PRODUCT INTRODUCTION
★ Zn-Al-Mg coating steel has better corrosion resistance. The increase of Al and Mg content in a certain range makes the corrosion resistance of Zn-Al-Mg coating steel sheet increase several times higher than that of GI.
★ With low friction coefficient and stable friction characteristics, it is very favorable for punching. It can reduce the amount of wear on the coating, thereby reducing the part's pulling defects.
★ The Zn-Al-Mg coating steel has good welding performance. The addition of magnesium can reduce the spatter of the weld attachment in the laser welding process and improve the welding performance.
SPECIFICATIONS
★ 1 Good paint adhesion
★ 2 Good cutting edge corrosion
★ 3 Good scratch resistance
★ 4 Good rub resistance
★ 5 Good peel resistance
★ 6 Good spot welding performance
★ 7 Good laser welding performance
★ 8 Good bonding properties
Compared with the traditional hot-dip galvanized square rectangular tube, the corrosion resistance and self-healing performance of zinc aluminum magnesium square tube are greatly improved, helping to extend the service life of the bracket, and the advantages of zinc aluminum magnesium square tube used in photovoltaic brackets are very significant. Zinc aluminum magnesium square tube zinc aluminum magnesium plating is a ternary alloy coating whose main component is zinc, in addition to the content of aluminum and magnesium between 1.5~8% (of which the magnesium content is not less than 0.2%).

TEST
Corrosion resistance
From left to right:
Scratch corrosion, plane corrosion, cut edge corrosion
photos of Z140 and ZM100 after 10 cyclic CCT
Exposure on the island of Miyakojima after 5 years
SST Standard: GB/T 10125
The coating weight on both sides: 275 g/m2
Conclusion:Corrosion resistance of Zn-Al-Mg coating steel is significantly better than that GI
CCT Standard: JIS SO M609
★ 2 hours neutral salt spray
★ 4 hours dry:60ºC,RH 30%
★ 2 hours wetting: 50ºC, RH95%
Cut edge SST standard: GB/T 10125
Test sample: Coating weight(double side) is 275g/m2
Conclusion:Cutting edge corrosion resistance of Zn-Mg-Al coating is better than that of GI.
After SST or CCT, a dense colloidal corrosion product was covered at the edge of Zn-Mg-Al alloy coating. The main component wasZn5 (OH)8Cl2 ·H2O. The corrosion product was proved to be very stable and not easy to decompose.
Surface hardness
Zn-Al-Mg coating steel have higher surface hardness.
The initial dynamic friction coefficient of Zn-Al-Mg coating steel is same as that of GI, but changes little with the increase of friction times. It is favorable for deformation.
Scratch resistance
Less and smaller friction particles of Zn-Al-Mg coating steel. It can be significantly reducing tool wear, downtime for cleaning, defects in parts.
MESCO advantages of Zn-Al-Mg coating steel
MESCO Steel Co. has six galvanizing production lines, which can produce cold-base and hot-base galvanizing products. The coatings include pure zinc, zinc-aluminium-magnesium and aluminium-silicon. The products cover most kinds of buildings, household appliances and automobiles.
MESCO Steel Co. Ltd. produces galvanized aluminium and magnesium products in 3 # galvanized line. The production line adopts DCC full radiation tube vertical annealing furnace technology of Danieli Company, Italy. The galvanized pot uses two pots and three pots to produce flower-free galvanized and galvanized aluminium and magnesium products respectively.
