摘要： In connection with the manufacture of zinc hot dip galvanized or galvannealed steel strip using a high strength, high tensile steel strip containing Si, Mn or Cr as a starting steel strip, the invention provides a method for hot dip galvanizing a high tensile steel strip with minimal bare spots which can manufacture a bare spot-free steel strip of quality in an inexpensive manner while minimizing process complications and lowered productivity. The invention is achieved by subjecting a cold rolled steel strip containing at least one component of 0.1 to 2.0% of Si, 0.5 to 2.0% of Mn, and 0.1 to 2.0% of Cr and optionally further containing up to 0.2% of P, in % by weight, to recrystallization annealing in a continuous annealing line, cooling the steel strip, removing a steel component concentrated layer at the surface of the steel strip by polishing and/or pickling, subjecting the steel strip again to heat reduction at a temperature from 650.degree. C. to a recrystallization temperature and to hot dip galvanizing in a continuous galvanizing line, and optionally effecting overplating and/or alloying or effecting alloying followed by overplating.

摘要： A coated steel sheet that has excellent bending workability, press formability, film adhesiveness after processing, solvent resistance, chemical resistance, stain resistance, weather resistance, electrical conductivity, and corrosion resistance, good surface appearance, and sufficient film hardness is provided. The coated steel sheet is produced by successively forming a galvanized layer and a chemical conversion coating free from chromium on both faces of a steel sheet, and forming a monolayer film on the chemical conversion coating at one face of the steel sheet. The monolayer film contains a polyester resin cured with a cross-linker and resin particles. The resin particles have an average particle size in the range of 3 to 40 μm, a glass transition temperature in the range of 70° C. to 200° C., and hardness higher than that of the polyester resin.
