Timber carcassing, general purpose building timber.

- Machined from 47 x 175mm, finished size approx. 45 x 170mm
- Smooth regularised finish
- Grade C24
- Good quality, slow-grown softwood
- Pressure-treated green

Our carcassing timber is pressure-treated for extended lifespan and protection against insect and fungal attacks.

Sourced from responsibly managed forests in Europe, the majority of our carcassing is milled in Sweden or Latvia where due to the colder climates the timber is slow grown resulting in a denser, straighter end product.
