"Nucleation and growth of 55% Al-Zn alloy on steel

The nature of nucleation and growth of the alloy overlay of a 55%A1-Zn alloy on a steel substrate strongly affects the surface appearance of hot dip metal-coated steel in the Zincalume process. The potential nucleation site of the first nucleus that forms in the alloy overlay will contribute to the initial solidification process and subsequent microstructural development.

1. Metallic-Coated Products and Specifications

The composition of the aluminum-zinc alloy used in 55% Al-Zn coatings has been proven to outlast galvanized steel by two to four times, depending on the environment. Building panels fabricated from 55% Al-Zn alloy-coated steel sheet will provide many years of trouble-free service when properly designed, installed and maintained. AL ZN Alloy Coated Steel Sheet (Al ZN COAT) BARO METAL55% Aluminium Zinc Alloy Coated Steel Sheet. AL ZN COAT is highly heat-and-corrosion resistant, combining the properties of aluminum that render increased durability, excellent heat resistance, and formability, and those of zinc that offer high heat resistance and excellent corrosion protection. AL ZN COAT is three to six times more corrosion
