During the installation and maintenance of rooftop photovoltaic systems, it is crucial to choose the right walkway material.Steel plate mesh walkways and ordinary steel grating walkways are two common choices.This article will analyze in detail the differences between the two walkways and why steel plate mesh walkways are more common in actual applications.
-- The difference between steel plate mesh walkways and ordinary steel grating walkways
1. Structure and material:
- Steel plate mesh walkways: Usually made of high-strength steel, the surface is treated with anti-corrosion, and has good weather resistance and corrosion resistance. Its structural design makes it light and easy to install and carry.
- Ordinary steel grating walkways: Generally welded from flat steel or round steel, the surface is also treated with anti-corrosion. Its structure is relatively simple, but it is heavy and requires more support structures to bear the load.
2. Carrying capacity:
- Steel plate mesh walkways: Due to its special grid structure, it can evenly disperse the load and provide good carrying capacity. In addition, its light weight also helps to reduce the pressure on the roof.
- *Ordinary steel grating walkway: Although it also has a certain bearing capacity, due to its heavy weight, it may cause additional burden on the roof, especially in the case of a large span.
3. Air permeability and drainage performance:
- Steel plate mesh walkway: It has good air permeability and drainage performance, which can effectively prevent water accumulation and moisture from eroding the roof structure. This is very important for keeping the roof dry and extending its service life.
- Ordinary steel grating walkway: Although it also has certain air permeability and drainage performance, due to its relatively closed structure, it may not be as effective as the steel plate mesh walkway.
4. Maintenance and replacement costs:
- Steel plate mesh walkway: Due to its simple structure and light weight, maintenance and replacement are relatively easy. If it is partially damaged, it can be repaired quickly, reducing long-term operating costs.
- Ordinary steel grating walkway: Once damaged, it may need to be replaced as a whole, which increases the difficulty and cost of maintenance.
5. Safety:
- Steel plate mesh walkway: The surface is usually anti-slip treated, which can maintain good grip even in wet conditions, improving walking safety.
- Ordinary steel grating walkway: Although there are anti-slip measures, its surface is relatively smooth and may pose a safety hazard in rainy days or other slippery conditions.
-- Why are steel plate mesh walkways more widely used?
1. Reduce roof load: The self-weight of the steel plate mesh walkway is light, which reduces the extra weight burden and the impact on the roof structure for roofs with photovoltaic panels installed.
2. Easy to install and maintain: The structural design of the steel plate mesh walkway makes the installation process simpler and faster, and maintenance is also more convenient. This is especially important for photovoltaic systems that require frequent inspection and maintenance.
3. Improve safety: The surface of the steel plate mesh walkway has been specially treated with good anti-slip properties, ensuring the safety of workers when working on the roof.
4. Economical and practical: Although the initial investment may be slightly higher than that of ordinary steel grating walkways, in the long run, steel plate mesh walkways are more economical due to their lower maintenance costs and longer service life.
5. Strong adaptability: The steel plate mesh walkway can be customized according to different roof shapes and sizes, adapt to various complex roof environments, and meet the needs of different projects.
In summary, steel plate walkways are more widely used in rooftop photovoltaic areas due to their advantages of lightness, durability, good air permeability, easy installation and maintenance, etc. Of course, the specific type of walkway to be selected depends on the actual project needs and budget.
