We pulled 3,800 linear feet of W6 I-beam out of our cooling tower basin and replaced it with Pultrude profiles. Eighteen months later, not a spot of corrosion. The steel we removed was 40% section loss.

The comparison PDF they sent showed us $312,000 in 20-year lifecycle savings on a single bridge deck replacement. DOT approved it on the first submittal — the third-party cert data sealed it.

Procurement approved it in one meeting. The 6-month steel replacement cycle was costing us $80k per shutdown. We haven't touched the FRP grating in 4 years.
