Timber Engineering Services and Roof Trusses throughout the UK

Donaldson Timber Engineering Ltd

We provide our clients with construction services for their building developments. Whether you are a self builder or a building contractor, we are able to provide advice; design the best roofing or flooring solution for you; and take your project from design through to manufacture and supply.

We manufacture a comprehensive range of timber roof and floor products, all made from sustainably sourced timber, and all designed to make life easier and safer for the builder.

Our team continues to pioneer new methods of manufacture, which allows us to make the process the most efficient it can be.

Design Engineering

We employ more than 50 design technicians who provide detailed designs. These are then forwarded on to the clients for their acceptance prior to manufacture.

DTE provides the full package in terms of timber engineering, with dedicated design technicians, fully supported by MiTek and Metsä Wood’s in-house engineers, to ensure the best products and service.

Delivery Services

Our products are made to order and require dimensional and engineering approval prior to manufacture. Following approval we can agree your delivery requirements potentially avoiding the need for you to store bulky items until you are ready to install them.

We are market leaders in Health and Safety systems, in particular for our delivery methods. DTE has initiatives in place to improve safety in the delivery and installation of trusses. The system includes Trojan Horse pictoral images, to warn lorry drivers of the dangers associated with offloading trusses, and key to this safer system is that DTE can supply trusses pre-slung with sacrificial/one use slings. The slings enable the trusses to be lifted from the lorry directly onto the roof or storage area, without anyone needing to get onto the back of the lorry and risk falling from height. The system has been acknowledged as best practice by the HSE.



SafeStep is an award-winning scaffolding system for improving safety on-site, designed to minimise risk when fixing ridge bracing on tall roof trusses.
