Treated Carcassing

If your project needs timber that can handle the elements, you need to check out our treated carcassing timber. With some of the lowest prices in the North West and best quality you can find, it's no wonder why builders, landscapers, and home improvers alike trust us. Our treated carcass is perfect for everything from decking frameworks and fencing to roof battens, pergolas, and outdoor structures that need long-term strength and resistance to decay.

Designed to Last, Whatever the Weather Throws at it

When timber is exposed to the elements, untreated wood can quickly warp, rot, or weaken. That's why our carcassing timber is pressure-treated for maximum protection. Each piece is kiln-dried, machined, and treated with ACQ preservative to guard against potential insect attack and any fungal decay. By doing this, it ensures your timber not only looks great but is durable for years, even in damp or outdoor environments.
