A ground-mounted single-column (also known as single-pole or single-post) C-section steel photovoltaic system with Zinc-Aluminum-Magnesium (ZnAlMg) coating represents a highly optimized solar racking solution for utility-scale and commercial solar projects. This system combines the structural efficiency of cold-formed C-section steel profiles with next-generation metallic coating technology and a minimalist single-column support architecture, delivering exceptional durability, rapid deployment, and cost-effectiveness across diverse ground conditions

Core Structural Design: Single-Column Architecture

Minimalist Support Structure: The defining feature of this system is its single-column (single-pole) design, where each support point consists of a single vertical column rather than dual or multiple posts.This architecture significantly reduces the number of foundations required per array.

Foundation Efficiency: By utilizing a single column per support point, the system maximally reduces the number of pile foundations required compared to traditional dual-column designs.This reduction translates directly to lower installation costs, reduced material usage, and faster project completion.

Large-Span Capability: The single-column design enables wider spacing between support points, creating open areas beneath the array that can accommodate vegetation, equipment, or future site uses.

Dimensional Stability: The cold-formed C-section profiles exhibit predictable structural behavior under load, with engineered deformation limits ensuring panel flatness and long-term module safety.

Vibration and Seismic Resistance: The single-column design, combined with appropriate foundation selection, provides excellent energy dissipation characteristics during seismic events.
