Ifor Williams Trailers is the United Kingdom's largest manufacturer of trailers under 3,500 kilograms (7,700 lb), based in Corwen, Denbighshire, North Wales.2

The story

Founded in 1958 by local farmer Ifor Williams, an on-site galvanizing plant gives the company total control over quality and efficiency in the production of chassis and other assemblies. The company employs approximately 800 people across six sites in Clawdd Poncen, Cynwyd, Ruthin, Deeside and Sandycroft, Flintshire. During the Great Recession, 63 employees were made redundant in late 2008.

Production was affected by fire on two occasions. The first, on 28 August 2012, caused severe damage to the company's Deeside plant. The second, on 14 September 2017, was limited to machinery at the Clawdd Poncen site.

Production capacity for specialised "Business in a Box" style trailers was expanded in 2021, with the opening of the site on Boundary Park, within the Deeside Industrial Park. This site also functions as the warehouse and worldwide distribution facility for parts.
