PAC T-250 panels are factory-formed or field-formed to length and field-seamed. The panels have been designed for application over a wide variety of substrates on roof slopes as low as 1/2 : 12. PAC T-250 panels can be produced in 22 and 24 gauge steel or .032 and .040 aluminum. The PAC T-250 panel combines structural performance with architectural aesthetics. PAC T-250 panels feature a 2.625" nominal finished panel height from the deck that requires mechanical field seaming after installation. The panels have a continuous and/or intermittent concealed-fastener clip system designed to allow for thermal expansion/contraction. Sealant beads are factory-applied to the seam cover.
