我亲眼见的比较少，目前为止只亲眼见到一座建筑结构采用耐候钢。5 e5 U4 L f; x
接触过一些资料，比如什么时候不适用耐候钢# r+ u! E- b+ H7 W J5 o
• If the atmosphere contains concentrated corrosive industrial or chemical fumes.如果大气中富含有腐蚀性的工业或化学烟雾。1 G# B* ?% I9 H% V
• If the steel is subject to heavy salt-water spray or salt-laden fog.如果钢材暴露于浓度较大的盐水喷雾或含盐雾。

如果钢是用在使用融雪剂的道路隧道桥或立交桥之下的城市桥梁。在这种情况下，道路交通向下方桥梁喷洒导致盐积聚在钢材上。+ m1 _# O; a" ~" f# _

如果该桥址有高雨量和湿度，或者是长久潮湿。
