摘要：
A prefabricated metal beam is constituted at least of two reinforcing elements each comprising at least one lower member destined to take up tensional stresses, at least one upper member destined to take up compressive stresses and intermediate members for the absorption of shear stresses. Said reinforcing elements are disposed parallel to one another and are connected rigidly by said intermediate members.
