Difference between galvalume plate and galvanized plate
Author:
1. Different materials
Galvanized plate: in order to prevent the surface of the steel plate from being corroded to prolong its service life, a layer of metal zinc is coated on the surface of the steel plate.
Aluminized zinc plate: the surface is unique smooth, flat and gorgeous star flower, the base color is silver white. Its surface coating is made up of 55% aluminum, 43.4% zinc and 1.6% silicon.
2. Different service life
Special coating structure makes it have excellent corrosion resistance, the normal service life of aluminized zinc plate is 2-6 times of ordinary galvanized plate. 3, galvanized plate is mainly used in the construction industry, light industry, agriculture and fisheries, and aluminum zinc plate is mainly used in the construction industry, automobile, household appliances and other aspects.
Characteristics of galvalume plate
1, corrosion resistance: aluminized zinc silicon plate is better than galvanized plate in atmospheric corrosion resistance and damp gas corrosion resistance, can be used in all kinds of internal and external building materials and parts.
2, good economy: lower than the production cost of galvanized and aluminum plate.
3, thermal reflection: the thermal reflectivity of aluminized zinc steel plate is very high, twice that of galvanized steel plate, and people often use it to do insulation material.
