Hot-Dipped Galvanized Steel Pipe for Solar Ground Mounting Systems
Hot-dipped galvanized (HDG) steel pipes are a popular choice for solar ground mounting structures due to their durability, corrosion resistance, and cost-effectiveness. Here’s a breakdown of their benefits, applications, and key considerations:
1. Why Use Hot-Dipped Galvanized Steel Pipes for Solar Mounting?
Superior Corrosion Resistance: The zinc coating (typically 50-100µm) protects against rust, making it ideal for outdoor and harsh environments.
Long Lifespan: HDG steel can last 25-50 years with minimal maintenance, matching solar panel lifespans.
High Strength & Durability: Supports heavy solar arrays and withstands wind, snow, and seismic loads.
Low Maintenance: Unlike painted or untreated steel, HDG requires no regular repainting.
Cost-Effective: Lower long-term costs compared to stainless steel or aluminum alternatives.
2. Common Applications in Solar Ground Mounting
Support Posts/Piles: Vertical or angled supports driven into the ground.
Rails & Beams: Horizontal structures holding solar panels.
Bracing & Framing: Reinforcing the mounting system for stability.
Fixed-Tilt & Tracking Systems: Used in both simple fixed-angle mounts and advanced solar trackers.
3. Key Specifications for HDG Solar Mounting Pipes
Material: ASTM A53, A500 (carbon steel) or equivalent.
Galvanizing Standard: ASTM A123 (minimum coating thickness ~85µm for harsh environments).
Sizes:
Round Pipes: 2" to 6" diameter (common for posts).
Square/Rectangular Pipes: 40x40mm to 100x100mm (for rails/frames).
Wall Thickness: 2.0mm to 6.0mm (depending on load requirements).
 
Characterictics
Galvanized ERW (Electric Resistance Welded) steel square pipes are widely used in solar racking systems due to their superior strength, corrosion resistance, and cost-effectiveness. These pipes provide a stable and durable framework for mounting solar panels, ensuring long-term performance even in harsh environmental conditions.
 
Characteristics of Galvanized ERW Steel Square Pipes
High Strength & Durability – Manufactured using high-quality steel, these pipes can withstand heavy loads and extreme weather conditions.
Corrosion Resistance – The galvanized coating prevents rust and extends the lifespan of the pipes, making them ideal for outdoor applications.
Precision Engineering – ERW technology ensures uniform thickness, smooth surfaces, and tight dimensional tolerances.
Easy Installation – Square shape allows for secure bolting, welding, and assembly in solar racking structures.
Customizable Length & Thickness – Available in different sizes and thicknesses to meet specific project requirements.
