Curveline's "crimp-curving" process can be performed on a wide range of metal panels — including exposed fastener roofing and wall panels, standing seam roofing profiles, decking profiles and more.

The curving process makes it possible to use many profiles interchangeably — e.g., a roofing profile may be used in a siding application, and vice versa. In addition, many profiles are curvable in either direction. 

To use the Curveline process, simply select the panel manufacturer and profile of choice, determine the required substrate and gauge, and specify the desired radii and angles of curvature. The curving parameters provided here are intended to aid in the design process.

Listed below are general curving parameters for each profile. Information on specific panel products is available from the Manufacturers.
