A New Zealand inspired design and the most popular profile of the Eurotray® family, Eurotray® Roll Cap offers clean lines and a uniquely robust and distinctive look. Visualise the traditional timber board and batten look and then imaging this in metal, and you have Roll Cap. The profile is ideally suited to withstand New Zealand harshest climates.
Minimum pitch 3°- In snow loading zones N1-N5 (as per Section 15 of NZS 3604), please contact the Dimond technical team at rooftech@dimond.co.nz for the minimum pitch requirements.

Eurotray® Roll Cap Fastener Design
Eurotray® Roll Cap roof cladding must always be installed over a plywood (12mm minimum) substrate with a moisture content of less than 18% and made wind tight, with purlin supports underneath at 600mm centres in low to high wind zones and 400mm centres for very high and extra high wind zones. 8g x 40mm countersunk stainless steel screws at 150mm centres around the panel edged and 200mm centres on the intermediate supports. The fasteners should be no closer than 10mm to the edge.
A 3mm expansion gap should be provided between the sheets. All joints should be staggered and taped over before placing underlay, Dimond Roofing recommend the use of vented type underlay such as Tyvek metal or Covertek 403 with drainage mat. This allows added air-flow between the underside of the tray and substrate, it also helps to reduce oil-canning in the tray.
Fasteners that are used to secure Eurotray® down as a roof cladding must penetrate through the substrate and into the purlin a minimum of 30mm for timber and 6mm for steel purlins. For wall cladding the fasteners must be long enough to pass through the substrate, cavity batten and into the main frame by 30mm for timber and 6mm for steel.
(1) Standard 12mm Substrate
(2) over vented cavity batten, 18 - 25mm thick
Design
Fasteners must be fixed closer together on the periphery edges of all roofs in areas of High to Extra High Wind Zones.
Unlike profiled metal cladding, the point load imposed on a fully supported cladding is supported by the substrate underneath.
