Product overview
Product overview
Mixed hardwood KD F27 in 120 x 35mm is a kiln-dried structural timber section suited to high-strength framing and load-bearing applications where improved stability is required. The F27 stress grade is specified for structural members to design, while kiln drying helps reduce movement compared with unseasoned timber for more predictable straightness and fixing. Mixed hardwood is supplied with a durability classification dependent on species mix and intended exposure, and must be detailed and used in accordance with relevant standards. Use compatible fixings and connectors suited to the environment, pre-drill near ends where required, seal cut ends after trimming, and store flat, dry and ventilated before installation.
