ZAM steel

Aluminum-magnesium-zinc steel is a new type of steel with 10-20 times the corrosion resistance of galvanized steel. Its anti-rust ability can reach the standard of stainless steel and can adapt well to various harsh environments. Wanzhi Steel has a galvanized aluminum-magnesium production line with an annual production capacity of 20w tons, which can deliver quickly.

The role of each element in the zinc-aluminum-magnesium steel coating

First, let’s introduce the main components of the coating in the galvanized aluminum-magnesium steel. The content of zinc and magnesium is 1.5%-3%, the content of aluminum is 1.5%-11%, 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:

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

1. High-strength corrosion resistance: high corrosion resistance is achieved with less coating, which is 10-20 times that of galvanized steel.

2. Long service life: due to the super corrosion resistance of zam steel, its service life is more sustainable.

3. Excellent machinability: zam steel is wear-resistant and scratch-resistant, and can adapt to various processing.

4. Reduce costs: zam steel’s anti-rust ability can reach the standard of stainless steel, but the price is 40% cheaper than stainless steel.

5. 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.
