Did You Know? For offshore photovoltaic (PV) projects, operation and maintenance (O&M) teams prioritize corrosion protection even more than daily electricity revenue. But why is that?

PV projects are exposed to outdoor environments for extended periods and can be categorized into marine PV and land PV systems. Among these, marine PV faces the most severe corrosion challenges, especially in CX (Extreme Corrosion) environments, where multiple aggressive factors accelerate material degradation:

• Intense UV radiation – Speeds up material aging

• Oxygen-rich seawater exposure – Continuous oxidative corrosion

• Wet-dry cycle corrosion – Thermal cycling weakens coating stability

• Marine biofouling – Causes localized corrosion

These factors reduce the lifespan of PV structures and directly impact your investment returns. So, how can we ensure long-term protection and keep PV steel structures durable for over 25 years?

Mengneng PV Steel Structure Corrosion Protection Solution

Type 1:Anti-Corrosion Coating System for PV Trusses, Braces, and Purlins

• Primer: Graphene Zinc-Rich Primer + Graphene Low-Surface Preparation Primer

• Topcoat: Acrylic Polyurethane Coating

Why Choose Graphene Coatings?

Graphene offers exceptional corrosion resistance and outstanding barrier properties, effectively blocking moisture, oxygen, and corrosive agents. Its superior mechanical strength enhances adhesion and impact resistance, ensuring PV structures remain robust even in harsh environments.

Corrosion Protection for Tubular Steel Piles (for splash zones, immersion zones, and atmospheric zones) Splash & Immersion Zones

• Primer: Graphene Glass Flake Primer

Atmospheric Zone (with an extra protective layer) • Primer: Graphene Glass Flake Primer

• Topcoat: Acrylic Polyurethane Coating

Why Does the Atmospheric Zone Require an Additional Polyurethane Topcoat?

The atmospheric zone is mainly affected by humidity, salt spray, and UV radiation. Acrylic polyurethane coatings provide excellent UV resistance, effectively preventing chalking, cracking, and enhancing overall weather resistance, ensuring long-lasting protection.

Certified Protection for Long-Term Reliability

Mengneng's corrosion protection system complies with ISO 12944 standards and has passed a 4200-hour cyclic aging test, ensuring 25+ years of durability. This translates to lower maintenance costs and more stable investment returns.
