Shortage of steel has agaln helped the development of light alloys for structural work. The London County Council, which controls all building in the met- ropolis, has given "conditional" permission for the construction of

Main Difficulty

The main difficulty facing the nuthorities, who pre responsible for laying down permissible working stresses, is that there are so many aluminium alloys, each with widely differing properties, Prefabricated aluminium roal trusses have been on the market for some time, and examples of
