GB/T 4171-2000 in English

《GB/T 4171-2000高耐候结构钢》由TC183（全国钢标准化技术委员会）归口，主管部门为中国钢铁工业协会。
本标准规定了高耐候性结构钢的定义、尺寸、外形、技术要求、试验方法、验收规则及包装、标志、质量证明书等。本标准适用于耐大气腐蚀的热轧、冷轧钢板、钢带和型钢。车辆、集装箱、建筑、塔架和其他结构件用的产品通常在交货状态下使用，可制作螺栓连接、铆接和焊接的结构件。

Scope

This standard specifies the definition, size, shape, technical requirements, test methods, acceptance rules, packaging, signs, quality certificates, etc. of high weather resistance structural steel. This standard applies to hot-rolled and cold-rolled steel sheets, strips and section steels resistant to atmospheric corrosion. Products for vehicles, containers, buildings, towers and other structural parts are usually used in the delivered condition, making bolted, riveted and welded structural parts. The thickness of steel used as welded structural parts should generally not be greater than 16mm.
