1. The galvanised coating provides complete coverage of all steel surfaces and acts as a barrier protecting the steel from the surrounding environment.
2. The galvanised coating cathodically protects the steel from coating imperfections caused by accidental abrasion, cutting, drilling, or bending.
3. The zinc patina is insoluble and passive, which slows the corrosion rate of the zinc. The zinc patina is a critical part of the galvanised coating’s longevity and requires natural wet and dry cycles to form.
