How much will you need?
A floor 3 m wide with joists spanning 3.9 m at 400 mm centres needs 9 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 Dorset site
Timber is delivered in packs or bundles on a flatbed; long lengths need clear access along the drop point. Our standard mainland delivery area covers Dorset.
- Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
- Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
- Give us the full postcode for the drop point; deliveries around BH are priced to the exact address.
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.
Treated Carcassing Timber in Dorset: questions
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 there a minimum order for delivery to Dorset?
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.
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.
