Eurotray® Roll Seam Performance
With shadowed elegance, this simple but stylish profile can be formed from steel-based materials as well as copper and zinc. Creating a slightly softer finish and a larger shadow effect than Eurotray® Roll Cap, Eurotray® Roll Seam can be machine curved to allow for more expressive detailing.
*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.

Oil Canning
Differential thermal movement between wide, flat surfaces and ribs or corners within a metal sheet can create a visual effect known as oil canning. This refers to the visible waviness or undulations in the flat sections of metal cladding, roofing, or walling. Oil canning is an inherent architectural characteristic of flat metal surfaces and is not indicative of any performance issues with the product.
It may occur during the forming and installation processes, as well as throughout the roof’s lifecycle due to thermal expansion. The visibility of oil canning can vary depending on lighting conditions, sun angles, and the gloss level of the coating.
For more details, please refer to Section 12.4 of the New Zealand Metal Roof and Wall Cladding Code of Practice
Eurotray® Roll Seam Fastener Design
The durability of the fasteners should equal or exceed that of the material being fastened, and the fastener metal or coating must be compatible with the cladding material if in contact. Refer to NZS E2/AS1 table 20 for compatibility requirements.
The minimum embedment of 30mm is the requirement for screws fixing into timber and minimum of three threads to pass through steel. When fastening through cavity battens, thermal break materials etc ensure the length of the screw is increased to accommodate the extra material.
(1) Class 5 fasteners are recommended with steel-based material
Note: Use a minimum 75mm long driver to set the screw
Can be installed as a wall cladding with a substrate over vented cavity battens
N/A – Not available
(1) Class 5 fasteners are recommended with steel-based material

Provision for Expansion
- Non-ferrous tray roofing expands at about twice the rate of ferrous metals, the design of the clip allows the material to move freely therefore sliding clips are not required
