The BA-Versaspan 150 (SS150) standing seam panel is formed with an on-site/in-shop continuous metal roofing panel roll forming machine (New Tech SS Multipro). This machine produces a standing seam panel with a seam height of 38.1 mm (1.5") and profiles can vary from 25.1mm (12") wide up to 508 mm (20") wide. This machine also produces FF 100 (BA-Versasnap), SS 675 (BA-Versaclip), SS 100 (BA-Versaspan 100).

On-site roll forming provides for the elimination of end laps with continuous panel forming capabilities in lengths up to 200' plus (depending on coil size and handling/maneuvering.
