James Jones & Sons Ltd is the largest manufacturer of I-Joists in the UK. The Company operates two custom built manufacturing lines at its plant in Forres, Morayshire.

The Company has the capacity to manufacture 6 Million Linear Metres of JJI-Joists per annum, equating to approximately 60,000 new houses. The two JJI-Joist production lines offer the most flexible production capacity to its end users and can deliver a highly efficient and effective JIT delivery service. These lines are supported by a state-of-the-art finger jointing line, and web line. The plant currently operates a two shift work pattern, manufacturing 22 hours per day to meet demand and, importantly, to maintain the correct levels of stock profile on the ground for immediate call off.

Quality Control is an integral part of both the manufacturing process and management ethos, and all products are stringently tested in a transparent and audited manner under ISO9001:2008 procedures.

JJI-Joists are manufactured from kiln-dried strength-graded timber flanges and 9mm thick Oriented Strand Board (OSB) webs. All raw materials are sourced from long term supply partners from the UK and Europe, and each of these have undergone rigorous vetting and test procedures.
