　　The difference between fire-resistant bridge and flame-retardant bridge

　　Fire resistance refers to the ability of cable trays to maintain their basic functional performance during a fire.

　　Flame retardant refers to the ability of cable trays to suppress the spread of fire during a fire.

　　Flame retardant cable trays are divided into internal flame retardant, external flame retardant, and fully flame retardant types. Internal flame retardant cable tray is a type of tray or cable tray that is coated with flame-retardant materials or embedded with flame-retardant boards on the inner surface. It is commonly used for flame-retardant partitions, which means that when a cable catches fire, the flame-retardant section can limit the flame extension length of the cable. External flame-retardant bridge is coated with a layer of flame-retardant material on its outer surface to prevent external flames from damaging the mechanical strength of the steel bridge. The fully flame-retardant bridge is coated with flame-retardant materials or embedded with flame-retardant boards on both the inner and outer surfaces, which can protect the mechanical strength of the steel bridge and limit the flame extension length of the cable.
