Porous cable trays strictly follow industry manufacturing standards, and their structural parameters, material properties, and construction specifications comply with general engineering construction specifications, which can meet the acceptance requirements of various bidding and infrastructure projects. The standardized mass production process of the product effectively controls production costs, and compared to high-end special cable trays, it has a good cost performance ratio. At the same time, its performance can meet the needs of most conventional wiring engineering. Good heat dissipation and anti-corrosion performance reduce the probability of cable failures, reduce the maintenance costs of later line maintenance and replacement, and lower long-term operating expenses for engineering projects. The modular accessory system has high universality, convenient accessory procurement, simple replacement and maintenance, and overall adaptability to large-scale engineering construction and small and medium-sized renovation projects. It is a basic building material product that balances practicality and economy in various cable laying projects.
