Jarrah Hardwood Decking

A very durable and hard wearing species, Jarrah is a popular choice for exterior decking.

Jarrah ranges in colour from light to dark reddish brown and has a durable course texture.

We strongly recommend coating Jarrah as it reduces shrinkage & swelling.

We stock 90x21 and 135x21, curved and pre-oiled profiles.

Although not very common in New Zealand, coating your deck will extend its life. We recommend a minimum of one coat of a suitable exterior timber decking coating or oil be applied to all four sides plus cut ends of the decking prior to installation. Some species can be factory coated prior to delivery.



Annually cleaning your deck will help prolong its life, a light detergent that contains an anti-fungal agent is best. Avoid using high pressure waterblasters or harsh chemicals.


Any coating or oil applied may require subsequent recoating. Refer to coating manufactures maintenance schedule.


Removing any items that will trap water underneath them (furniture, pot plants, etc.) for the duration of winter will extend the life of your deck and help keep it looking great.
