Merbau, otherwise known as kwila, is a hardwood with a high tannin content and an abundance of natural oil, making it a popular timber choice for screening and outdoor applications. It seasons well with kiln or air-drying, exhibiting only a low degrade and very little shrinkage or movement.

What is GL13 structural grade?

When graded as GL13, it means the timber is structurally graded to meet strict standards for strength and durability. The stability of merbau and its low shrinkage properties, means it is less likely to warp or twist over time.

As with most natural timber products, colour variation within the merbau timber species is normal and one of its most appealing characteristics. Typically a dark reddish-brown in colour, occasionally a yellowish-brown, merbau exhibits an interlocked or wavy wood grain, coarse but even in texture. It’s a versatile timber that agreeably takes various finishes – stain, oil, clear coat, paint or polish.

Classed as a fire retardant species, structural merbau is naturally resistant to termite attack and decay. Renowned for its enduring qualities, the average life expectancy of merbau with proper above-ground installation and regular maintenance is 25-50 years.

Merbau can be susceptible to tannin bleed, appearing as a red-brown stain, but this is easily removed by cleaning. It also tends to split unless pre-bored, but holds fastenings well.
