Donaldson Timber Engineering

We supply a full range of precision-engineered timber products, including roof trusses, open web joists, and site-ready I-joists. All of our products are made using legal and sustainably-sourced timber, one of the most environmentally-sound standard building materials. As part of the James Donaldson & Sons Group of companies, we pride ourselves on our values of always putting customers at the core of everything we do, our integrity, our people, delivering sustainable financial and environmental performance and we embrace the future through our proud family heritage of over 150+ years.

Pre-fabricated Spandrel panels eliminate blockwork at gables and party walls. The speed of build can help you get the building wind and watertight quicker, allowing follow on trades earlier access to complete their work. Floor cassettes are suited to timber frame buildings. Quick installation for these also means that our customers save time and resources on-site.

Our suite of engineered timber products includes roof trusses, open web joists, I-joists, and panels. We only use sustainably sourced timber, that is why our products lead the way in Engineered Timber solutions.

We provide our clients with construction services for their building developments. Whether you are a self-builder or a building contractor, we can give 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.

Our customers and insurers often tell us that the company's internal systems are among the best in the industry, as we have developed leading initiatives to make employees, customers, site workers and haulage drivers safe. As accidents at work in the construction industry continue to make for alarming reading, we have been focused on improving the safety of the industry's biggest risk areas, including working at height and unloading roof trusses. We have put a number of significant safety measures in place to prevent the risks associated with unloading trusses.
