Experiments show that its resistance to corrosion is 3 times of that of a traditional pure zinc coating above, and thus has attracted wide attention, and now the traditional pure zinc for developed countries in Europe and the United States with a 5% to 10% aluminum zinc alloy cage (gabion) substitution layer of stone cage net cage. Use of aluminum zinc alloy steel wire woven mesh rectangle cage. Its service life in about 70-80 years is three times the ordinary galvanized layer of steel wire.
