S235JR Galvanized steel plate is a high-quality, low-carbon structural steel plate renowned for its exceptional corrosion resistance and excellent mechanical properties. This product combines the strength and formability of S235JR grade steel with the protective benefits of a hot-dip galvanized coating, making it an ideal choice for a wide array of applications exposed to harsh environments.

Key Features & Advantages

Superior Corrosion Resistance:

The hot-dip galvanizing process coats the entire steel surface in a robust layer of zinc. This coating acts as a sacrificial barrier, providing long-lasting protection against rust, oxidation, and corrosion from moisture, humidity, and industrial atmospheres. It significantly extends the service life of structures and components.

Excellent Mechanical Properties:

As a non-alloy quality structural steel per EN 10025-2, S235JR offers good strength (with a minimum yield strength of 235 MPa) coupled with high ductility and impact resistance (at room temperature, +20°C). This ensures it can be easily fabricated, welded, punched, and formed into complex shapes without compromising its structural integrity.

Durable & Long-Lasting:

The zinc coating is metallurgically bonded to the steel substrate, making it incredibly durable and resistant to mechanical damage during handling, transport, and installation. It requires minimal maintenance, reducing long-term costs.

Aesthetic Appeal:

The galvanized coating provides a clean, bright, and spangled surface finish that is visually appealing for both structural and architectural applications. It can be used as a final finish or readily painted for additional color requirements.

Cost-Effectiveness:

By offering an optimal balance of performance, longevity, and minimal maintenance needs, S235JR galvanized steel plate provides an outstanding return on investment, outperforming many alternative materials.
