When it comes to solar power system design, safety and durability are always top priorities for engineers and investors. One often overlooked but critical component of a well-functioning PV system is the maintenance walkway. A walkway made from ZAM (Zinc-Aluminum-Magnesium alloy coated steel) not only enhances structural integrity but also provides exceptional corrosion resistance in harsh environments.

What Is ZAM Material?

ZAM is a high-performance steel coated with a mixture of Zinc (Zn), Aluminum (Al), and Magnesium (Mg). It’s widely used in construction, transportation, energy, and now increasingly in solar projects, thanks to its superior corrosion resistance and mechanical strength.

 

1. The Role of ZAM Walkways in Solar Systems

Safe Maintenance Access

As solar arrays become denser, safe access for cleaning and inspection becomes more challenging. ZAM walkways offer a sturdy, anti-slip platform for O&M (Operations and Maintenance) personnel, reducing the risk of stepping on or damaging the PV modules.

Outstanding Corrosion Resistance

Compared to conventional galvanized steel, ZAM performs significantly better in coastal, high-humidity, and chemically aggressive environments, ensuring long-term reliability with minimal maintenance.

High Structural Strength

ZAM walkways are often designed using FRP (Fiberglass Reinforced Plastic) gratings or metal grids, offering a strong yet lightweight solution compatible with various roof types such as metal rooftops or concrete roofs.

2. Long-Term Benefits of Using ZAM Walkways

 

Feature Regular Walkway ZAM Walkway
Service Life 5–8 years Over 15 years
Corrosion Resistance Moderate Excellent
Maintenance Safety Limited High
Replacement Frequency High Very low
Total Cost of Ownership Seemingly low upfront, high long-term Higher upfront, low long-term

 

3. Application Case Study

As shown in the image above, installing ZAM walkways in rooftop PV projects allows for precise placement between module rows. This not only maintains full exposure to sunlight but also creates a neat, sturdy, and visually appealing maintenance path.

4. Conclusion

In solar O&M operations, a ZAM walkway is more than just a path — it’s a commitment to safety and quality. Choosing ZAM material is not only a sign of dedication to engineering excellence but also a show of respect for the maintenance team and long-term investment returns.

If you're looking for a high-durability, low-maintenance walkway solution for your solar system, ZAM walkways are undoubtedly a top choice worth considering.
