Release time:2019-09-09

2.1 55%Galvalume alloy coatings

Aluminum zinc composition control, coating containing 55% aluminum, 43.5% zinc, 1.5% silicon, the alloy products, aluminum zinc products and hot dip galvanized production process is the same.

2.2 55%Galvalume alloy structure

2.3 Characteristic of 55% galvalume alloy coatings

2.3.1Coating characteristics

Corrosion resistance, high temperature oxidation resistance heat reflection, easy to form

2.3.2 Comparison of GI with GL

Corrosion resistance of the same coating thickness: GL =2~6× GI

High temperature oxidation resistance, thermal reflection
