Fitting and handling
Store timber flat and off the ground on bearers, covered and well ventilated, to prevent warping before installation. Kiln dried to 20% moisture content or below, this timber is ready for most site conditions, though allowing a short acclimatisation period in the working environment will further reduce on-site movement. Use hot-dip galvanised or stainless steel fixings with Tanalised timber to avoid corrosive reactions with the preservative treatment.
FAQ
Is C24 graded timber suitable for structural use under UK building regulations?
Yes. C24 is a structural strength grade to BS 4978 and is widely accepted for load-bearing applications including floor joists and roof rafters under current UK building regulations. Always consult your structural engineer or building control officer for project-specific requirements.
Can I use Tanalised 4x2 timber outdoors?
Yes. Tanalised pressure treatment makes this timber suitable for exposed above-ground applications such as decking subframes and outdoor structures. The preservative treatment protects against rot and insect attack, extending the service life of the timber significantly compared with untreated softwood.
