re: Football Ops Weight Room Extension construction-that's some rusty steel!

Weathered steel. The rust patina prevents further corrosion. Has something like 100 year corrosion resistance. I misspoke about the galvanization. It's been a while since I've had to us the knowledge.

I doubt that's a "Weathering Steel" alloy. That type is typically used in exposed applications where future corrosion control preventive maintenance (prepping and applying protective coatings) is very expensive and access is challenging - bridges, stadiums, etc.

I think we're just looking at structural members that weren't shop primed and have been exposed to LA's rain and humidity.
