ABSTRACT:
A corrosion protective sheet for adhesion to steel sheets which is made from elastomers and natural resin modified bitumen and which contains up to about 10% organic and or inorganic fibrous material. The sheet is coated on the underside with a melt adhesive and on the upper side with a bitumen resistant anti-block material which provides a solid sheet at a temperature under 90.degree. C. No separation sheets are needed and the adherence of the sheet on the steel surface to be protected is improved and the upper surface is rendered resistant to penetration.
