What is Structural Carcassing Timber?

Often referred to as carcassing timber, this type of wood is most commonly used in structural applications that involve the timber being used in an area that won’t be seen, and typically comes in three gradings:

• C16 Timber
• C24 Timber
• Part Graded Timber

Do I need Treated Structural Timber?

If the timber is going to be placed in an area where attacks from external problems such as moisture or fungal attacks, are likely to cause major problems, then we strongly recommend purchasing treated structural timber.

For all the following applications, we generally recommend using a treated structural timber:

• Roof Rafters
• Timber Framing
• Ceiling Joists
• Floor Joists
• Deck Joists

I need a Sawn Finish Structural Timber

Sawn Carcassing Timber has largely been replaced in UK stockists with “eased edge” stock being introduced in the UK in 2004.

Eased Edged means that the timber is semi-surfaced and finished to a uniform finish that is relatively smooth. Four corners are radiused to reduce the likelihood of splinters.

Most of our branches do hold stock of sawn boards that are either treated or untreated. However, if you require a sawn unsurfaced finish, please contact your nearest branch, who will be able to source this as a special item to meet your requirements. Most sizes can be obtained within 5 to 10 working days.
