Plywood is a versatile building material with applications in many interior and exterior surfaces. It is one of the most durable materials available and it can provide an excellent foundation for your building. We have been providing the best quality plywood for over 55 years. All the timbers that we use are hand-picked from forests across the world. These timbers are seasoned and chemically treated to make our plywood durable, long lasting and resistant to termites and borers. These then undergo a unique THT treatment, a technique that ensures optimum treatment of moisture.
