Eurotray® Double Standing Seam Performance




Following a traditional European design and exhibiting a modern day seamless appearance, Double Standing Seam is typically specified and formed using higher end materials like copper, zinc and aluminum. Double Standing can be found in a number of architecturally noteworthy designs. Double Standing Seam can also be concave curved giving extra flexibility to the design of your building.

Roll-forming facilities at: Auckland, Christchurch and Invercargill

Curving facilities:
Machine is transportable
For curving restraints check with the local RoofingSmiths.

Sheet lengths:
Eurotray® is custom run to order. Where long sheets are used, consideration must be given to:

  • Special transportation licences
  • Should be run on-site
  • Site access for special lifting equipment
  • Fixing techniques to accommodate thermal expansion

**NOTE

Photovoltaic laminates (PVL’s) can be installed on to this profile at an additional cost when the cladding is completed and other trade have finished or it can be installed at a later date.
Laminates are 348mm wide and available in 5.910mm and 2.585mm lengths. Lead time of 16 weeks.
Laminates cannot be installed on raking sections of roofs

Fastener Design



Eurotray® Double Standing Seam 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 407. Avoid Bituminous underlays in contact with Zinc. 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.

Clip Fixing Requirement - 2 fixings per clip per purlin

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.

Minimum pitch for Euro-Tray® Double Standing Seam is 3 degrees.

Flashing and jointing details when using Copper or Zinc materials are required to be solder, silicone sealants are not to be used on these materials.
