Product Description

S450GD Cold Rolled Zn-Al-Mg Steel Coil Supplier

Product Introduction

Our S450GD Cold Rolled Zn-Al-Mg Steel Coil is designed for superior corrosion resistance and durability, making it ideal for a wide range of applications in construction, automotive, and industrial sectors. The Zn-Al-Mg coating, which consists of zinc, aluminum, and magnesium, provides excellent protection against corrosion and environmental damage.

Key Features

Enhanced Corrosion Resistance: The Zn-Al-Mg coating significantly improves the corrosion resistance compared to traditional galvanized steel coils, making it suitable for harsh environments.
Self-Healing Properties: The coating forms a dense protective film around the cutting surface, which helps to inhibit corrosion and extend the service life of the coils.
Longevity: Due to its strong corrosion resistance and self-healing effect, components made from Zn-Al-Mg coated steel can typically reach over 30 years of service life.
Easy to Process: The coating is dense and does not easily produce coated glass during the stamping process, making it excellent for welding, stretching, stamping, and bending.
Good Scratch Resistance: The surface coating has good scratch resistance, which can greatly avoid scratches during processing.
Weldability: The coils can be welded with reasonable processes and achieve the required strength, without affecting their use.
Lighter Weight: Zn-Al-Mg steel coils provide lighter weight, an advantage that is reflected in applications such as photovoltaic mounts.

Applications

Construction: Ideal for structural components, supports, and frames in buildings and infrastructure projects.
Automotive: Suitable for manufacturing parts that require high corrosion resistance and durability.
Industrial: Perfect for various industrial applications where long service life and reliability are crucial.

Packaging and Delivery

Packaging: Standard export packaging, ensuring safe transportation and handling. Each bare coil is securely tied with two bands through the eye of the coil and one circumferential. The contact points of these bands on the coil edge are protected with edge protectors. The coil is then properly wrapped with waterproof paper and completely metal wrapped. Wooden and iron pallets can be used or as per your requirements.
Delivery Time: 3-15 days, depending on the order quantity and destination
