Eurotray^® Angle Seam

Eurotray® Angle Seam Performance

Looking to add interest to your design or project? Consider the bolder look that Eurotray® Angle Seam offers. This member of the Eurotray® family lends itself well not only as a striking roofing profile - but as an exceptional wall cladding solution as well. In cladding situations, Angle Seam can be run both vertically or horizontally. Angle Seam can also be concave curved.

^{Cover width may vary based on manufacture location. Please consult you local Dimond branch for local cover dimensions}

Short sheet and flashing considerations

Unless specified otherwise short sheets and flashings will usually be made on an automatic bending Raz machine.

Ensure to state on the order "manual folding required to 10mm minimum bend" when ordering short sheets or flashings because some manufacturing locations have Raz machines with 11-12mm minimum bends.

Sheet Tolerances
Sheet width: ±5mm
Sheet width for aluminium +0, -15mm. If sheet cover widths are critical, advise Dimond Roofing at time of order.
Sheet length: +10, - 0mm. For horizontal wall cladding where notified at time of order of intended use, tighter tolerances can be achieved +3, -0.

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

Oil Canning

Oil Canning is the visible waviness in the flat areas of metal roofing and walling. Oil canning produces an aesthetic effect inherent in standing seam tray profiles and profiles/flashings with wide flat elements. It does not cause detriment to product performance.

Oil canning can occur during the forming and installation processes and during thermal expansion of the roof sheeting during its life cycle. The effect can be more or less pronounced depending on differing light and sun angle conditions and the coating gloss levels.

For fully supported standing seam tray profiles, oil canning can be reduced by the vented roof underlay (e.g. Tyvek Metal), in addition, backer rods under the tray can also be used.

There are several options to reduce the oil canning effect in tray-type profiles and flashings, for example,

a) increasing the thickness of the material,

b) using stiffening swages in wide flat elements and

c) limiting flat elements to less than 150mm width.

For further information, please refer to the New Zealand Metal Roof and Wall Cladding Code of Practice, Section 12.3.

Fastener Design

Eurotray® Angle 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 when using Zinc avoid contact with Bituminous paper underlays and use Covertek 403.

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. 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.

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.

Product Technical Statement

To help you get through the building consent process as quickly as possible, we have developed the Product Technical Statement (PTS) downloads to make it quick and easy for both Architects and Home Owners to access the documentation required.

The PTS downloads hold all of the information that the council requires for a building consent where Dimond product is specified.
