Both galvanized sheet and galvalume(aluzinc) sheet have good heat resistance, heat reflection, corrosion resistance, easy to paint and other properties, but all properties of galvalume(aluzinc) sheet are better than galvanized sheet. Its service life is more than four times that of ordinary galvanized steel. It is a replacement product of galvanized sheet.
Sa ki annapre yo se karakteristik fèy galvalume (aluzinc):
Heat reflectivity: The heat reflectivity of galvalume(aluzinc) sheet is very high, twice that of galvanized steel sheet, and people often use it as a thermal insulation material.
Heat resistance: Al-Zn alloy steel plate has good heat resistance and can withstand high temperature of more than 300 degrees Celsius, which is very similar to the high temperature oxidation resistance of galvalume (aluzinc) steel plate. It is often used in chimney pipes, ovens, luminaires and fluorescent lamp shades.
Rezistans korozyon: Rezistans korozyon nan bobin asye galvanised se sitou akòz fonksyon pwoteksyon aliminyòm ak aliminyòm. Lè zenk la chire, aliminyòm nan fòme yon kouch dans nan oksid aliminyòm, anpeche sibstans ki reziste korozyon -de plis korode enteryè a.
Easy to paint: It has excellent adhesion between galvalume(aluzinc) sheet and paint, and can be painted without pretreatment and weathering.
Economical: Because the density of 55 percent AL-Zn is lower than that of Zn, the area of the galvalume (aluzinc) steel sheet is more than 3 percent larger than that of the galvanized steel sheet under the same weight and the same thickness of the galvanizedlayer.
