The difference between GI steel and GL steel

1. Resistance to atmospheric corrosion: GL(galvalume) steel sheet is excellent, while GI(galvanized) steel sheet is good.

2. High temperature oxidation resistance:GL sheet is excellent, and GI is good.

3. Processing performance: GL sheet behaves well, and GI behaves well.

4. Weldability: GL sheet behaves poorly, while GI behaves better.

5. Coating property: GL sheet behaves better, and GI behaves better.

6. Incision protection: GL sheet behaves poorly, while GI behaves better.

7. Cathodic protection: GL sheet is poor, while GI is strong.
