ã€China Aluminum Network】 1) Corrosion resistance: Aluminium-zinc plate has strong corrosion resistance, normal service life up to 25 years, 3-6 times longer than galvanized sheet, and suitable for stainless steel. The corrosion resistance of the aluminum-zinc plate is derived from the maintenance function of the aluminum barrier layer and the maintenance function of the zinc. When zinc is used for dedication in trimming, scratches, and scratches, aluminum forms an insoluble oxide layer that acts as a barrier to maintenance. Aluminum-zinc alloy steel coils have been subjected to outdoor exposure tests for more than 20 years in a variety of different atmospheric environments, confirming the trimming maintenance function of plated 55% aluminum-zinc steel plates, compared with galvanized steel plates and 5% aluminum-zinc steel plates Better.
2) The heat-resistant aluminum-zinc plate has a high thermal reflectance and is suitable for roof materials. The Al-Zn alloy steel plate itself has excellent heat resistance and can be used in high temperature environments up to 315 degrees.
3) Recoatability (film adhesion) The aluminum-zinc plate can maintain excellent adhesion with the paint film, and can be sprayed or dusted without special pre-treatment.
4) Corrosion resistance after painting. After the aluminum-zinc plate is baked by local coating, there is little corrosion resistance when it is not painted. The function is much better than the electroplating of color zinc and galvanized sheet and hot galvanized sheet.
5) Machinability (shearing, stamping, spot welding, seam welding) The galvanized steel sheet has outstanding processing functions, and can perform punching, shearing, welding, etc., and the coating has adhesion and impact resistance.
6) Conductivity. The surface of aluminum-zinc plate covered by special wax treatment, the data conductivity is not affected at all, and can fully meet the needs of electromagnetic shielding.
