With flat steels in the form of rolls or sheets, the thickness of which varies in the range of 1,50-20,00 mm, obtained by hot rolling the semi-product of rectangular cross section, which is called slab and is formed as a result of solidification of the liquid steel by continuous casting method, in the hot rolling mill, ,00-200.00 mm. They are flat steels in the form of plates with a thickness between 1,000 and 3,800 mm.

General structural steels, which can be welded by conventional methods and whose mechanical properties are guaranteed, ductility and toughness optimization are provided, are mostly used in the manufacture of construction machinery and work machines, general construction plates, land and railway vehicles manufacturing, storage tanks and container manufacturing.

Hot rolled tubular steels; With its high strength, excellent toughness and good weldability properties, it is used in the production of pipes suitable for water/oil or gas/oil transport.

Boiler steels suitable for use under high temperature and pressure are used in the manufacture of pressure vessels and boilers, in the production of pipes exposed to pressure and steam, in the manufacture of industrial thermal vessels and heat exchangers, due to their excellent forming and weldability properties.

Tube steels; With its high formability, excellent weldability and toughness properties, it is used in the manufacture of LPG cylinders where safety is very important.

Medium and high strength shipbuilding steels, which provide superior weldability and desired toughness values, are used in the interior and keel of the ship.
