Why choose Galfan Gabion Box for 10% zinc-aluminum alloy wire
The galvanized aluminum alloy Gabion Box, also known as the Galfan Gabion Box, is woven from 10%/5% aluminum-zinc alloy low-carbon steel wire. It is assembled into cages and filled with stone, which is mainly used for various hydraulic projects.
The following is the price-effective photo of zinc-aluminum alloy wire and galvanized steel wire:
Anti-corrosion function: The corrosion resistance of galvanized -10% aluminum alloy steel wire is about 2.5--3 times that of galvanized steel wire.
Air oxidation: The galvanized steel wire changes with time, the appearance gradually turns gray due to oxidation; the galvanized -10% aluminum alloy steel wire changes with time, and the appearance gradually turns black due to oxidation. The difference is that the oxidation of the surface of the galvanized steel wire will reduce the life of the Galfan Gabion Box, while the oxidation of the zinc-aluminum wire will add the life of the Galfan Gabion Box.
Price: The price of zinc-aluminum alloy wire is higher than that of galvanized steel wire.
Why would you think of using galvanized 10% aluminum alloy steel wire instead of galvanized 20% aluminum alloy steel wire and galvanized 30% aluminum alloy steel wire?
Specifically, an experiment was conducted on the relationship between aluminum content and corrosion amount in the coating. The experimental results are as follows:
It can be seen from the experimental results that the amount of corrosion in the coating is 10%, and the amount of corrosion is 5 g/m 2 /year. When the aluminum content continues to rise, the amount of corrosion increases, and until the aluminum content reaches 40%, it reaches 5g/m2/year. It can be concluded that hot-plating of 10% aluminum-zinc alloy steel wire is most suitable in terms of corrosion resistance and economical point of view.
The cost control is within a certain range, and the 10% aluminum-zinc alloy wire has the best corrosion resistance and the longest service life.
