A ground-mounted Zinc-Aluminum-Magnesium (ZnAlMg) coated steel agricultural PV system represents an advanced evolution in solar racking technology for agrivoltaic applications. It combines the structural strength of steel with a next-generation metallic coating that delivers superior corrosion protection, self-healing properties, and exceptional lifecycle value for demanding farm environments

Structural Performance and Mechanical Properties

• High-Strength Substrate: The steel base offers excellent yield and tensile strength, with advanced grades like S550GD+ZM achieving 550MPa strength levels. This enables thinner material gauges while maintaining structural integrity

• Lightweight Optimization: Despite being steel-based, ZnAlMg systems can achieve significant weight reduction compared to traditional galvanized steel. By utilizing high-strength grades, component thickness can be reduced—purlins to 1.8mm and columns to 2.0-2.5mm—achieving up to 12% overall weight reduction.This lowers transportation costs and simplifies handling.

• Excellent Formability: The coating maintains integrity during severe forming operations including bending, stamping, drawing, and roll-forming, allowing complex structural shapes without compromising corrosion protection

Agricultural Design Features

• Elevated Structure for Dual Land Use: Like aluminum agrivoltaic systems, ZnAlMg structures are designed with high ground clearance to accommodate farming activities, livestock grazing, and agricultural machinery operation beneath the array.

• PV + Livestock" Integration: The robust steel construction is particularly suited for livestock applications, providing durable shelters for animals while generating power above. This integrated design can increase land utilization by up to 200%.

• Open Design for Crop Growth: Systems can be configured with optimized panel spacing to control light transmission, creating appropriate microclimates for various crop types while protecting them from extreme weather
