Galvanized Steel Fireproof Cable Tray Manufacturer

Shandong Bolt Electrical Equipment Co., Ltd. and LONGJOY Cable Tray are leading manufacturers of galvanized steel fireproof cable trays, offering corrosion-resistant, fire-retardant, and structurally robust solutions.Key Manufacturers and Products

Shandong Bolt Electrical Equipment Co., Ltd. specializes in fireproof galvanized spray-painted cable trays, which are made entirely of steel. The trays undergo a galvanizing process to form a dense zinc layer for corrosion resistance, followed by a fire-resistant spray coating that enhances flame retardancy and visual appeal. These trays are widely used in power, telecommunications, petrochemical, and metallurgical industries. They provide high structural strength, organized cable management, and extended cable service life due to protection against abrasion and corrosion . LONGJOY Cable Tray produces fireproof channel cable tray systems using galvanized steel with a fireproof coating made from polymer synthetic resin, flame retardants, and high-temperature refractory materials. The coating expands under high temperatures to form a flexible, spongy carbonized layer, protecting the steel structure from deformation and maintaining load-bearing capacity. These trays are commonly used in fire control rooms, fire pumps, smoke fans, and automatic fire alarm systems, offering water and oil resistance, non-toxic coatings, and long service life . EAE USA manufactures heavy-duty pre-galvanized, electro-galvanized, or hot-dipped galvanized cable trays suitable for indoor and outdoor industrial environments. Their products include cable ladders and perforated trays, produced with robotic welding and roll forming for maximum structural durability. These trays are ideal for high cable density applications in offices, hospitals, and large buildings .
