Provided is a coated steel sheet having excellent press formability. The coated steel sheet includes a base steel sheet and, on at least one side of the base steel sheet, a film containing organic resin and wax. The organic resin is at least one selected from the group consisting of acrylic resins, epoxy resins, urethane resins, phenolic resins, vinyl acetate resins, and polyester resins. The wax is polyolefin wax having a melting point that is 100 C. or more and 145 C. or less and an average particle size that is 3.0 m or less. The proportion of the wax in the film is 5 mass % or more and 70 mass % or less. Coating weight variation is 0.300 or less. Coating weight .sub.W of the film is 0.3 g/m.sup.2 or more.

A composition and method for reducing the coefficient of friction and required pulling force of a wire or cable are provided. A composition of aqueous emulsion is provided that is environmentally friendly, halogen free and solvent free. The composition is compatible with various types of insulating materials and may be applied after the wire or cable is cooled and also by spraying or submerging the wire or cable in a bath. The composition contains lubricating agents that provide lower coefficient of friction for wire or cable installation and continuous wire or cable surface lubrication thereafter.
