Abstract

This specification covers the general requirements for steel sheet in coils and cut length, metallic-coated on continuous lines by the hot-dip process. This material is intended for applications requiring corrosion resistance. Hot-dip metallic coatings are available in six different types: zinc and zinc-iron alloy, lead-tin alloy, aluminum, aluminum-zinc alloy, zinc-aluminum alloy, and zinc-aluminum-magnesium alloy. Heat analysis shall be made to determine the percentage of carbon, manganese, phosphorus, sulfur, and other elements specified. Product analysis and coating analysis shall also be done. Mechanical properties shall be determined by tension tests. The following are tests for coating properties: coating weight test and coating bend test. There are two methods that shall be used for coating weight test: weigh-strip-weigh method and X-ray fluorescence method.
