Metalwork or metal structures - building structures used as carriers in the frames of buildings and other engineering structures (mainly steel structures) in large-span coatings, wall cladding and roofing panels (aluminum structures).

The first metal structures appeared in the middle of the XIX century. In 1851, a steel and glass building was built (world industrial exhibition in London) for the first time in architectural practice. The 300-meter Eiffel tower in Paris became an architectural monument. Today, metalworks are widely used in construction. It can be qualified by size, method of manufacture, configuration and principle of operation. Depending on the method of manufacturing a metal may be cast, forged, spot, riveted, pressed, welded or combined: classwarning, stamp welded etc.
Metalworks have a number of advantages:
less weight than reinforced concrete structures,
production simplicity and seriality,
easy installation and disassembly,
convenience and speed of construction,
possibility of installation in large blocks,
transportability,
strength and durability,
operational reliability.
However, the susceptibility of steel structures to corrosion necessitates their protection from external influences in the form of galvanizing, applying other protective enamel or polymer coatings (painting). Along with reinforced concrete, metalworks are often used in special facilities, heat and gas supply and ventilation systems, oil facilities and systems.
