Features of Bangkirai Yellow Balau decking

  • Bangkirai (Yellow Balau) is sought after for its immense durability.
  • It is generally considered to be reliable and hard.
  • You can choose from two appearance variations.
  • It is very resistant to water.
  • We supply with Reeded/Grooves profile because it is designed to allow airflow under the boards to stop moisture and mold growth.
  • We supply with standard & better quality.

Bangkirai Origin

Our Bangkirai Yellow Balau hardwood, renowned for its exceptional quality and durability, originates from Indonesia.

Bangkirai (Yellow Balau) Description

Yellow Balau is a tropical wood commonly used for exterior decking. The wood is yellowish-reddish brown and ranges from durable to very durable. Bangkirai is used in freshwater construction, making it suitable for boat decking.
The interlocked grain makes Bangkirai hard to work. Bangkirai has a natural hardness that blunts the effect of tools. That's why buying finished Yellow Balau can be advantageous.
The wood is readily available, making it more cost effective than other tropical woods.

Bangkirai Treatment

We recommend that Bangkirai decking be waxed on all edges before installation - Osmo Wax for Cutting Edges No. 5735. If you decide to finish your Bangkirai deck, you can do so after approximately three months of direct exposure to the elements.

If you choose not to finish the deck surface, a gray patina will develop. Graying is caused by sunlight and water. The main component of radiation that causes wood to turn gray is UV radiation. The wood molecules absorb this radiation. Radiation and water create a gray patina on the surface and in the depths of the wood. This gray patina eventually becomes a natural protection against further exposure to UV radiation. To get to know the price of yellow Balau terrace, please email export@au-mex.com

How Bangkirai wood behaves

Wood is a hygroscopic material, which means that it changes shape depending on the humidity. Depending on the humidity and the ambient temperature, this process of moisture change is reversible, but does not occur in the same plane. For the same relative humidity and air temperature, the wood moisture during desorption is higher than during absorption, with a range of relative humidity RH 30% - 90% by 2.5% to 3.5%. This means that the wood loses volume during drying and does not return to its original dimensions when the moisture is removed. This fact fundamentally influences the behavior of the Bangkirai terrace in the kiln-dried state.

Bangkirai Recommended dilatations

There are changes in humidity and long-term rain, snow, melting snow ...), and boards will increase their sizes in this period, but by 2.5 - 3.5% of their current width. It should also be noted that the terrace boards are cut in different orientations to the trunk axis, tangential, radial and semi-radial, which affects the drying in dimensional percentages. Therefore, there are always different dimensions in the gaps between the boards laid with the same expansion.
