Description ex50 x 150mm Incised Decking Joists Uc4 Tanalised for use as decking beams when constructing your decking base and building decking framework. Incised decking joists can also be used for shed or Timber building bases. These ex50 x 150mm Incised Decking Joists have gone through Tate Fencing’s incising process before being pressure treated. This means we are treating the timber to the best level available. Allowing the treatment to penetrate as deep as possible beyond the surface of the wood. Incising improves protection and should increase the service life of treated wood. Please note: cutting the decking joists would break the treatment seal, so all cuts should be re-treated. Dimensions ex 50 x 150mm Lenght available 3.6m, 4.8m, Tanalised Treated to UC4 (Treated for 10-year life expectancy but NOT guaranteed) The incising process is a series of approximately 8mm deep x 10mm wide slits cut into the surface of the timber, allowing much better penetration for the treatment and to create a complete envelope seal on all faces of the timber.
