Q:What are the differences between galvalume steel sheet and galvanized steel plate?

The differences between them are mainly in two aspects. On the one hand, the two mean different things. Aluminized steel plate is a steel plate with a layer of pure aluminium or an aluminium-silicon alloy containing 5% to 10% silicon on the surface of carbon steel. Whereas an galvalume steel sheet is a steel plate with an aluminium-zinc alloy overlay treatment on the surface of the plate, consisting of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at a high temperature of 600°C. It is therefore an alloy coated steel sheet with a dense quadruple crystalline structure formed by the elements aluminium-iron-silicon-zinc. On the other hand, the characteristics are different. Aluminised steel plates have unique properties such as good corrosion resistance, heat resistance and thermal radiation. The galvalume steel sheet has a number of excellent characteristics: corrosion resistance, heat resistance, heat reflection and economy.
