A specification for a bridge to be built of high-performance weathering steel (HPS GR50/GR70W) requires an SSPC-SP 10, a profile of 3 to 5 mils, and metallizing with a final dft of 10-12 mils. What challenges, time, and costs are associated with obtaining the profile, primarily in the shop but also in the field? Are there any long-term performance issues with metallizing over weathering steel?
