本规范涵盖用于排水管和地下排水管的波纹钢管（CSP）制造中使用的钢板。钢板通过热浸工艺在连续生产线上涂有商用纯铝（称为2型），并且仅在一个涂层质量中生产。该材料以扁平线圈和切割长度提供，并以切割长度提供波纹。

This specification covers steel sheet used in the fabrication of corrugated steel pipe (CSP) used for drainage pipe and underdrains. The steel sheet is coated with commercially pure aluminum (referred to as Type 2) on continuous lines by the hot-dip process, and is produced in one coating mass only. The material is furnished flat in coils and cut lengths, and corrugated in cut lengths.
