- Can be supplied raw or precoated with primer, lacquer or special finishes
Our Okoume faced plywood is available on a core of long-grain okoume veneers alternating with another species for the crossgrain veneers (described as ‘okoume combi plywood’), or with just the face in okoume on a core of 100% another species (called ‘okoume twin plywood’).
Typically, okoume is combined with lightweight poplar plywood and the resultant panel described as ‘okoume/poplar combi plywood’ or ‘okoume/poplar twin plywood’.
Due to its lower cost and lighter weight, this contruction is used extensively in the manufacture of vehicles and structures where a lightweight panel is required.
