Timber Decking Overview

About Timber Decking

Timber’s natural high resistance to weather, rot, termites, and even marine borers, makes this the ideal timber for decking.

Timber is a popular timber in Australia and has been used as an exterior timber in construction since the 1840’s because of its durability and strength. Timber trees can be found in forests from Perth to Albany in the southwest of Western Australia where the soil is rich in iron and aluminium.

From boardwalks in extreme environments to veranda and alfresco decking, Timber’s striking appearance and long-term durability makes it Australia’s premium choice.

Why use Timber Timber Decking

Timber is an excellent choice for outdoor applications as it is naturally resistant to weather, rot and termites. It is also resistant to marine borers, making it a good choice for harsh marine applications such as wharf and bridge construction.

Timber’s natural colour ranges from a deep brown-red to blonde. Paired with its durable qualities, this makes it a desirable species for architectural design and decorative elements. It is often used for floorings, linings, furniture, joinery and parquetry.

Timber is one of the Australian hardwood species that has natural fire resistant properties (BAL 12.5 & 19), making it an ideal choice for outdoor decking applications where durability and safety are paramount.

Thanks to its durability and strength, Timber is a highly versatile timber which is used for both structural and design applications. As it is both a highly practical and aesthetic timber, Timber is an ideal choice for public spaces, commercial buildings and high end residential properties.

Mortlock Timber’s Timber decking and cladding products are manufactured in Western Australia. As a locally sourced and manufactured timber, Timber is a sustainable option.

Thanks Mortlock as self designers and builders we loved the look of Shou sugi ban in the images we had seen on line and included it as the major feature on the front of our new home. We used the tongue and groove cladding burnt to the highest level, it well and truely lived up to our expectations in both look and workability and it’s been loved by everyone who has seen it. We would highly recommend Mortlock for charred timber cladding. - Gary Crameri
Mortlocks pre oiled timber product is a quality product that makes a quality finish easy to achieve - Andrew Byers
We used the spotted gum 40 x 40mm battens on this project. I was really surprised with how quick and simple the installation was. It easily removes labour time to install, also a very sleek finish. Can’t wait to use the product again. - Patrick Clark
