Zinc-iron alloy has high hardness. However, it has the following disadvantages:
The disadvantage of important life is that the corrosion resistance is very poor, and generally some bad corrosive environment will rust. At present, there is little circulation in the market, and few enterprises specialize in producing such products, and there is a shortage of in stock in the market.
The price is relatively high, and the manufacturing cost is higher than that of galvanized sheet. At the same time, the anti-corrosion effect is worse than 304 stainless steel.
Aluminized zinc can only be used as substrate, and can only be applied to painting door. The appearance must be painted, otherwise it is corrosion-resistant, antibacterial and antioxidant.
Zinc-iron alloy gate is relatively heavy, as the Gate often switch is not light enough.
Installation and transportation costs are relatively high. Future maintenance costs are also high.
Zinc Alloy is easy to deform compared with stainless steel.
