Meranti (red)

The colour of Meranti heartwood varies sharply from dark red to light red-brown and from pale pink to pink-red. Given the diversity of tree types and their region of origin, for the Shorea red meranti species there will always be differences in shades and weights in a delivery of timber. The pink grey sapwood is 20-50 mm thick and distinct from the heartwood.
