1. Understanding Galvanized Steel Sheets

1.1 What is Galvanized Steel?

Galvanized steel is carbon or stainless steel coated with a layer of zinc to prevent rusting. The hot-dip galvanizing process involves immersing steel in molten zinc, creating a protective barrier against moisture and oxidation.

1.2 Types of Galvanized Steel Sheets

- Hot-Dip Galvanized (HDG) Steel: Provides a thick zinc coating, ideal for outdoor use.

- Electro-Galvanized Steel: Thinner zinc layer, suitable for indoor applications.

- Galvannealed Steel: A combination of galvanizing and annealing for better paint adhesion.

1.3 Anti-Corrosion Coatings

Additional coatings such as epoxy, polyester, or fluoropolymer enhance corrosion resistance, making the steel suitable for marine, industrial, and high-humidity environments.

2. Key Specifications for 2mm Galvanized Steel Sheet Rolls

When sourcing 2mm galvanized steel sheets, consider:

- Material Type: Carbon steel (cheaper, strong) or stainless steel (higher corrosion resistance).

- Zinc Coating Thickness: Measured in microns (e.g., Z275, Z350).

- Surface Finish: Smooth, spangled, or matte.

- Width & Length: Standard rolls range from 1000mm to 1500mm in width and vary in length.

- Standards Compliance: ASTM, EN, JIS, or ISO certifications.
