What is the difference between aluminium-zinc plate, galvanized plate, and aluminium-zinc silicon plate?
Zinc aluminum alloy coating plate is also known as low aluminum galvanized steel plate, coating contains 5%Al, 95%Zn, and trace rare earth elements. The main advantage is that the plastic and adhesion of the coating is very good, and the corrosion resistance before and after deformation is unchanged; The atmospheric corrosion resistance is 2~3 times of the conventional hot galvanized sheet and has good coating, welding, in all galvanized sheet, its toughness is very good, corrosion resistance and formability can be comparable with galvanized sheet. The product is mainly used for corrosion and weather resistance environment and coating material substrate.
Aluminum zinc alloy coated plate (GL)
The coating structure of al-Zn alloy coating plate is Al-Zn alloy, and the coating composition is 55%Al, 43.3%Zn and 1.6%Si. Its surface is smooth, with excellent atmospheric corrosion resistance, 2~6 times higher than the same hot galvanized sheet. It has high temperature corrosion resistance similar to hot aluminum plate, and can be used for a long time without any discoloration or deformation at 315 degrees high temperature. Water resistance is better than hot galvanized plate and hot aluminum plate, soil resistance is better than hot galvanized plate. Its thermal reflectance is higher than 75%, twice that of ordinary galvanized sheet. With good coating and processability, is gradually replacing galvanized sheet and widely used in the world.
Hot rolled galvanized sheet
Hot rolled galvanized sheet is based on hot rolled sheet, directly produced by pickling galvanized sheet. The plate can be widely used in construction, automobile, steel warehouse, railway passenger cars, highway guardrail board, etc. At present, hot rolled galvanized sheet in domestic production is less, has been built and put into production of galvanized production lines are based on cold rolled sheet galvanized sheet. Compared with cold rolled galvanized sheet, hot rolled galvanized sheet is not very different in the use of performance, because the hot rolled galvanized sheet saves the cold rolling process, the production cost is lower, has an obvious price advantage
