ZAM Steel – Features, Advantages, Prices

ZAM steel is a type of steel suitable for high environmental requirements. Its coating is composed of magnesium, aluminum, and zinc elements, so its performance is superior to galvanized steel. Of course, the price is slightly higher. Wanzhi Steel specializes in the production of ZAM steel coils and steel plates, multiple production lines, timely delivery of bulk orders, galvanized steel coils, and galvalume steel coils exported to dozens of countries, welcome to visit our factory online. The following summarizes comprehensive information about ZAM, continue reading.

Key Features of ZAM

• Longer service life than other coated products.
• Cut edge rust protection – the hallmark feature of ZAM.
• Thinner coating yet more protection – ecologically friendly.
• Excellent in severe environments – especially coastal and agricultural.
• Eliminates the need for post-dip (batch) galvanizing.
• Superior formability due to coating characteristics.
• Cost savings through longer service life and reduced maintenance.
• Bridges the product gap between heavily coated Galvanized Steel  and costly   stainless steel.

What is the composition of Zam steel?

Its substrate is steel, so its composition is steel + coating composition. The following are the detailed parameters of the coating composition:

• Zinc (Zn): As the main component of the coating, it usually accounts for 90-96 % of the total coating and provides the main corrosion protection.
• Aluminum (Al): Generally accounts for 1-8%of the total coating, which helps to improve the adhesion of the coating and further enhance corrosion resistance.
• Magnesium (Mg): The content in the coating is usually 1-4%, which can significantly improve corrosion resistance in harsh environments.

What is ZAM-coated steel?

Its full name is Zinc Aluminum Magnesium Steel, which is zinc-aluminum-magnesium alloy steel. According to the definition of European standard EN10346-2015, zinc-aluminum-magnesium coating is a ternary alloy coating with zinc as the main component and aluminum and magnesium content between 1.5-8% (magnesium content is not less than 0.2%). Therefore, it is an alloy-coated steel made of zinc (Zn), aluminum (Al), and magnesium (Mg) elements. This steel is widely used in many fields due to its excellent performance.

What is the difference between hot dip and ZAM?

The ZAM-coated steel has a low coefficient of friction and stable friction characteristics. It can be cut and used directly. Traditional hot dip galvanizing requires galvanizing, refinishing and surface treatment, which is a tedious process.

How thick is the ZAM coating?

Thickness: 3.2mm; coating weight: 150/150 g/m2; post-treatment: chromate 50 mg/m2.) The color tone and the speed at which the tone changes vary depending on the exposure environment (region, installation location, orientation, etc.

Colored ZAM steel sheet can also be coated with colored paint. The coating thickness at this time is determined by your application. Wanzhi Steel supports RAL color card color selection and produces colored ZAM steel.

Advantages of Wanzhi ZAM Steel

WanZhi Steel is one of the few suppliers in China that can produce 430g/m2 ZAM coating. Wanzhi Steel has 2000 tons of ZAM steel in stock with a thickness of 0.6-2.5mm… so delivery time is very fast

Features of Wanzhi ZAM Steel

1. Wanzhi ZAM coating has good corrosion resistance. Within a certain range, with the increase of Al and Mg content, the corrosion resistance of Zn-Al-Mg coated steel plate is several times higher than that of GI.

2. Low friction coefficient and stable friction characteristics, which are very beneficial for stamping. It can reduce the wear of the coating and thus reduce the tensile defects of parts.

3. It has good welding performance. The addition of magnesium can reduce the spatter of weld attachments during laser welding and improve welding performance.
