Delivery to Arnold: what helps

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

• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.

A quick quantity check

A floor 4.2 m wide with joists spanning 3.3 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.

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.

Common questions from Arnold

Can you deliver carcassing timber to a site with restricted access in Arnold?

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.

What sizes of joist do I need?

That depends on the span, spacing, loading and grade. Use span tables or your engineer's design; building control will check.

How soon can carcassing timber be delivered in Arnold?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.

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.
