Getting carcassing timber onto your Keighley site

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

• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.

Working out quantities for your Keighley job

A floor 6 m wide with joists spanning 3.9 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.

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.

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 Keighley

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

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.

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.

Can I add other materials to my Keighley 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.
