Product characteristics

Zn-Al-Mg coating steel has better corrosion resistance.The increase of Al and Mg conten in a certain range makes the corrosion resistance of Zn-Al-Mg coating steel sheet increas several times higher than that of GI.

Product Test

Neutral Salt spray test

Corrosion resistance of Zn-Al-Mg coating steel is significantly better than that GI

Test method: The corrosion reduction was determined after 24 H in 5 %ammonia at 22 C.Test specimen end closure protection.:
1Test sample: Coating weight(both side) is 180 g/m

The ammonia resistance of Zn-Al-Mg alloy coating steelsheet is better thanthat of Gl

Application

                               Animal Husbandry                                       multistory parking area                                      Agricultural greenhouses

Zn-Al-Mg photovoltaic bracket has the following characteristics:

1The processing is simple. it can be directly cut, punched, and cold-formed.

2.Zn-Al-Mg can automatically repair the coating on the cutting press and profile

3. Corrosion resistance: the corrosion resistance ofZn-Al-Mgis 5-10 times that of hot-dip galvanizing
