Galvanized aluminum coil coating for double protection
There are basically two methods for metal coating to protect steel plate substrates from corrosion, namely sacrificial protection and passivation protection.
Galvanized aluminum coil coating because its alloy coating contains both zinc and aluminum, so in addition to zinc can provide sacrificial protection, aluminum also provides passivation protection. Aluminum is very easy to oxidize in the air, and the formed AL203 becomes an extremely dense protective film, which can isolate oxygen, water and other corrosive substances in the air from contacting the surface of the steel plate and play a role of anti-corrosion.
1. Corrosion resistance: Aluminum zinc plated plate has strong corrosion resistance, with a normal service life of up to 25 years, 3-6 times longer than zinc plated plate, and is suitable for stainless steel. The corrosion resistance of aluminized zinc plated plates comes from the maintenance function of the aluminum barrier layer and the dedicated maintenance function of zinc.
2. Heat resistance: The aluminum zinc plated plate has a high thermal reflectivity, making it suitable for use as a roof material. The aluminum zinc alloy steel plate itself has excellent heat resistance, and can be used in high-temperature environments up to 315 degrees Celsius.
3. Recoating property: (Paint film adhesion) The aluminum zinc plated plate can maintain excellent adhesion with the paint film, and can be directly sprayed or powdered without special pre-treatment.
4. Corrosion resistance after coating: After partial coating and baking of the aluminum zinc plated plate itself, the corrosion resistance of the unpainted plate is slightly reduced. Its function is greatly superior to that of galvanized color zinc, electrogalvanized sheet, and hot-dip galvanized sheet.
5. Machinability: (shearing, stamping, spot welding, seam welding) Aluminum zinc plated steel plate has outstanding processing functions, capable of stamping, shearing, welding, etc. The coating has excellent adhesion and impact resistance.
6. Conductivity: The exterior of the aluminum zinc plated plate can meet the requirements of electromagnetic shielding through special waxing treatment.
