Galvanized sheets are construction materials that are very much in demand; they are such materials, which are notable for their high quality, reliability and durability. They are widely used in industrial and civil construction due to their two main qualities, namely their resistance to corrosion and good outer appearance. Galvanised steel, particularly galvanised sheets, is very often used in manufacturing metal structures. It is also important to note that galvanised sheets become the basis for rolled metal products of various types. Strips, squares and circles are cut from them. The material used to manufacture galvanised sheets is carbon cold-rolled coiled steel.
