ZAM Steel – Features, Advantages, Prices

ZAM Steel is a high performance anti-corrosion steel, composed of Zn, Al and Mg alloy coating, typical ratio: Zn 90-95%, Al 3-6%, Mg 1-3%). Its corrosion resistance is 3-6 times that of traditional galvanized steel, and it has self-healing ability and excellent cut protection. It is suitable for harsh environments such as construction, industry, and automobiles. The service life is longer, up to more than 30 years. Wanzhi Steel specializes in the production of ZAM steel coils and steel plates, with multiple production lines, a variety of substrate options, thickness and width can be customized as required, welcome to visit our factory online, or contact us for pricing.

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.

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.

Advantages 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.

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.

Colored ZAM steel

After coating, colored ZAM steel can be achieved, which is used in various buildings and home appliances, providing superior and longer-lasting performance than color-coated galvanized steel. Wanzhi Steel has a variety of paint options, including PE, PVDF, SMP, and HDP.

Uses

Applications in various fields

• Construction industry: used for photovoltaic brackets, roofs and exterior walls, highway guardrails, etc. Its corrosion resistance can withstand harsh outdoor environments, extend the service life of buildings, and reduce maintenance costs.
• Automobile manufacturing: manufacturing automobile bodies and parts, such as wheel covers, etc. Compared with traditional galvanized steel sheets, its corrosion resistance is significantly improved, suitable for complex environments, and its high hardness and wear resistance can reduce processing wear and increase the life of parts.
• Home appliance industry: manufacturing refrigerators, air conditioners and other shells. Its corrosion resistance can ensure that home appliances can be used for a long time in a humid environment, and its excellent coating performance can meet the high requirements of home appliances for appearance.
• Power and communications: manufacturing high and low voltage switch cabinets for power transmission and distribution, communication base station shells and brackets, etc. In outdoor environments, its corrosion resistance and protective performance can ensure the long-term and stable operation of equipment.
• Agriculture and animal husbandry: manufacturing breeding greenhouses, fences and agricultural equipment shells and parts, and its corrosion resistance can adapt to humid and salt spray environments, reducing maintenance and replacement costs.
