Under the same specification, flame retardant cable tray is 2.2 times more expensive than steel cable tray, its service life is more than 5 times that of steel cable tray, and its weight is 30% heavier than steel cable tray. Its service life is more than three times that of steel cable tray, and its weight is basically the same as that of steel cable tray.
