The types of trough Cable Trays on the market are finely divided, mainly based on surface treatment processes, materials, structural functions, and usage environments. Different categories have different performance, uses, and adaptation scenarios. Accurately distinguishing the types of cable trays can effectively avoid construction hazards and resource waste caused by improper material selection in engineering, and meet the differentiated needs of different electromechanical wiring, municipal engineering, and industrial construction.

According to the surface treatment process, it is currently the most commonly used classification method for engineering material selection, which mainly includes four categories. Spray painted trough type bridge is a popular universal category, with uniformly attached flame-retardant plastic powder on the surface, which has the functions of rust prevention, dust prevention, and fire prevention. The color is neat and beautiful, suitable for indoor fixtures, commercial buildings, office buildings and other conventional scenes. Galvanized trough type cable tray has a simple process and outstanding cost-effectiveness, suitable for laying ordinary lines in dry indoor environments, and is a commonly used basic category for small and medium-sized tooling projects.

Hot dip galvanized trough bridge belongs to the category of long-term anti-corrosion. After high-temperature galvanizing process, the zinc layer has strong penetration adhesion, excellent resistance to weathering, salt spray, and moisture. It is specially suitable for harsh environments such as outdoor, tunnel, and coastal areas with high humidity and salt content, and has a service life far exceeding that of ordinary galvanized bridge. In addition, stainless steel trough bridge is a high-end special category that is acid and alkali resistant, corrosion-resistant, and not easy to rust. It is suitable for special working conditions such as chemical, pharmaceutical, and food purification workshops that require extremely high cleanliness and anti-corrosion.

According to their structural functions, they can be divided into three types: ordinary sealed type, waterproof reinforced type, and reinforced heavy-duty type. Ordinary sealed type with built-in cover plate, complete basic protection, suitable for conventional light load wiring; Waterproof reinforced type with dedicated sealing strips and sealing accessories, with tight seams and no fear of water accumulation and moisture; The bottom of the reinforced heavy-duty bridge frame is equipped with reinforcing bars, which have stronger overall rigidity and higher bearing capacity, making it suitable for large-span suspended ceilings and heavy-duty cable laying scenarios. Complete categories and clear classifications, capable of fully matching various construction needs in all aspects.
