A ground-mounted U-section steel photovoltaic system with helical pile foundation and landscape (horizontal) module orientation represents a highly engineered, cost-effective solar racking solution optimized for utility-scale and commercial solar projects. This system combines the unique structural characteristics of cold-formed U-section steel profiles—including patented designs with enhanced flexibility and strength—with the installation speed and adaptability of helical screw piles, while the landscape orientation of modules maximizes wind load distribution and array stability.

High-Strength Steel Grades: Manufactured from various steel grades depending on application requirements.

• Q235B: 235MPa yield strength, economical for standard applications

• Q355B: 355MPa yield strength, enhanced load capacity

• S550MC/S550GD+ZM: 550MPa yield strength, high-strength option enabling 25% weight reduction through thinner sections.

Optimized Section Properties: U-section piles demonstrate excellent structural characteristics:

• Higher perimeter-to-weight ratio than equivalent I-beams or C-sections, providing greater surface area for soil adhesion.

• Superior strength-to-weight ratio compared to circular piling structures.

• Enhanced resistance to torsional forces through the U-shaped geometry.

Pre-Perforated Design: U-channel profiles feature precision-punched holes at standardized intervals.These pre-drilled holes:

• Enable flexible mounting and adjustment during installation

• Eliminate on-site drilling, preserving coating integrity

• Ensure precise bolt alignment and structural accuracy

• Facilitate modular assembly and future modifications
