What is alyumotsink?

It is known that raw steel sheet, which is used outdoors or in contact with moisture, rust. For many centuries people have sought ways of protecting steel plate from the appearance of rust. One of the most popular ways - zinc coated steel sheets. Zinc provides good protection against corrosion and at the same time has the unique characteristic of cathodic protection trim edges and scratches on the fiber. Aluminium - is one more suitable for this stuff, thanks to its extremely low susceptibility to corrosion of Stepney. Thus, an alloy of aluminum and zinc (aluzinc) is optimal. In such an alloy steel plate protects the aluminum from corrosion due to its anti-corrosion properties, while zinc does protect trim edges and protect against scratches. This idea formed the basis for the development of the company Bethlehem Steel (USA), which in the early 60's has patented a special alloy of aluminum and zinc. Already since 1972, this invention has been a source of profit. Aluzinc has been used largely in Europe, America, Asia, Australia and Africa. At this time it was produced and sold about 35 million tons of production aluzinc. As the fastest-growing production, the technology of coated steel sheets 55% aluzinc recognized by almost all leading companies in the world. During the entire development was obtained unadulterated parent rock aluzinc: 55% - aluminum, 43.5% - zinc, 1,5% - silicon. After long-term atmospheric effects in different environments aluzinc structure proved to be the best protection against corrosion. What is the advantage of 55% aluzinc from other types of coatings? Corrosion protection - steel sheet coated with 55% aluzinc two to four times the durability of galvanized sheet. Cost - in investing in such materials as 55% aluzinc, which has a long useful life, require minor repairs and maintenance, as well as a high quality, total cost of construction is the minimum possible. Economic cost calculation shows that the life-cycle cost 55% aluzinc, compared with other building materials, extremely low. Visual appeal - 55% aluzinc has a smooth surface with a silver sheen. Protection from high temperatures - sheets, covered 55% aluzinc can be used at temperatures up to 315 Gy without fading. Ability to reflect heat - 55% aluzinc able to reflect much of the heat and light. For the roof it serves as protection from the heat, acts as a thermal barrier. Usually 45% of the heat goes into the building through the roof and walls. 55% aluzinc reduce this figure in half. Benefits - Aluminum makes up 55% by weight, but 80% of the volume. Special passivation - in addition to conventional etching is a special organic mordant, which improves the characteristics of the sheet coated with 55% alyutsinka.Eta special passivation protects the surface from abrasion and gives the product a seamless alignment. Susceptibility to paint - steel sheets coated with 55% aluzinc have the best surface for painting, regardless of leaf shapes: relief or direct. The optimum alloy - zinc component coating provides additional protection for sheet steel in his unprotected locations, such as cuts, while the aluminum component offers long-term barrier protection. Their combined effect gives a coating with the best protection against corrosion in comparison with other coatings. Silicon is added to obtain the correct reaction between alloy and steel sheets, as well as to ensure that the welding line between the steel and alloy layer is very thin, providing good adhesion and forming properties. The longest service life - steel sheets coated with 55% aluzinc serve two to four times longer than galvanized sheet: in the countryside, in urban settings and in the maritime environment. In the industrial zones of the life of more than six or seven times. Covering 55% aluzinc not subject to corrosion under the influence of the atmosphere in 30 years even in harsh coastal environment. Roofs covered with 55% aluzinc show excellent quality in 25 years even under the acid rain in the coastal environment in the U.S.. All these features prove once again why the firm Bathlehen Steel patented just such a fusion.
