Buying timber — what matters
The honest way to judge 100 × 100 H4 Treated Pine Rough Sawn – Heavy Duty Timber Post / Purlin is against the job it has to do, not against the cheapest thing that shares its name.
- Specification over price. Two products in timber can share a description and be built to very different standards. Check the spec table above before comparing prices.

- Lead time. Stock position moves weekly. We confirm availability before you commit, not after.
