Product Introduction

Hot aluminized zinc substrate
Hot aluminized zinc steel plate (55%Al-Zn) is used as the new coating substrate, usually containing 150g/㎡ of aluminized zinc (double-sided).The corrosion resistance of hot aluminized zinc plate is 2-5 times that of hot galvanized plate.Continuous or intermittent use at temperatures up to 490℃ does not result in severe oxidation or oxide skin.The ability to reflect heat and light is 2 times that of hot-dip galvanized steel, and the reflectivity is greater than 0.75, which is the ideal building material for energy saving.
Aluminized zinc color coated coil plate is a new material produced in China in recent years due to high-end applications, commonly referred to as CCLI.It is made of aluminized zinc plate (55% aluminum, 43% zinc and 1.6% silicon) which is more corrosion resistant than zinc plating, after surface degreasing, phosphating and complex salt treatment, coated with organic coating and baked.Examples of products in practical application are as follows: substrate selection: AZ150 (aluminized zinc content 150g/m2;)G345A high strength Aluminum zinc plate (55% aluminum, 43% zinc and 1.6% silicon) corrosion resistance data: 5%NaCL 35℃, 1000Hrs, good Field, Scribe No Blister 2mm below Q.U.V:2000HRS, color difference MAX.2, light retention rate of more than 90%, the above data show that the aluminized zinc color coated plate (AZ150,G345A,PVDF) is very suitable for the construction or other facilities in extreme environment, very corrosion resistance and weather resistance, and this steel plate can ensure more than 20 years of service life.In addition, high strength steel plate has been widely used in foreign countries, with better economy, but also the development trend in China.
