47 x 175mm (7x2) Carcassing Timber

Carcasssing 47mm x 175mm Kiln Dried, Stress graded C24 stock in Devon

Our carcassing stock is strength graded C24. It is supplied by an established importer. The timber is planed-all-round for consistency and easy handling. Quality is high and supply from Sweden is reliable and consistent. All carcassing stock, except some CLS, is pressure treated a nd is signified by a light green colouration.

Carcassing stock section sizes

We keep large quantities of 47mm x 175mm carcassing while aiming to rotate stock as quickly as possible. Incoming carcassing deliveries from Scandinavia are received on a regular basis. Please note that because the imported timber is regularised and planed all-round most of our timber is now 45mm

Most architects now specify C24 graded timber because of the longer spans available. This means that these timbers have to be imported. Our UK home-grown timber grows too quickly to achieve C24 grade.

Carcassing timber stocks are environmentally certificated, unless marked otherwise. We sell both FSC and PEFC certified timber. Both organisations are dedicated to promoting sustainable forest management. The process includes independent timber audits and third-party certification

The uses of carcassing timbers

Our carcassing timbers are Kiln Dried (KD) which gives them improved dimensional stability. All our carcassing is planed and regularised for a smooth and consistent finish. This makes the timber more pleasant to handle than most sawn carcassing. The finish is very similar to CLS timber. All of our carcassing timbers, with the exception of some CLS, is supplied pressure treated.

Popular uses for carcassing include floor joists, ceiling joists and roof rafters. The pressure treated (aka tanalised) carcassing is also used for decking joists and studwork. If these are exposed then further preservative treatment is advised to prolong service life. Again, for limited-protection timbers, a tin of Ronseal End Grain protector should be applied to any cross cuts in pressure treated timber.
