Things to check before you order

C16 or C24?

C24 is stronger and stiffer, so it can span further or use a smaller section. Span tables and your structural drawings decide which grade and size you need.

Which treatment?

Treatment is specified by use class. Timber inside a building is usually use class 1 or 2; external timber out of ground contact is use class 3; timber in ground contact needs use class 4.

In Northern Ireland building work follows the Building Regulations (Northern Ireland), with guidance in the Technical Booklets, and applications go to the council's building control team.

Getting carcassing timber onto your Belfast site

Timber is delivered in packs or bundles on a flatbed; long lengths need clear access along the drop point. Deliveries to Northern Ireland include a sea crossing, so we quote each order individually.

• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.

Treated Carcassing Timber questions

Is your carcassing timber treated?

We supply treated carcassing as standard for structural work. Tell us if the timber is for external or ground-contact use so we supply the right treatment level.

Is there a minimum order for delivery to Belfast?

There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.

Do you deliver carcassing timber to trades and homeowners in Belfast?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.

What does C16 and C24 mean?

They are strength classes under BS EN 338. C24 timber is stronger and stiffer than C16, which lets it span further for the same size.
