Decking Systems

There are 6 standard RAL colours:

RAL 7016 – Anthracite Grey
RAL 7037 – Dusty Grey
RAL 7039 – Quartz Grey
RAL 7040 – Window Grey
RAL 8014 – Sepia Brown
RAL8019 – Grey Brown

Any other RAL colour would be POA

This is dependent on which board is required. Please refer to individual product pages for further details.

Yes, we can provide deck boards cut to length and packaged by balcony or by area. If required, please discuss your requirements with us.

It is possible to dampen the noise which aluminium makes when you walk on it by using our 1 mm shock-absorbing self adhesive gasket in between the joist and the decking. Please note that the shock-absorbing 1 mm self-adhesive gasket is not non-combustible but is exempt from this requirement under the building regulations, Regulation 7, paragraph 3.

The temperature of aluminium decking depends on the climate, sunlight, board profile and colour. Aluminium heats more quickly than materials such as oak but, because it conducts heat efficiently, heat spreads across the board and dissipates more quickly. Oak heats more slowly but retains concentrated heat for longer due to its lower thermal conductivity. See the comparison table on this page for more information.

If a deckboard has to be ripped down its length, then the cut board can be supported using our E-termination profile or our EBS End Board Support profile. Where required, the Cantilever Deck Board Support can also be used to provide additional support to the deck board on steel frame applications.

No, the powder coating on our DFB provides sufficient protection against bimetallic (galvanic) corrosion. The corrosion occurs when two dissimilar metals come into direct contact with one another. So, if mill-finish aluminium, such as a cleat or joist, were being fixed to balcony steels, a non-combustible isolation layer would be required.

This can be done by using joists and cleats or pedestals.

No.

The maximum cantilever depends on joist centres (board span) and the profile selected. Figures are calculated to EN 1990/EN 1991 Eurocodes, based on a 2kN point load at the end of the cantilever, with deflection limited to Span/200. A dash (–) means that joist centre exceeds the supported span for that profile.

Always check the specific board profile and joist centre combination against these tables before installation.

The maximum spacing between decking joists depends on the decking material, anticipated load, manufacturer’s guidance and local building regulations. Timber and composite decking typically require joists at 40.6 cm centres, although closer spacing may be needed for heavier loads. With RYNO aluminium decking joists for waterproofed balconies, terraces and roofs, the maximum permitted spacing is 80 cm centres. Always refer to the specific system requirements before installation.

TerraSmart decking systems are designed to be loose laid onto the roof/balcony where possible. Fixing down of the system may be required if there is a risk of wind uplift. This should be determined by a wind uplift survey carried out by an engineer. There are various methods of either fixing the decking down, or increasing the dead weight of the system to prevent uplift if required and each project should be assessed on its own merit.

The Base Rubber Shock Pad (BRSP) is not a mandatory item. We recommend installing it when installing the decking system on waterproofed substrates as the pad will help protect the waterproofing from any damage. It can also act as an acoustic dampener. It is not non-combustible as it is made from recycled rubber however as part of our fire testing process, the BRSP was included within the roof system tested to EN 13501-5:2016 which achieved B_ROOF(t4).
