Corigy Steel Checker Anti Slip Walkway For Metal Roof Solar Panel Maintenance

It is suitable for solar brackets and accessories, as well as a key component of rooftop solar installation systems. 

In the design of walkways for photovoltaic power stations, industrial plants or rooftop platforms, zinc-aluminum-magnesium (ZAM) walkways and fiberglass grid (FRP) walkways are two common choices. Although FRP walkways have certain advantages in terms of lightweight and chemical corrosion resistance, ZAM walkways perform better in terms of structural strength, durability, safety and life cycle costs.

  
1. Durability
ZAM walkways: zinc-aluminum-magnesium coated steel plates (Zn-Al-Mg) are used, and their corrosion resistance is 3-6 times that of ordinary galvanized steel. They are especially suitable for high humidity and salt spray environments (such as coastal photovoltaic power stations), and their service life can reach more than 30 years.
FRP walkways: Although acid and alkali resistant, they are prone to aging and brittleness under long-term ultraviolet (UV) irradiation. After 5-10 years, they may experience problems such as reduced strength and surface powdering, and need to be replaced regularly.
ZAM walkways are more suitable for long-term outdoor use and reduce maintenance costs.
2. Structural strength
ZAM walkway: It uses high-strength steel substrate, can withstand the rolling of heavy equipment (such as photovoltaic cleaning vehicles), and is suitable for high-load scenarios.
FRP walkway: Lightweight but low rigidity, easy to deform under long-term pressure, only suitable for pure pedestrian passages, and cannot meet the needs of mechanical passage.
ZAM walkway is suitable for industrial-grade load-bearing requirements, and FRP is limited to light load use
3. Fire safety
ZAM walkway: metal material, non-combustible, meets Class A fire protection standards, and is suitable for photovoltaic power stations and other places with strict fire protection requirements.
FRP walkway: It may soften and burn when exposed to high temperatures, and release toxic smoke, posing a safety hazard.
ZAM walkway is better than FRP in fire safety.
4. Installation and maintenance
ZAM walkway: modular design, easy installation, and almost no maintenance (no anti-corrosion coating repair).
FRP walkway: Long-term exposure to ultraviolet rays requires regular inspection of aging, and the replacement cost is high.
ZAM walkway has lower life cycle cost.
5. Environmental protection
ZAM magnesium walkway: Steel can be recycled and meets green building standards.
FRP walkway: It is a composite material, difficult to recycle, and easy to cause environmental pollution after being discarded.
ZAM walkway is more environmentally friendly

As an experience solar mounting structure manufacture, Corigy provide stable packaging to ensure that goods are not damaged during transportation.

Corigy Solar has been focusing on manufacturing and design solar mounting bracket for more than 10 years. Corigy's products have been installed and used in more than 30 countries and regions, with a total installed capacity of more than 8GW. After the construction is completed, all projects are completed by the official acceptance team, and they are currently officially put into operation.
In terms of selection, Corigy is based on the principle of highest quality. The bracket uses high-quality main materials high-grade anode aluminum Al6500-T5. The surface uses anode oxidation 12-15mic. Excellent anti-corrosive rust and anti-rust performance ensures its 30-year service life. At the same time, the characteristics of aluminum lightweight reduces the weight of the roof and make it safe and reliable. The maximum wind speed can carry 60m/s, and the snow load capacity is 1.4kn/㎡.
All bracket solutions of Corigy are calculated based on the live conditions environment. Corigy's advanced technical team conducted a force analysis of the structure of the building, combined with the layout of  the bracket and photovoltaic components to verify the various feasible bracket installation solutions to determine the most efficient, convenient, safe and reliable solution.
