Koppers Logs, H3 H4 Treated Pine Logs, Pine Sleepers

Pine is widely planted in Australia and New Zealand and is popular in all types of construction and decorative uses. These include framing, lining, glue laminated beams, veneer and plywood. It can be used for many exposed structural and non-structural applications if it is treated with the right protective coating. The texture of pine is fine and knots are very common. The timber is white to pale yellow and the grain is usually straight and is quite easy to work.  Pine is not resistant to termites and can be preservative treated to increase its durability.

Pine plantations are set to become the main source of timber in Australia. Pine can be used in a wide range of applications, including as a domestic and commercial structural timber, flooring, lining, furniture, panels (such as veneer, plywood, particleboard, fibreboard, toys, poles, posts, sleepers, mining timbers (treated), landscaping, pulp and paper.
