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。
" W" u7 W( S: L; M }接触过一些资料，比如什么时候不适用耐候钢
/ H( L/ ^5 u0 [2 ^) C! F/ Y• 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。
3 _0 M! t; }4 ^7 L• 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。

如果钢材直接接触木桥面，木材保有水分，并可能已被防腐剂处理。
& `. l R" _3 I• If the steel is used for a low urban-area bridge or overpass that creates a tunnel-like configuration over a road on which deicing salt is used. In this situation, road spray from traffic under the bridge causes salt to accumulate on the steel.' d R- Q' d9 M( {2 |' }
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。& K5 m' n- ]) n7 n- _. J, c* F
