James Jones was one of the first UK timber processors to introduce stress graded British carcassing to the UK construction industry. Our philosophy was, and remains to this day, to offer the very best in quality products and customer service, consistently.

Our five Scottish-based sawmills retain a high degree of flexibility, while achieving extremely high levels of efficiency due to the on-going investment in the latest timber technology made by the company. 3-D scanning, X-ray grading, mini-bundling and incising are among the latest technological innovations we have introduced to assist and complement high-speed, high volume and high yield production.

We offer an ex-stock capability on a wide range of carcassing specifications augmented by a wide range of complementary specifications.
