Magna Merbau Timber Perth WA

Austim is proud to distribute FSC Certified Magna Merbau Glulam decking, posts and beams.  


Magna Glulam is manufactured under strict Australian Standards and audited for quality assurance by the Glue Laminated Timber Association of Australia.


Magna Glulam is a quality, high strength timber that is perfect for both residential and commercial projects. Its low shrinkage rate (1/5% radial & 2.5% tangential), makes Magna Glulam suitable for all weather conditions – even those rated Service Class 3. Merbau timber is naturally strong and resistant to rot and termites. Combine this with its industrial strength adhesive and you have an exceptionally strong and long-lasting product.

Quality assurance

Produced by a licensed manufacturer in accordance with Australian Standards AS1328 (which requires manufacturers to maintain third-party audited quality assurance), the Magna Glulam production plants have systems monitored by the Glue Laminated Timber Association of Australia. This involves periodic factory visits and regular structural testing in-house, and by the GLTAA. Magna Glulam is also covered by a 15-year manufacturer’s warranty.

Magna Glulam is considered a hard timber and is well known for its strength. It can easily withstand daily knocks and spills. After testing all timber beams, they were found to be GL17. The Magna Glulam timber posts were also tested and classified as GL17 or GL13.


As mentioned previously, the shrinkage rate of Merbau timber is extremely low (1.5% radial & 2.5 tangential). This allows Magna Glulam to stay straight in various weather conditions and makes it less prone to surface cracking or splintering.

Bushfire resistance

According to the department of agriculture and fisheries on Kwila, Merbau is rated class 1 in timber durability and has a life expectancy of over 40 years for above ground use.

Merbau timber is also considered bushfire resistant (per AS3959-2009), allowing builders to choose Merbau for construction in bushfire prone areas.

Only legal and sustainable timber is used to make Magna Glulam. The forest concession that Magna Merbau is sourced from was one of the first in Indonesia to achieve full FSC Forest Management Certification (CU-FM/COC-857943) and the manufacturing facility holds FSC Chain of Custody Certification (CU-COC-857403) finally to ensure our customers receive a responsibly grown and harvested product Austim also hold Chain of Custody Certification (SCS-COC-005010). All certificate holders are audited by third-party organisations annually to ensure full compliance.

Tannin bleed

It’s important to coat your Merbau timber decking and posts with oil or paint as early as possible. If Merbau is uncoated and comes into contact with water, it can be prone to tannin bleed. Once paint or oil is applied, the tannin bleeding will reduce significantly. Care should be taken if you are installing a Merbau timber product, like Magna Glulam, above or beside light-coloured walls and paving.
