ST44 Quality Sheet Metal Slab is a flat steel in the form of rolls or sheets with thicknesses ranging between 1.50 - 20.00 mm, which is obtained by hot rolling the rectangular cross-section semi-product, which is formed as a result of solidification of liquid steel by continuous casting technique, in a hot rolling mill.\n\nST44 Quality Steel Sheet Black steel sheets are flat steels produced by hot rolling. They are the most produced and consumed products in Turkey and in the world. Especially in developed and developing countries, production and consumption are increasing every year. The usage areas of black sheets are very wide.<\/p>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
