The arches can be made of othermaterial than cast iron such as cast steel or terra cotta, butcast iron is considered the material most available and leastexpensive for general purposes The following claims of meritfor this construction are pointed out: The arches can be made of any dimensions to give therequired strength and of such shape to use most economically themetal in them. Cast iron being much stronger in compression thanin tension, the strength of a floor-plate may be varied consid-erably by a change in the cross section of the plate with veryl
