Products Description
Hot-dip Galvanized Solar Ground Mount
Hot-dip Galvanized Solar Ground Mount is a ground-mounted system designed to support PV modules. Its key feature is the use of hot-dip galvanized (HDG) steel, which enhances corrosion resistance and durability, making it suitable for various outdoor environments. Hot-dip Galvanized Solar Ground Mount has become the mainstream choice for ground-mounted photovoltaic power plants due to its high corrosion resistance, strong load-bearing capacity, and low maintenance costs, making it particularly suitable for harsh environments or projects requiring a long service life. Longsun Green places a strong emphasis on the quality of the galvanizing process, structural design compatibility, and localized after-sales service.

Key Features
1. Hot-dip galvanizing (HDG) corrosion protection treatment
Process: Steel is immersed in molten zinc (approximately 450°C) to form a dense zinc-iron alloy layer, providing long-term rust protection.
✅ Corrosion resistance: Suitable for high humidity, saline-alkali soil, and acid rain areas (such as coastal areas and farmland).
✅Long lifespan: The galvanized layer can last over 25 years, far exceeding ordinary painted or electroplated steel.
✅Maintenance-free: No need for regular repainting, reducing long-term costs.
2. Structural Design
Material: Uses Q235 or S355 high-strength steel, with a galvanized thickness of ≥65μm (compliant with ASTM A123 standards).
Types:
Fixed-angle type: Low cost, suitable for large-scale photovoltaic power plants.
Product Advantages
Green Energy Serves a Better Life.
Ultimate Corrosion Resistance
Made from HDG steel with a corrosion-resistant coating (salt spray test ≥ 20 years, ASTM B117 standard), suitable for extreme environments (coastal, high salt and alkali, industrial pollution areas), with a service life of over 25 years.
Comparative Advantages:
The galvanized coating extends corrosion resistance by 2-3 times compared to ordinary coatings, reducing the risk of structural failure due to corrosion.
Heavy-Duty Engineering
Ultra-high load capacity:
Supports double-sided modules + extra-large photovoltaic panels, with wind pressure resistance of 150 mph (approximately 67 m/s) and snow load resistance of 5500 Pa.
Specifically designed for harsh terrains (deserts, mountains) and extreme climates (blizzards, hurricanes).
Structural Safety:
Compliant with IEC, ASCE 7 international standards, and global building codes, with third-party load-bearing certification.
Lower LCOE
Quick Installation:
Pre-assembled modular design + quick adjustment method, improving installation efficiency by 40% and reducing labor costs.
No regular anti-corrosion maintenance required, avoiding power generation losses due to shutdowns for inspections.
Long-Term Benefits:
15-year limited warranty ensures rack stability throughout the power plant's lifecycle, maximizing return on investment (ROI).
For Project Developers & EPCs
Scalable Deployment:
Supports rapid implementation of projects ranging from 100kW to 100MW+, with standardized specifications to simplify procurement complexity.
Applications
Large-scale ground-mounted power plants (projects over 1 MW)
Commercial and industrial rooftops (requires concrete ballast foundation)
Agricultural-photovoltaic/aquaculture-photovoltaic integration (moisture-resistant, corrosion-resistant)
High wind speed/snow load regions (high structural strength, customizable wind-resistant design available)

Common Problem
Will galvanized brackets rust?
High-quality HDG brackets will not rust under normal conditions for 30 years, but if the galvanized coating is damaged (e.g., after cutting without re-galvanizing), local repairs are required.
Are they suitable for saline-alkali soil?
Yes, galvanized corrosion resistance far exceeds that of aluminum alloy, but it is recommended to choose reinforced types with a zinc layer ≥80μm.
How much higher is the cost compared to ordinary steel brackets?
Galvanized treatment increases costs by approximately 15%–20%, but extends the lifespan by more than double, making it more cost-effective in the long term.
