Publisher History

BM TRADA originates during the 1930s when a forerunner of what later became the Timber Research and Development Association (TRADA) was set up to promote the use of wood in construction. Their publishing programme delivers an extensive range of timber information - Eurocode 5 guidance, span tables, Wood Information Sheets and technical manuals on timber structures, characteristics, performance aspects such as fire and durability, and common applications.
