A metal structure, in construction, is a load-bearing system of a building predominantly composed of metal elements. This structure is used in almost all areas of construction: building construction (halls, hangars, garages, skyscrapers, towers, roofs, canopies, chimneys, scaffolding), bridge construction (rail- way, road, pedestrian, pipeline bridges) and hydraulic construction (dams, culverts, pipelines under pressure, caissons), and for transport facilities (cranes, ropeways, crane tracks), storage facilities (reser- voirs, silos, bunkers), mining and metallurgical facilities (drilling and extraction towers, blast furnaces, substructures), poles of various purposes (lighting, power line, antenna, radio and television, radar) and others.
The convenience of using metals for load-bearing structures is based on their high strength, elasticity and plasticity. Among the metals, due to cheap rolled products, steel predominates, while much lighter, aluminum alloys are used when the own weight of the load-bearing structure is of crucial importance. Metal constructions are made from basic elements: supports, rods, lamellas, sheets, pipes and special profiles.
