Yuantai Derun: Innovating Solar Solutions with ZAM Square & Rectangular Tubes
With over two decades of specialization in square and rectangular tubing, our new Zinc-Aluminum-Magnesium (ZAM) series delivers groundbreaking advancements. Compared to traditional hot-dip galvanized counterparts, ZAM square/rectangular tubes demonstrate superior corrosion resistance and self-healing properties, significantly extending support structure service life – particularly advantageous for solar mounting systems.
Key Benefits for Photovoltaic Applications:
- Cost Efficiency
ZAM-coated materials undergo continuous galvanizing pretreatment on hot-rolled substrates, enabling direct engineering implementation post-forming. This innovation:
• Reduces component processing timelines
• Enhances project schedule control
• Eliminates hot-dip post-treatment requirements
• Minimizes management overhead and labor costs
2. Environmental Sustainability
By eliminating the hot-dip galvanizing process, ZAM products significantly reduce industrial pollution associated with traditional zinc coating methods, aligning with national green manufacturing initiatives and contributing to eco-friendly industrial practices.
3. Self-Healing Protection
ZAM materials exhibit unique corrosion resistance through autonomous repair mechanisms. When scratched or cut, the coating forms a dense protective film composed of zinc hydroxide, alkaline zinc chloride, and magnesium hydroxide. This barrier effectively isolates exposed metal substrates from corrosive elements, preventing further oxidation and ensuring long-term structural integrity.
4. Standardization & Industry Recognition
With stable material properties and precise dimensional control, ZAM tubing enables standardized photovoltaic bracket production at scale. Recognized by leading energy providers, ZAM-coated products deliver:
•Superior surface quality for seamless integration
•Unmatched corrosion resistance exceeding industry standards
•Cost-effective sustainability through reduced lifecycle maintenance
•Proven ROI across utility-scale solar installations
