Structural Hardwoods

Structural hardwoods are used for various applications including coastal protection works, civil engineering projects, decking, cladding, street furniture and timber framed homes.
The choice of species for each application is dependent upon its natural properties: Balau, Greenheart and Ekki are all resistant to rot and marine borers - making them suitable for any job where the timber comes into contact with water, whereas Oak is ideal for timber framed houses and street furniture.
