What is ZAM

What is ZAM

High corrosion resistance | High scratch resistance | Concrete compatible | Attractive finish

ZAM coating is a blend of zinc, aluminium (6%) and magnesium (3%)
that provides far greater corrosion resistance than hot-dip galvanized coatings.

ZAM coated steel is a 21st century material developed by Nisshin Steel of Japan,
a world leader in steel making technology and a major manufacturer of coated
and stainless steel in the Asia-Pacific region.

 

ZAM coated steel advantages

+ New generation coating technology
+ Vastly improved corrosion resistance
+ Suitable for severe environments
+ Faster delivery than post-galvanized steel
+ Replaces need for higher coating weights
+ Raw edge protection
+ Concrete compatible
+ Scratch resistant
+ More economical than post-galvanized steel
+ No reduction in product performance
+ Attractive, satin matt finish

Self-healing performance of ZAM steel

Spray Salt Test for Zn-Al-Mg steel and Galvanized steel, the result shows anti-corrosion of Zn-Al-Mg steel is 4-5 times than that of galvanized ( 24hours SST is equivalently 1 year practical life in neutral environment)

Top 1 advantage for ZAM coated steel is its self-healing performance on the cutting part of profile when appearing red rust. As we know the rusting always start on the cutting part caused by processing or punching profile. However elements of Mg and Zn of Zn-Al-Mg steel will dissolve preferentially and deposit on exposed cut edges. Then stable alkaline zinc chloride is formed in the later stage of corrosion.

For demonstrate this conclusion, Solaracks spent few months to test it and the test results are consistent.

SHOUGANG profile

Shougang Group Co., Ltd., formerly Shougang Corporation is a Chinese state-owned steel company. Top 5 Zn-Mg-Al coated steel manufacturer in the globe.

There are 4 steel groups could produce hot rolled zn-al-mg coated steel beside China. SHOUGANG STEEL as the fifth in the world, also the sole manufacturer that could produce zn-al-mg steel up to 3.0mm thick in China.

SHOUGANG owns 2 production lines include hot rolled and cold rolled.

Hot rolled producing line -500,000 tons/year

Cold rolled producing line-200,000tons/year

What benefits of SOZAMC?

1. 30 years practical life

Provide 30years warranty for Zn-Al-Mg products in the C1~C4 atmospheric corrosion environment

2. 10% cost saved

At least 10% cost saved compare with hot dipped galvanized steel ,that’s large amount for large scale project.

Less procedures of hot dipped galvanizing and surface treatment will save cost and reduce pollution.

3. High strength

Solaracks supplied Zn-Al-Mg solar mounting structure is made of S350GD steel which has higher yield and tensile strength than aluminum alloy. Perform well withstand wind and snow pressure.

4. Environmental protection

There is no pollution include dust and waste gas emission during processing it.

5. Application in PV solar mounting system

Perform well withstand wind and snow pressure.
