Difou
Species profile
The wood is yellow brown and has clearly demarcated sapwood. The grain is straight or interlocked and the texture is medium. The colour darkens with air and becomes brown. Difou is similar to Iroko.

The blunting effect is fairly high; peeling is reported to be bad and slicing is reported to be good. Requires power. Nailing is good but pre-boring is necessary. Gluing is correct. Difou dries normal to slowly.

Difou is very durable to fungi and is durable to dry wood borers; sapwood demarcated (risk limited to sapwood). This species naturally covers the biological hazard class 4 for building.

Difou can be used for several applications:
• interior: e.g. high class furniture, stairs, sliced veneer, paneling, sculpture, flooring, joinery, industrial or heavy flooring
• exterior: e.g. sleepers, bridges, ship building, panelling, joinery, heavy carpentry, stakes, posts, vehicle or container flooring
