galvanized sheet(Because of the very large amounts of steel sheets required for motor-car bodies, metal cans, galvanized sheet and many other requirements, rolling mills to make sheet in bulk have been developed to a high degree of mechanization. 由于制造汽车车身、金属罐头盒、镀锌薄钢板以及其他许多必需品都需要大量的薄钢板，因此能大量生产薄板的轧机得以发展，实现了高度机械化。)
