Description

Ashzip is a standing seam roofing system, which is designed for use on roof pitches down to 1.5 degrees. Ashzip panels are roll formed from continuous strip coil to any required length, and are mechanically seamed together onto secret-fixed halter clips and then locked into position using a zipping machine. Fasteners are positioned below the roof covering at the base of the halter and are therefore concealed from view. The result is an integral roof covering that has no joints or end laps, making rainwater penetration virtually impossible.

The Ashzip profile is available in cover widths of 300 and 400 mm and can be produced in a tapered format to create a radial roof on plan. Movement of the top sheet due to thermal expansion is catered for by a sliding action over the head of the halter. Any joints or apertures in the roof should therefore be designed to ensure that the movement of the sheets is not impaired in any way.

The Ashzip external profile is available in either 3000 series aluminium or GZ275 pre-painted galvanised steel. In addition copper and stainless steel profiles are also available.
