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。' t% ]0 y& c5 h2 J% I* v' Y
接触过一些资料，比如什么时候不适用耐候钢' j' | v, g/ b
• 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。* j% K) k- w( j
• 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。: H* {, l G2 o$ |4 O: C
• 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.
