The head of Donaldson Timber Engineering (DTE), Brian Welsh, has decided to leave the business.

The day-to-day running of the roof truss and engineered floors manufacturer will now be assumed by Neil Donaldson, group chief executive of James Donaldson Group.

TTJ understands that DTE Group managing director Mr Welsh, who worked for DTE for 22 years, decided to leave to explore a new commercial venture.

• DTE, the UK’s largest independent roof truss manufacturer, made 112 redundancies in 2008 – 35% of its workforce – due to the construction downturn.
