Steel is actually a kind of iron which contains carbon.
Because iron is a pure metal, it is very soft and usually cannot be used directly as engineering materials. And the way to make it harder is to add carbon to turn iron into steel.
There are many different types of steel, and different elements can be added to give steel different properties.
Most steels contain essentially manganese, phosphorus, sulfur, silicon, oxygen, nitrogen, and trace amounts of aluminum. The hardness, ductility, strength and other properties of steel can be affected by the addition of nickel, chromium, manganese, titanium, molybdenum, boron, niobium and other metals.
The addition of more than 13% chromium can improve the corrosion resistance of stainless steel. Another way to increase the corrosion resistance of stainless steel is to plating the metal into zinc steel (usually carbon steel) by electroplating or hot dipping the metal into zinc.

Galvalume Steel Coil is a kind of Alloy-Coated Steel Sheet widely used in building materials, household appliances,automobiles, environment, machinery, ships and many other fields. The surface coating of galvalume steel sheet is composed of 55% aluminium, 43.5% zinc and a small amount of other elements. 1. Heat reflectivity: Aluminum-coated galvanized steel sheet has a high thermal reflectivity, which is twice as high as galvanized steel sheet. It is often used as insulation material. 2. Heat resistance: Aluminum-zinc alloy steel sheet has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. 3. Corrosion resistance: The corrosion resistance of aluminized and galvanized steel coils is mainly due to the protective function of aluminium and aluminium. When zinc is abraded, aluminium forms a dense layer of alumina,which prevents further corrosion of corrosion-resistant substances. 4. Economy: Because the density of 55% Al-Zn is smaller than that of Zn, the area of galvanized steel sheet is more than 3% larger than that of galvanized steel sheet under the same weight and thickness of gold plating. 5. Easy to paint: Aluminum-coated galvanized sheet and paint have excellent adhesion and can be painted without pretreatment and weathering treatment. 6. Aluminum-galvanized steel sheet has a silver-white gorgeous surface.Read more
