Q235 Galvanized steel plate is a high-quality low-carbon structural steel plate that has been coated with a protective layer of zinc through the hot-dip galvanizing process. This combination provides an excellent balance of strength, formability, and, most importantly, exceptional resistance to corrosion. The "Q235" designation indicates a yield strength of 235 MPa, making it a versatile and widely used material in numerous industries.

Our galvanized steel plates are manufactured to stringent international standards, including ASTM A653 (coating) and GB/T 700 (base material, equivalent to ASTM A36), ensuring consistent performance and reliability.

Key Features & Advantages

Superior Corrosion Resistance: The zinc coating acts as a physical barrier and provides sacrificial (cathodic) protection to the underlying steel, preventing rust and significantly extending the product's service life, even in harsh environments.

Excellent Strength and Formability: The Q235 base material offers good tensile and yield strength while maintaining excellent ductility. It can be easily cut, welded, drilled, and formed into various shapes without compromising its structural integrity.

Cost-Effectiveness: By offering a long service life with minimal maintenance requirements, Q235 Galvanized Steel Plate provides an outstanding return on investment, reducing the need for frequent replacements.

Aesthetic Appeal: The galvanized coating provides a clean, bright, and uniform spangled surface finish that is visually appealing for both functional and architectural applications.

Protective Coating Options: We offer a range of coating weights (e.g., Z60, Z90, Z120, Z180, Z275 as per ASTM A653) to meet specific environmental demands, from mild indoor exposures to severe outdoor conditions.
