Alternatives (similar colour) & Work-ability

Jarrah is readily available and usually in good stocks, however if you wanted a reliable alternative timber we suggest using Merbau or Spotted Gum, mainly due to their similarities in grain and durability.

Jarrah colour is not as dark as royal red, however with a pigmented stain this colour can still be achieved.

Jarrah is relatively easy to work with. It is a very durable and hard timber that will require tools with sharp blades to ensure a smooth finish.

It is recommended to pre-drill and countersink the holes when using decking screws as the timber is very dense and prone to splitting especially at end boards.
