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。
4 l' F M1 m' Q! ^接触过一些资料，比如什么时候不适用耐候钢4 G& f; { N' v3 h- ]3 z6 E3 {
• 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。
% `7 o- O# ]8 u7 ^9 r• 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。4 J* {" g& g9 y# ]
• If the steel is in direct contact with timber decking; timber retains moisture and may have been treated with corrosive preservatives.

• 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.+ X& r2 {/ Q0 {
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。0 f9 ~0 @9 Q; x- s6 {% e
