Melted zinc-aluminum alloy coating processing | Surface treatment resistant to drug damage and salt damage
Melted zinc-aluminum alloy coating
Approximately six times the lifespan of conventional plating. High corrosion-resistant aluminum alloy plating that is strong against chemical and salt damage.
Melted zinc-aluminum alloy plating is a surface treatment process that applies an alloy coating consisting mainly of zinc, with 5% aluminum and 1% magnesium, after the standard hot-dip galvanizing. Compared to standard hot-dip galvanizing, it offers approximately six times the service life and is ideal for long-term use in harsh corrosive environments such as hot spring areas, coastal regions, and roads that use de-icing agents. Even if the plating film is damaged, it has self-repairing properties that make it difficult for red rust to occur, and its high film hardness makes it resistant to scratches, allowing it to maintain a beautiful appearance for a long time. It can be applied to steel materials and various steel products.

Applications/Examples of results
[Applications] Steel materials for roads and port facilities in coastal and shoreline areas / Road materials for snowy cold regions using de-icing agents / Drainage materials for hot spring areas and facilities handling chemical products / Materials near bridges and tunnels in environments with severe salt damage and corrosion / Products for public facilities requiring long-term maintenance-free solutions.
Detailed information
-
After the hot-dip galvanizing treatment, an alloy coating is applied by adding aluminum and magnesium to the main component, zinc. *The color is an illustrative image for explanation.
-
The color tone of plating has a silvery-white luster immediately after plating, which gradually turns into a matte gray over time.
-
Sulfur Dioxide Test A test to investigate corrosion resistance in an environment assumed to be affected by sulfur dioxide gas and sulfurous gas from industrial areas and hot springs. Hot-dip galvanized: Red rust appears after 250 to 300 hours. Hot-dip galvanized aluminum alloy: More than 400 hours.
-
Salt spray test Normal hot-dip galvanized coating: Red rust occurs after 500 to 1,000 hours Hot-dip galvanized aluminum alloy coating: No red rust occurs even after 5,000 hours.
-
The test results of the cone spray indicate that the service life is approximately six times longer than that of standard hot-dip galvanized products.
