CONSISTENT

Merbau timber has low shrinkage rates (2.5% tangential & 1.5% radial), which means that Magna Glulam stays as intended in exposed conditions. It also means that Magna Glulam is much less susceptible to cracking and 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.

SUSTAINABILITY

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

One thing to be aware of with merbau timber is that it is prone to tannin-bleed when in contact with water and should be kept dry at all times prior to coating with a deck oil or paint. Once coated, bleeding is significantly reduced. However, care should still be taken when installing merbau timber above or near lighter coloured paving or walls.
