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。. P2 x- o* F0 Z6 y; b
接触过一些资料，比如什么时候不适用耐候钢4 W( T" y" ]# ~8 ^- i! {
• 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。/ y j* X/ d3 a' d
• 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。4 M# Q! I- p% C. i: a
• 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.& c% }+ I0 L3 M& o7 D
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。/ T( Z; K, O% X X; h" e
• If the location has high rainfall and humidity or is constantly wet. This situation is rare in Texas.* X: k. z2 v, a# A
如果该桥址有高雨量和湿度，或者是长久潮湿。
