SURFACE TREATED METAL PLATE AND METHOD OF PRODUCUNG IT

摘要

A coated metal plate is obtained by extruding thermoplastic resin (3) from a die (4) directly onto a preheated metal plate (1). The surface of the plate can optionally be chemically pretreated, and an adhesive layer may be provided between the metal and the thermoplastic layer, for example by co-extruding it with the thermoplastic resin. The coated metal has superior anti-corrosion properties and appearance, and ca can be used in many different fields.
