Ladder Cable trays are building materials for cable laying, which are suitable for the laying of cable bridges with relatively large diameters. The ladder cable tray is a new type of cable tray that adopts a new design concept and acts on the maintenance and management of industrial equipment cables. It adopts imported automation technology to produce products with high consistency, high precision and beautiful appearance. It is suitable for metallurgical, petroleum, chemical, vehicle, ship, hydraulic machinery and other equipment manufacturing and equipment automation production lines. The process of the ladder cable tray is machined, and the scope of application is: the mechanical strength of the ladder cable tray is high, the rigidity of the metal bridge and the tough polymer cable bridge of the glass steel bridge are both combined, and It is easy to install, corrosion resistant and weather resistant. Polymer cable trays combined by the characteristics of polymer materials and plastic additives with additional properties are more suitable for use in highly corrosive environments, large spans, and heavy loads. Cable laying in indoor and outdoor areas of petrochemical, textile metallurgy, power communication and other enterprises.
    Ladder cable tray has large bearing capacity (6 m spacing without support), convenient construction, large number of tube labor costs, green environmental protection, recycling and fire retardant (flaming point 240° to 300) °), corrosion resistance, aging resistance, anti-static, shielding, etc., the service life can reach 50 years.
    Ladder cable trays are widely used in chemical, metallurgy, petroleum, pharmaceutical, transportation, real estate, communications, industrial and mining, and other fields. The main body of the bridge adopts a solid section structure and is cold rolled. It is a 2mm plate with a thickness of Zn, and is repeatedly pressed into a plus type to add bridge capacity and resistance to phase bending to prevent acid or deformation of the bridge. The external polymer anti-flame retardant material must be processed by mature and reliable technology, and the surface layer has high surface layer and impact; the inner layer is micro-foamed closed-cell structure to reduce the weight of the bridge itself and increase the strength of the bridge. It should only be resistant to acid, salt, and other media.
