treatment process
Wespine has a range of preservative treated products for use in outdoor constructions. For use in external or below ground applications, Supapine is treated to H3 or H4 in accordance with AS1604 - 2000. With the exception of fencing and lattice, all Supapine is kiln dried after treatment. Structural sizes are machine stress graded in accordance with AS1684-1999.
Light, durable and easy to use, the strength of Supapine timber allows for a wide variety of projects. Visit our DIY Centre for inspiration on home handyman ideas!
