C-type steel photovoltaic mounting system for ground photovoltaic power station
C-type steel photovoltaic mounting system for ground photovoltaic power station is a structural support solution engineered for large-scale solar installations. Constructed from cold-formed C-section steel (Q355B or Q235B) with hot-dip galvanized coating (≥85μm), this system provides a stable, corrosion-resistant framework for solar panel arrays. The C-shaped profile offers superior strength-to-weight ratio, enabling long-span configurations that reduce foundation requirements. The system features pre-punched connection points for bolted assembly, eliminating on-site welding and accelerating installation. Compatible with both crystalline silicon and thin-film modules, the system accommodates tilt angles from 15° to 60° and supports wind loads up to 55m/s. Its modular design allows for rapid deployment across varied terrain conditions, making it a preferred choice for utility-scale photovoltaic projects.

FREQUENTLY ASKED QUESTIONS
★ What is the maximum span between supports for this C-type steel system?
The maximum span depends on the specific C-section size, load conditions, and site wind/snow loads. For standard configurations using 100x50x20x2.5mm C-section, spans of 3.0-4.0m are achievable with 150kg/m² loads. For heavier loads, reduce spacing or increase section size. Consult the engineering load tables for specific project conditions.
★ How does the system accommodate uneven terrain?
The system uses adjustable pile or foundation connections that allow height variations to compensate for ground slopes up to 15 degrees. This reduces the need for extensive site leveling, saving significant civil works costs. For slopes exceeding 15 degrees, custom stepped configurations are available.
★ Can this system be used with trackers or is it only for fixed-tilt applications?
This is a fixed-tilt mounting system designed for stationary PV arrays. It is not compatible with single-axis or dual-axis trackers. However, the modular design allows for easy tilt angle adjustment during installation based on site latitude and design requirements.
★ What is the corrosion protection durability of the galvanized coating?
INSTALLATION GUIDELINES
Conduct geotechnical survey to determine foundation type and embedment depth based on soil bearing capacity and frost line depth.
Use galvanized or stainless steel fasteners for all connections to maintain corrosion protection across joints.
Verify torque on all bolted connections per engineering specifications; over-tightening may deform C-section profiles.
STORAGE & MAINTENANCE
Store C-section components in a dry, ventilated area to prevent moisture condensation and potential white rust formation.
Inspect galvanized coating for damage during transport; apply zinc-rich touch-up paint to any exposed steel prior to installation.
Annual visual inspection of foundation connections and fastener torque is recommended for long-term system integrity.
