What is sawn treated carcassing timber

Carcassing timber is kiln-dried treated structural graded softwood that is most commonly used where a grading stamp is required. Predominantly used in the construction of floor joists, roof joists and timber framing, it can also be used in many other applications both internally and externally.

WEL BM keep our timber indoors to minimise shrinkage/expansion of the timber planks due to weather variations and away from direct sunlight.

All of which provides the end user with a product that is fit for purpose.

C24 timber is roughly 50% stronger than C16 timber, so is better suited to longer spans or heavier loads, so a C16 timber joist will not be able to bear the same load weight as a C24 timber joist.
