Magnelis S350 ZM275 Structural Steel Solar C-Shaped Channels represent a premium solution for solar panel mounting systems, offering superior corrosion protection and structural integrity. These channels are engineered from high-strength S350 grade steel, providing excellent load-bearing capabilities, and are coated with ZM275 Magnelis, an advanced metallic coating that significantly outperforms traditional hot-dip galvanization in harsh environments.

Definition

A Magnelis S350 ZM275 Structural Steel Solar C-Shaped Channel is a C-profiled structural component made from S350 grade steel, which signifies a minimum yield strength of 350 MPa, ensuring high structural performance. The steel is coated with Magnelis (ZM275), an innovative zinc-aluminum-magnesium alloy coating. The “ZM275” indicates a coating mass of 275 g/m² (total for both sides), offering exceptional and self-healing corrosion resistance, particularly in challenging atmospheric and alkaline/ammoniac environments. These channels are specifically designed for demanding solar mounting applications where extended durability and reliability are paramount.

Advantages

• Superior Corrosion Resistance: The Magnelis ZM275 coating provides significantly better corrosion protection than standard hot-dip galvanization (e.g., Z275), especially in environments with high chlorides, ammonia, or in alkaline soils. Its self-healing effect on cut edges is a key advantage.
• High Structural Strength (S350): S350 grade steel offers a higher yield strength compared to standard structural steels, allowing for more efficient designs, potentially using lighter gauges or enabling longer spans, thus optimizing material usage and potentially reducing costs.
• Longer Service Life: Due to enhanced corrosion resistance, Magnelis channels contribute to a much longer operational life of the solar mounting structure, reducing maintenance and replacement costs over the system’s lifetime.
• Self-Healing Cut Edges: The zinc-magnesium layer “creeps” over cut edges, offering active cathodic protection to areas where the base steel is exposed, a critical advantage over traditional galvanized steel.
• Reduced Zinc Run-off: Magnelis coatings typically exhibit lower zinc run-off rates into the environment compared to conventional galvanizing, making them a more environmentally friendly option.
• Versatility and Workability: Despite its strength and coating, Magnelis steel can be readily formed, punched, and bolted, similar to other coated steels, providing flexibility in fabrication.
• Cost-Effective over Lifetime: While potentially having a higher initial cost than standard galvanized steel, its extended lifespan and reduced maintenance often result in a lower total cost of ownership for solar projects.

Applications

• Large-Scale Ground-Mounted Solar Farms: Ideal for the primary and secondary support structures (purlins, rails, main beams) in utility-scale installations, particularly in coastal regions or areas with aggressive soil conditions.
• Commercial and Industrial Rooftop Systems: Used where maximum durability and resistance to corrosive industrial atmospheres are required for rooftop solar arrays.
• Solar Carports and Canopies: Provides a robust and long-lasting framework for solar carports, offering excellent protection against weather elements.
• Aggressive Environments: Particularly well-suited for installations in saline environments (near oceans), agricultural settings (ammonia exposure), or areas with high pollution and acid rain.
• Projects with Extended Warranty Requirements: Often selected for projects demanding long-term performance guarantees due to its superior corrosion resistance and durability.
