve panel flatness, says PAC-CLAD, with a minimum panel length of approximately 4 feet.

The 1.5-inch panel is available in 12–20-inch widths, in 24-gauge steel or .032-inch aluminum. It can be installed on slopes as low as 1:12 and curved to a minimum radius of 20 feet.

PAC-150 is produced in Georgia, Maryland and Arizona.
