If our customers require a specific timber for a project we offer a variety of hardwoods, with Sapele and Iroko being the most commonly used for paint finishes. We also manufacture in European oak using two grades, joinery grade which has minor defects mainly being knots which is ideal for customers who are refurbishing period properties and looking to retain character. The alternative is a prime grade while still retaining some knots generally has cleaner grain in appearance and is perfect for a modern look.
