Aluminum-magnesium-zinc steel, aluminum, magnesium or other trace elements (silicon, nickel, etc.) are added to the coating. Research shows that this multi-alloy coating steel has excellent weather resistance and comprehensive performance. Currently commonly used in many fields such as automobiles, animal husbandry, construction, etc., it is very suitable to replace traditional hot-dip galvanized steel or GI panels in the field of photovoltaic support.
Material structure
Excellent weather resistance (acid resistance, alkali resistance, ammonia resistance):
Test method: CCT test (Cyclic Corrosion Test)
-One cycle of CCT test (KSR1127): salt spray for 2 hours (5%NaCl, 35°C), dry for 4 hours (25%RH, 60°C), humidify for 2 hours (95%RH 50°C)

Judgment criteria for endurance life of different materials:
The endurance life study of GI K600 by the Japan Bridge Association is 25 years. Use this data as a benchmark to predict the endurance life of other materials
Excellent section repair ability

<< Advantages
◆ Strong corrosion resistance: Relevant researches and tests show that the aluminum-magnesium-zinc steel sheet has more than 5 times the corrosion resistance of ordinary hot-dip galvanized steel (GI, HGI) under the same coating amount.
◆ Environmental protection and green: The sheet can be shipped directly after forming and processing, without hot-dip galvanizing, which is green and environmentally friendly
◆ Strong self-healing ability: Excellent self-healing ability, no need to protect the processed section of the plate, and it is not afraid of general bumps and scratches during installation, transportation and use.
◆ Lower total cost: lower overall product cost and lower post-maintenance cost based on excellent product performance
◆ Excellent appearance: uniform and smooth appearance, rich color
◆ Design optimization: With optimized design, the weight of the bracket system can be reduced by 5%~15%, without the need for post-dip galvanizing, making thin-walled complex sections possible
Runhong advantage
◆ Strong product research and development capabilities, a full range of new material products are under development
◆ Large-scale project experience, rich experience in processing aluminum-magnesium-zinc materials
◆ Mature supply chain system (in-depth cooperation with many well-known aluminum-magnesium-zinc steel plants such as POSMAC)
Runhong typical case
The 70.2MW photovoltaic power generation project in Chiayi, Taiwan is the largest single-scale photovoltaic power station in Taiwan.
The project is located in Chiayi County, Taiwan Province, with abundant solar energy resources. It faces the threat of serious seawater corrosion along the Taiwan Strait, and the ground is soft. Considering the corrosion resistance and reliability of the power station, Runhong uses aluminum-magnesium-zinc plating. Steel is used as the support material, combined with the characteristics of the material and the local geological conditions, a targeted optimization design has been carried out. Runhong aluminum-magnesium-zinc steel bracket system, with its superior corrosion resistance and environmental protection characteristics, has won the favor of customers in one fell swoop.
