Profiles

Profile familes can broadly be segregated as pierce fastened (corrugate, trapezoidal), and secret fix (tray and trough). Within theses broad categories there are subsets.

Pierce Fastened Profiles

 

 

Symmetrical corrugate or trapezoidal profiles have the advantage of being more easily curved around a radius. Because the ribs are necessarily close together, they have the disadvantage of roof traffic loads having to be spread over two crests, and they have a lower run-off capacity.
