High-Performance Solar Ground Mounting Solutions
Single-post and dual-post mounting structures are the backbone of utility-scale solar farms, requiring a balance of structural integrity and cost-efficiency. Winture provides engineered ground-mounted solutions designed to withstand extreme wind and snow loads while simplifying on-site assembly.
By leveraging our integrated supply chain, we manufacture all structural components in-house using premium Zinc-Aluminum-Magnesium and Hot-Dip Galvanized (HDG) steel. Our Zn-Al-Mg-coated purlins, rafters, and bracings offer superior self-healing properties, making them the ideal choice for long-term investment in desert, coastal, or industrial environments. At Winture, we don't just supply racks; we provide the foundation for a 50-year infrastructure service life.

Solar Ground Mounting Structure Engineering and Design
WINTURE supports utility-scale solar projects with structural analysis, 3D modeling and value engineering. Using SAP2000, STAAD.Pro and Tekla Structures, our engineering team evaluates steel member sizes, connection details and structural layouts against project-specific design requirements.
Our engineering services focus on three areas:
Steel Consumption Optimization: Evaluate steel sections and material utilization to identify opportunities to reduce structural steel weight while meeting project design requirements.
Installation Efficiency: Optimize component geometry and connection details to simplify assembly and reduce on-site adjustments.
Site-Specific Design: Account for wind and snow loads, terrain conditions and foundation requirements when developing the mounting structure design.
WINTURE can identify opportunities to reduce steel consumption by 5–15%, depending on the original design, project loads and applicable structural standards.
Submit your preliminary layout, PV module specifications, site design criteria and existing drawings for an engineering review of your solar ground mounting structure project.
