304 Zn-al Mg Steel Coil

304 Zn-Al-Mg Steel Coil Supplier

Product Introduction

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

Product Details:

The process flow of zinc-aluminum-magnesium coils includes the following steps: 

surface treatment, coating, curing and testing.

First, the surface of the zinc-aluminum-magnesium alloy coil is cleaned, degreased and pickled to ensure the adhesion between the coating and the substrate and surface smoothness. Afterwards, rolling coating, spraying and other methods are used to apply the coating evenly on the surface of the coil. In addition, during the curing process, the coating is baked and dried at a temperature of 110-150 °C to ensure the firmness and durability of the coating. Finally, the coated coil is inspected to ensure the quality of the product.

The advantages of zinc-aluminum-magnesium coils:

1. The anti-rust performance of zinc-aluminum-magnesium coils is 15 times that of ordinary galvanized coils, and has super anti-rust performance that exceeds stainless steel standards.

2. The various properties of zinc-aluminum-magnesium coils meet stainless steel standards, but the price of zinc-aluminum-magnesium coils is far lower than that of equivalent stainless steel materials, and the price-performance ratio is very high.

3. Zinc-aluminum-magnesium coils are widely used in construction, animal husbandry, communications, automobiles, roads, photovoltaic brackets, industrial refrigeration, etc. They have a wide range of uses and flexible uses.

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.
