Finger jointed Treated Pine is a long, straight and defect free length of timber less likely to twist than a natural piece of timber. H4 Treatment protects against decay, termites and borers and is suitable for use outside and inground.  The CCA treatment is used to treat the timber to the H4 level for exterior ‘in ground’ use for fence posts, landscaping applications, pergola or veranda post application. For structural use, these posts are subject to the specifier following the GL tables and ensuring GL8 is suitable for the proposed application.
