Abstract: There is disclosed a method for producing aluminum coated steel comprising cleaning the surface of a steel substrate by grid- or shot-blasting or by pickling followed by rinsing with water and thermal spraying with aluminum thereon in a thickness ranging from 30 to 300 microns while heating said surface sufficiently to maintain it at a temperature ranging from about 100.degree. to 500.degree.C.The aluminum coated steel may be thereafter be treated by heating it at a temperature ranging from 150.degree. to 600.degree.C for 3 minutes to 24 hours after it has been cold-rolled to a reduction of area from 5 to 80% or after it has been hot-rolled at a temperature ranging from 150.degree. to 600.degree.C.
