Effective of 700mm for each sheet

Topdek 700 is a concealed clip roof deck suitable for a variety of domestic industrial and commercial uses. Specially designed clips eliminate the need to pierce the roof sheet to fix the roofing purlins. Due to the combination of rib height and concealed clips Topdek 700 can be installed on roofs with pitches as low as one degree. This reduces the need for extensive parapet structures to conceal the roof reducing flashing costs and providing a safer area for maintenance.
