Wholesale of Aluzinc Coil: Price of High-Weathering Aluzinc Coil and Application Cases in Photovoltaic Mounting Systems

In the modern industrial materials sector, aluzinc coil has become a key material in industries such as construction, automotive, and new energy due to its excellent corrosion resistance and high weathering properties. Particularly with the rapid development of the photovoltaic industry, the widespread application of aluzinc coil in photovoltaic mounting systems has attracted significant attention. 

This article explores the wholesale price, high-weathering characteristics, and application cases of aluzinc coil in photovoltaic mounting systems, focusing on the selection and procurement considerations for hot-dip aluzinc coils and aluzinc steel coils, providing practical reference for industry users.

Characteristics of Aluzinc Coil and Factors Influencing Wholesale Price

Aluzinc coil is a composite material coated with an aluminum-zinc alloy on a steel substrate through a hot-dip process, combining the weathering resistance of aluminum and the sacrificial anode protection of zinc. It offers excellent corrosion and high-temperature oxidation resistance. High-weathering aluzinc coil is further optimized for harsh environments, such as coastal areas or industrial pollution zones. 

The wholesale price is influenced by various factors, including raw material costs (aluminum-zinc alloy ratio), coil thickness and width, market supply and demand, and procurement volume. Typically, products with higher aluminum-zinc content (e.g., 55% aluminum, 43.4% zinc, and 1.6% silicon) command higher prices but offer longer service life, reducing long-term maintenance costs. During procurement, it is essential to compare multiple suppliers, balance price and quality, and ensure compliance with international standards (e.g., ASTM A792).

Application Cases and Advantages of Aluzinc Coil in Photovoltaic Mounting Systems

In photovoltaic power generation systems, mounting systems are exposed to outdoor conditions for extended periods, enduring rain, wind, UV radiation, and temperature fluctuations. Thus, the materials require high weathering resistance and strength. Aluzinc coil (especially hot-dip aluzinc coil) is the preferred material for photovoltaic mounting systems due to its high corrosion resistance and cost-effectiveness. 

For example, a large-scale photovoltaic power plant project used aluzinc steel coils for its mounting system. After hot-dip treatment (aluminum-zinc coating weight of 150-165g/m²), the system performed excellently in desert high-temperature and high-humidity coastal environments, with a service life of over 25 years without frequent maintenance. During application, the mounting design must match the mechanical properties of the coil (e.g., yield strength ≥550MPa) and enhance protection through surface treatment (e.g., painting or passivation). 

In wholesale procurement, high-weathering aluzinc coils specifically designed for the photovoltaic industry should be prioritized to ensure system reliability and power generation efficiency.

Procurement and Application Considerations

When wholesaling aluzinc coils, focus on material certification, supplier reputation, and application suitability. 

First, select suppliers with ISO certification and request material reports and weathering test data (e.g., salt spray tests exceeding 1,000 hours). 

Second, determine parameters based on the application scenario (e.g., photovoltaic mounting systems, building roof panels): hot-dip aluzinc coils are more suitable for heavily corrosive environments, while ordinary aluzinc steel coils can be used for general purposes. During price negotiations, consider bulk discounts but avoid compromising quality. 

Additionally, monitor market trends (e.g., zinc price fluctuations) to optimize procurement timing. In photovoltaic projects, collaborate with design teams to calculate load and weathering requirements, avoiding failures due to insufficient thickness or coating. Regularly inspect the mounting system to extend its service life.

In summary, aluzinc coil plays a vital role in fields such as photovoltaic mounting systems due to its high weathering properties and cost-effectiveness. Through scientific selection, strict procurement, and rational application, companies can enhance project durability and reduce overall costs. With the development of green energy, the demand for high-weathering aluzinc coils will continue to grow, warranting industry attention.
