PAC-CLAD Architectural Sheet and Coil

PAC-CLAD is a versatile prefinished sheet metal coating of 70% polyvinylidene fluoride (Kynar) that is applied to Galvalume steel or prime quality aluminum. Originally developed for use in abrasive environments, PAC-CLAD has proven to be ideally suited for applications in roofing, wall, curtainwall, storefront and trim applications. PAC-CLAD is now available in 45 colors carefully selected to complement a range of building materials.


Petersen is an industry leader in providing factory-produced metal panels, maintaining extensive roll-forming equipment in all regional plants. Each Petersen facility produces panels that have been leveled. Standing seam, exposed fastener, flush wall, soffit and horizontal wall panels are factory-formed in lengths up to 64’. Refer to the specific product pages, or consult the local factory for maximum lengths and capabilities for each facility. Matching flashing and trim also may be factory-formed, or field-formed from PAC-CLAD material.

Petersen fabricates a wide range of roofing accessories from stocked PAC-CLAD colors and gauges. Trim, gutters and downspouts can be produced from Petersen’s 45 standard PAC-CLAD colors.

Perimeter/Roof Edge Systems
