Galvanized steel is a surface treatment technique that coats a layer of zinc on the surface of a metal, alloy or other material for aesthetics, rust prevention, and the like. The main method used is hot-dip galvanizing. Zinc is easily soluble in acid and soluble in alkali, so it is called an amphoteric metal. Zinc hardly changes in dry air. In moist air, a dense zinc carbonate film is formed on the zinc surface. In the atmosphere containing sulfur dioxide, hydrogen sulfide and marine, the corrosion resistance of zinc is poor, especially in the atmosphere containing high temperature and high humidity containing organic acid, the zinc coating is easily corroded. The standard electrode potential of zinc is -0.76V. For steel substrates, zinc coating is an anodic coating. It is mainly used to prevent corrosion of steel.
Galvalume steel is also called Aluminum-Zinc Alloy Coated Steel,aluminized zinc steel(aluzinc steel),SGLC,The galvalume metal is composed of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at 600 ~C. Its whole structure consists of aluminium-iron-silicon-zinc, forming a compact quaternary crystal alloy.The surface of the galvalume steel sheet is characterized by smooth, flat and gorgeous stars, and its base color is silver white. The special coating structure makes it have excellent corrosion resistance. The normal service life of galvalume steel sheet is up to 25a, and its heat resistance is good. It can be used in high temperature environment at 315 C. The adhesion between coating and paint film is good, and it has good processing performance. It can be punched, sheared and welded. The surface conductivity is very good.
PPGI & PPGL(prepainted galvanized steel & prepainted galvalume steel also known as pre-coated steel or color coated steel coil is a product made of hot-dip galvanized steel sheet, hot-dip galvalume steel sheet, electro galvanized steel sheet, etc. after surface pretreatment (chemical degreasing and chemical conversion treatment), one or several layers of organic coating are applied on the surface, and then baked and solidified.Color-coated steel coil has light weight, beautiful appearance and good anti-corrosion performance, and can be directly processed.
Cold rolled steel is produced by cold rolling. Cold rolling is a steel plate that further thins the No.1 steel plate to a target thickness at room temperature. Compared with hot-rolled steel sheet, cold-rolled steel sheet is more precise in thickness, smooth and beautiful in surface, and has a variety of superior mechanical properties, especially in processing performance.It is mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commerce. Among them, the construction industry is mainly used to manufacture anti-corrosion industrial and civil building roof panels, roof grilles, etc. The light industry uses them to make household appliances shell, civil chimneys, kitchen appliances, etc. The automotive industry is mainly used to manufacture corrosion-resistant parts of cars, etc.
Pressed corrugated steel sheet (roofing sheet) refers to the steel sheet formed by cold pressing or cold rolling. The steel sheet is made of coloured steel sheet, galvanized steel sheet, stainless steel sheet, aluminium sheet, anticorrosive steel sheet or other thin steel sheet. The profiled steel sheet has the characteristics of light weight, high strength, low price, good seismic performance, fast construction and beautiful appearance. The corrugated metal is a good building material, mainly used for guardrail, floor and other buildings, such as airport terminal, railway station, stadium, concert hall, grand theatre, etc. According to different application requirements, the profiled steel sheet can be pressed into a wave type, a T type, a V type, a rib type and the like.
Tinplate (SPTE), also known as tinplate, is a tin-plated iron sheet on both sides, which is a cold-rolled low-carbon steel sheet that is rust-proof, corrosion-resistant and non-toxic. Mainly used in the production of metal packaging, including canned food, beverages, chemicals, medicine, hygiene, paints, paints, sprays, cosmetic bottle caps, etc.
SuperDyma is a new type of highly corrosion-resistant coated steel sheet with a coating composition consisting of zinc as the main substrate in combination with aluminum (about 11%), magnesium (about 3%) and a trace amount of silicon.Adding Al, Mg, and Si to SuperDyma, the composite effect of these added elements improves corrosion resistance.Compared with hot-dip galvanized steel sheet and hot-dip galvanized-5% aluminium alloy steel sheet, SuperDyma has less adhesion but equal corrosion resistance. In addition, it can be used instead of stainless steel or aluminium sheet because of its excellent red rust resistance.
Electrolytic chromium coated steel also called Tin Free Steel(TFS) is an electrolytic chrome plated steel consisting of a thin layer of chromium and a layer of chromium oxide deposited on the steel base.It has a beautiful, metallic luster as well as excellent properties in corrosion resistance and paintability.
In metallurgy, stainless steel also known as inox steel or inox, is a steel alloy, with highest percentage contents of iron, chromium, and nickel, with a minimum of 10.5% chromium content by mass and a maximum of 1.2% carbon by mass.
