Dimondek 300

Dimondek 300 is a smaller scale, concealed fixed companion to Dimondek 400 and is especially suitable for commercial applications where fine detail and design proportions are an integral component of the architectural brief.  Dimondek 300 can be used at a low pitch like all Dimondek profiles and the stiffened ribs provide structural strength and weather tightness as well as the ability to be secured in place without the need for fixings to penetrate the sheet.
