Ensure product quality and transportation
ZAM steel is also called zinc-aluminum-magnesium coated steel. The biggest feature of zinc-aluminum-magnesium coated steel is its self-repairing ability and strong corrosion resistance.
Aluminum-magnesium-zinc steel is a new type of steel with corrosion resistance 10-20 times that of galvanized steel. Its rust resistance can reach the standard of stainless steel, but its price is lower than that of stainless steel. Wanzhi Steel has a galvanized aluminum-magnesium production line with an annual output of 200,000 tons, which can deliver quickly.

Application of zam steel
- Architecture: perforated plates, metal facades, roofs, keel ceilings, cable trays, building panels, etc.
- Agriculture and livestock: greenhouse steel structures, steel structure accessories, greenhouses, feeding equipment, chicken houses, pig pens, arched buildings, granaries, silos, etc.
- Transportation and power industry: industrial HVAC, cooling towers, solar brackets, school bus decks, road sign posts, guardrail facades, coastal environments, cable trays, power transmission and distribution high and low voltage switch cabinets, box-type substation exteriors, etc.
Features of zam steel
- Superb corrosion resistance: 5-10 times more corrosion-resistant than ordinary galvanized steel, with self-repairing protection for cutting edges ((because of magnesium).
- Long service life: due to the super corrosion resistance of zam steel, its service life is more sustainable.
- Excellent machinability: zam steel is wear-resistant and scratch-resistant, and can adapt to various processing.
- Reduce costs: zam steel’s anti-rust ability can reach the standard of stainless steel, but the price is 40% cheaper than stainless steel.
- Self-repair ability: zam steel has unique characteristics and self-repair ability. When the coating is scratched or cut, the magnesium in zam steel can form an oxide film on the cross section, separating the coating from the external environment to prevent corrosion.
The role of each element in the zam steel coating
First, let’s introduce the main components of the coating in the zinc-aluminum-magnesium steel. The content of zinc 80%-90%, aluminum 5%-11%, magnesium 1%-3% and a small amount of silicon.
The main function of zinc is to prevent steel from rusting.
The role of magnesium is to improve corrosion resistance, because adding magnesium to the coating can reduce the surface tension of the coating and reduce the occurrence of leakage plating.
The role of aluminum can enhance the corrosion resistance and heat resistance of steel.
The small amount of silicon in zam steel is mainly to inhibit the reaction between aluminum and iron.
The performance of galvanized steel and zam steel in salt spray corrosion experiments is shown in the figure below:
ZAM Steel vs GI Steel vs GL Steel
| Comparison items | ZAM steel | GI steel | GL steel |
| Coating composition | Zn (80%-90%), aluminum (5%-11%), magnesium (1%-3%), forming Zn-Al-Zn₂Mg ternary eutectic structure | Pure zinc coating, Zn≥99% | 55% aluminum (Al), 43.4% zinc (Zn), 1.6% silicon (Si) |
| Corrosion resistance | Extremely strong, stronger than gl, with self-repair function, adaptable to high salt and high humidity environment | Medium, relies on zinc layer sacrificial anode protection, easy to corrode in harsh environment. | Good, 2-6 times that of GI steel, resistant to high temperature corrosion (stable below 315°C) |
| Processing performance | Excellent (180° bending without cracks) | Excellent (good ductility) | Good (aluminum layer is prone to cracking) |
| Classic applications | Strong corrosion environment such as coastal buildings, chemical plants, high humidity areas, photovoltaic brackets, marine engineering, etc. | General environment such as ordinary buildings (roofs, walls), furniture, pipes, etc. | Chemical equipment, high temperature furnaces, chimneys, oven parts, etc., where corrosion resistance and high temperature resistance are required |
| Price | Highest, due to complex process and superior performance | Minimum, mature production process, high cost performance | Medium, between ZAM steel and GI steel |
