Hot-dip galvanized steel grille steel grille is currently the most widely used steel grille, with good corrosion resistance, carrying capacity and non-slip performance.In practical applications, according to different use environments and requirements, different types of hot-dip galvanized steel grilles can be selected.This article will compare and analyze the corrosion resistance of the four mainstream types of hot-dip galvanized steel grille steel grilles to help you choose the right steel grille products.

1. Ordinary hot-dip galvanized steel grille, steel grille

The thickness of the zinc layer of ordinary hot-dip galvanized steel grille steel grille is generally between 60-80µm, which has good corrosion resistance and is suitable for general outdoor environments, such as urban roads, garden landscapes, industrial areas, etc.

2. Thickened hot-dip galvanized steel grille steel grille

The thickness of the zinc layer of the thickened hot-dip galvanized steel grille is generally between 80-120µm, and the corrosion resistance is better than that of ordinary hot-dip galvanized steel grille. It is suitable for environments with strong corrosion resistance, such as coastal areas and chemical areas.

3. Hot-dip galvanized + plastic-sprayed steel grille, steel grille

Hot-dip galvanized + plastic-sprayed steel grille Steel grille is based on hot-dip galvanized and then sprayed to form a layer of polyvinyl chloride (PVC) or other plastic coating, which has stronger corrosion resistance and weather resistance. It is suitable for extremely harsh environments, such as seaside, chemical plants, etc.

4. Hot-dip galvanized + electrostatic powder spraying steel grille steel grille

Hot-dip galvanized + electrostatic powder spraying steel grille steel grille on the basis of hot-dip galvanized, and then after electrostatic powder spraying treatment, a layer of polyester resin coating is formed, which has good corrosion resistance, weather resistance and decoration. It is suitable for places with high appearance requirements, such as building facades, railings, etc.
