Machine Round Pointed Post UC4 Treated Green Redwood Kiln Dried FSC

These redwood round pointed posts are a fantastic multipurpose feature for garden and landscaping projects. Popular within the agriculture market but also great for making borders or sections within most gardens. Classified as UC4, these Machine Round Pointed Fence Posts are suitable for permanent contact with the ground outdoors. It’s no secret that UC4 treated softwood is the best choice for timber garden products. The treatment process involves kiln drying the timber down to around 28% moisture content before treatment, allowing it to penetrate deep into the wood. Without this intense kiln drying, water in the timber will prevent as much treatment getting into the material which makes it unsuitable for garden use. The timber is imported redwood which is naturally durable and requires no incising as redwood will allow treatment to penetrate the outer sapwood with the inner heartwood being naturallly durable anyway. Pine typically has the largest proportion of treatable sapwood than most widely available species. The high pressure treatment cycles we use are optimised to treat the Pine sapwood and force the preservative deep into the cells of the wood structure, providing protection against fungal and insect attack, where it matters most. In UC4 (ground contact) applications, where checks and splits may occur in service, it is crucial that the entire sapwood is treated, to prevent premature failure. Pine heartwood is naturally more durable and resistant to decay organisms than the sapwood, due to the resins deposited during growth. To prolong the life of the board, try to avoid reworking treated timber but where this is unavoidable always retreat the newly exposed surfaces with two liberal coats of end grain preservative. Wherever possible, try not to penetrate the preservative 'envelope' with fixings. It is always advisable to not install in permanently wet or boggy ground. If setting UC4 posts in concrete, suitable drainage or run off arrangements must be incorporated to allow water to flow freely away from the post.
