Curveline’s crimp-curving methodology greatly increases the strength and rigidity of profiled metal panels, making it possible to create S-shaped panels up to 26 ft. long when 20 or 22 GA nestable decking is used, or up to 20 ft. if 18 GA decking is used.

The only other options for S-shaped decking are stretch-forming, which is generally cost-prohibitive; or the application of several shorter panels to create the “S”, which involves added structural support.

The Curveline method requires minimal substructure and produces optimum aesthetics, making it suitable even for applications where decking remains exposed on the underside.

Panels suitable for S-curved applications include standard or acoustical nestable “B” deck panels in 22 to 18 GA steel. A selection of exposed fastener roofing and siding panels can also be curved in the same manner. Minimum radius varies depending on the panel gauge and number of curves desired: Consult Curveline regarding your specific application.
