Merbau (Kwila) Instsia bijuga:

Overview,

This type of fencing became popular in the last 5 years. We find that it is best used on a steel frame to decrease the issues that come with warping. The material has a tendency to “bleed” when first applied; we recommend that it not be used close to any concrete or paved area where the stain can be an issue. The material comes from South East Asia and the Pacific Islands. It is a hardwood – heartwood and dark brown in colour. The texture is fairly coarse and even. It is good for most above ground external uses.
