Delivering carcassing timber in Harpenden

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

• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.

A quick quantity check

A floor 5.4 m wide with joists spanning 3.6 m at 400 mm centres needs 15 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 the right 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.

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.

Treated Carcassing Timber in Harpenden: questions

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

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.

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 Harpenden 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.
