Expert engineered timber.

Donaldson Timber Engineering Ltd (DTE) is the UK's largest and longest established manufacturer of structural timber components, with nine manufacturing sites across the UK and over 30 years of experience.

At DTE we supply a full range of engineered timber products, including roof trusses, open web joists, and I-joists. All of our products are made using legal and sustainably sourced timber - which is one of the most environmentally-sound standard building materials.

As a family owned and run business, at DTE we have strong traditional and family values which are cemented in the business. However, we continue to progress through product development and innovation to offer our customers only the best quality and service. Although we distribute nationally, DTE's coverage means we can provide a local service - something that is key to good customer relationships.

We are market leaders in Health and Safety systems and offer a variety of engineered timber solutions that are used widely across the construction industry.
