How do I buy decking boards?

We supply ready made off-the-shelf premium deck boards made from Yellow Balau which is a very hard wearing dense hardwood. Balau does not need to be treated and will last for many years with little to no maintenance.

Balau is a Malaysian hardwood with natural durability and will gradually weather to a silver-grey colour.

These boards are sold with 2 different grooved styles. There is a reeded option with thin shallow grooves and a castle option with deep grooves. The grooves are often thought to act as a grip underfoot but they are mainly to provide a stress release to stop the boards curling when they are thin.

The dimensions can range from:

  • 19mm x 90mm Reeded
  • 21mm x 145mm Smooth both face
  • 21mm x 145mm Reeded/ Reversible
  • 21mm x 145mm Smooth/ Castle
  • 28mm x 145mm Reeded/ Reversible

How can I buy timber for bespoke decking?

The best way to buy decking as a bespoke design and style is to buy your own timber. Buying timber for decking is really not that complex and mainly comprises of planks over a sub frame. The thickness of the planks is the main key factor.

If you are building a sub frame you must make sure the joists below the deck are spaced adequately to provide a strong sub structure. Then you can establish the thickness of planks/boards.

Using a hardwood for decking will allow a thinner board than softwood as they are more dense and will not flex. Please consult your joiner/builder for their advice on thickness of decking boards before buying. They will know what thickness to order based on the sub frame they intend to build.

Please also get in touch if you wish to discuss your decking project or if you wish for us to consult with your builder/joiner.

Choose from our range of exterior hardwoods and softwoods to build your bespoke decking.
