Before you order carcassing timber
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.
Cut ends
Treat any cut ends with a suitable end-grain preservative, especially on external work.
Wales has its own Approved Documents, including its own Part L for energy efficiency, and building control is handled by the local authority or a registered approver.
Working out quantities for your Cardiff job
A floor 4.2 m wide with joists spanning 3.6 m at 400 mm centres needs 12 joists, plus trimmers and noggins. The section and grade, such as 47 × 200 mm C24, come from span tables or your engineer; send us the timber schedule and we will price it.
Before your Cardiff delivery arrives
Timber is delivered in packs or bundles on a flatbed; long lengths need clear access along the drop point. Cardiff is inside our standard mainland delivery area.
- If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
- Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
- On busy streets in Cardiff, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
Ordering carcassing timber for Cardiff: FAQs
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.
Is there a minimum order for delivery to Cardiff?
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.
Can you deliver carcassing timber to a site with restricted access in Cardiff?
Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.
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.
