Dimondek 630 Profile

Dimondek 630 is a revolutionary concealed clip profile, which can be manufactured onsite in lengths up to 100m.  Dimondek 630’s onsite manufacturing allows for gutter to gutter sheets in a continuous draped curve.  The greater span capability means fewer purlins are required and it’s faster to install.  With no screw holes through the roof, leaks are virtually eliminated meaning your roof lasts longer.  With improved lifecycle costs Dimondek 630 is the most economical concealed clip roofing profile on the market.
