Traditional plywood box beams depend to a considerable extent on the strength of natural timber for their flanges, and for reasons of safety only the highest grade of timber should normally be used, particularly when it is not laminated or when there is an abrupt change of direction at midspan. In this article Professor Bond describes tests which have been carried out in the Civil Engineering Department of the Queen's University of Belfast showing how steel reinforcement may be incorporated to enable such beams to be manufactured competitively with other forms of roof beams in countries where high-grade softwoods are not readily available and labour costs are lower.
