Aluminum zinc corrugated board is made of aluminum zinc steel plate as raw material, processed into corrugated shape by special pressing equipment. Its surface coating is composed of 55% aluminum, 43.4% zinc, and 1.6% silicon, which gives it many characteristics, such as strong corrosion resistance, better than galvanized steel plate, and can be used normally for 25 years; Capable of withstanding temperatures exceeding 300 ℃, with high thermal reflectivity, twice that of galvanized sheet; Good processability, easy stamping and welding, and also convenient for painting. Due to the density advantage of aluminum zinc alloy, with the same weight and coating thickness, the plate area is larger, which has economic advantages and is widely used in construction, industry and other fields.
