Treated Carcassing Timber: choosing well

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 England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.

Working out quantities for your Nailsea job

A floor 6 m wide with joists spanning 3 m at 400 mm centres needs 16 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.

Getting carcassing timber onto your Nailsea site

Timber is delivered in packs or bundles on a flatbed; long lengths need clear access along the drop point. Nailsea is inside our standard mainland delivery area.

• In summer Nailsea gets around 16h 38m of daylight, but early deliveries still beat the traffic and give the longest working day.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• On busy streets in Nailsea, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.

Your questions answered

Is there a minimum order for delivery to Nailsea?

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.

Why is my treated timber green or brown?

The colour comes from the preservative. It fades over time and does not tell you how well the timber is protected; the use class does.

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.

Can I add other materials to my Nailsea delivery?

Yes. Put everything on one list, from carcassing timber to fixings and PPE, and we will price it as one delivery where the products can travel together.
