Spray molded cable tray is a new generation of integral wiring building materials, which adopts the integral molding process combined with electrostatic spray protection layer. The structure has no splicing gaps and higher overall strength. It is widely used in office buildings, hospitals, chemical workshops, underground engineering and civil electromechanical wiring scenes, and is suitable for laying various types of strong and weak electrical cables. The compression molding process makes the bridge structure flat, evenly load-bearing, and less prone to deformation and distortion, making it more stable compared to traditional bent bridge structures. The surface electrostatic spray coating has strong adhesion, excellent acid and alkali resistance, corrosion resistance, moisture and dust resistance, and can adapt to complex working conditions such as humidity and high dust, effectively extending the service life of equipment. The product has a smooth and beautiful appearance, neat and tidy wiring, easy installation and strong adaptability, and supports multiple installation methods. The enclosed protective structure can effectively protect cables, reduce the probability of line failures, facilitate later operation and maintenance and line upgrades, and is a cost-effective anti-corrosion wiring profile in modern electromechanical engineering.
