The types of porous Cable Trays on the market are clearly classified according to structural styles, sheet materials, punching processes, and usage scenarios. Different types have different performance advantages and applicable working conditions, which can accurately match the differentiated needs of various strong and weak electrical wiring and intelligent engineering. This facilitates construction parties to select materials according to their needs and carry out precise construction, avoiding engineering problems caused by selection deviations.

According to the overall structural form, Porous cable trays are mainly divided into two categories: covered closed and open. The covered porous bridge is equipped with a dedicated sealing cover plate, which can effectively prevent dust and debris from falling while retaining the advantages of bottom punching heat dissipation and moisture resistance. It also takes into account heat dissipation and dust protection, making it suitable for scenarios such as office buildings, computer rooms, and precision electrical control equipment workshops that require high wiring cleanliness. Open type porous bridge without cover plate obstruction, with full ventilation and heat dissipation efficiency, making installation, wiring, and maintenance more convenient. It is commonly used in general scenarios such as industrial workshops and external wiring on assembly lines.

Divided by material and craftsmanship, the mainstream is divided into four core types. Carbon steel electrostatic spraying porous bridge, with a uniform and dense surface plastic layer, anti oxidation, anti dust accumulation, beautiful and uniform color, is the most commonly used basic category of indoor fixtures; The electroplating galvanized porous bridge has a simple process, stable basic rust prevention performance, and is suitable for conventional short-term wiring projects, with strong economic practicality; The hot-dip galvanized porous bridge is subjected to high-temperature zinc immersion deep treatment, and the zinc layer penetrates firmly, resistant to salt spray and weathering. It is specially suitable for outdoor outdoor, tunnel, and coastal humid areas engineering; Stainless steel porous bridge is corrosion-resistant, acid and alkali resistant, and not easy to rust, suitable for special corrosion conditions such as chemical, pharmaceutical, and food clean workshops.

In addition, there are also customized special categories, including widened porous cable trays, raised protective porous cable trays, large-span extended porous cable trays, and thickened heavy-duty porous cable trays. They are specially customized and produced for special construction scenarios such as dense cables, large-span high-altitude laying, and heavy-duty cable carrying. The categories are complete, covering both conventional and special engineering wiring needs.
