ABSTRACT:
A galvanized steel sheet has a coating layer of protective material applied to its surface where the steel sheet has been roughened prior to application of the protective material. The improvement is characterized by the roughened steel surface having a pattern which ensures desired consistent quantity of coating during application of the protective material. The pattern provided on the sheet surface has a multitude of depressions defined by a plurality of ridges. The upper surfaces of the ridges defining a plane for each side of the steel sheet, where the ridges have a surface area less than 1/4 the nominal surface area of the sheet side. Each depression has a depth defined by a continuous side wall extending into the plane of the sheet side. The side wall slopes downwardly of the plane at an angle greater than 45.degree.. The multitude of depressions on the sheet side picks up a sufficient quantity of coating material to provide the desired consistent quantity of coating on the sheet surface when solidified and adhered thereto. This improvement in the pattern on the sheet side can increase the amount of protective material provided by 2 to 3 times what can be realized with existing roughened surfaces of steel sheet prepared for galvanizing.
