Ron Ron Ron Posted July 20, 2022 Share Posted July 20, 2022 One of the regular drone flyers who post videos of HS2 progress on YouTube, goes by the name of "The Boy". His latest video, posted today, follows the route from Greatworth to Chipping Warden. The "green tunnel" being built on the old airfield, can be seen at the very end of the 10 minute long video. . 2 1 1 Link to post Share on other sites More sharing options...

Rusting metal is the current, in vogue design choice. There's plenty of it resulting from all the new steelwork put in place on the M27 as part of the recently completed "Smart Motorway" (Yuk!) works. Personally, I think it looks lazy, unfinished and awful. . 1 2 Link to post Share on other sites More sharing options...

We had to plan for the new, pedestrian overbridge across Stratford Station, in time for the 2012 Games, amidst all of the shiny new station bits, shiny new stadia and office/shopping blocks. When we first saw it, we all wondered why they had not, at least, primed it before erection..... I think it is still "in vogue", merely because it is cheaper than painting, and re-painting. 2 Link to post Share on other sites More sharing options...

Supposedly rusty steel doesn't rust......... So. Why are they painting the Forth Bridge? The Ordsall Chord bridges over Liverpool Road Station throat & the Ring Road in Manchester are 'Plain Rust' finish. https://goo.gl/maps/siANzyX6whpUgNXx9 https://goo.gl/maps/hfWUK9pSEkDHohi67 Edited July 20, 2022 by melmerby 1 1 Link to post Share on other sites More sharing options...
Mike Storey Posted July 20, 2022 Author Share Posted July 20, 2022 19 minutes ago, melmerby said: Supposedly rusty steel doesn't rust......... So. Why are they painting the Forth Bridge? Er, yes it does! Mild steel, and other steels usually (or previously) used for structural works, continuously degrade when rusting, unless regularly protected by painting or similar. Corten Steel (or its more recent variants) used as the preferred "weathering steel" for many bridges and other structures, does not, due to additives, mainly phosphorus, which means its tarnishing surface never affects the layers below. However, Corten Steel is between 55% and 70% more expensive per tonne than Mild steel, and perhaps 40% more expensive than stainless. But then you have to add the costs of prepping, painting, and later, multiple re-painting other steels. Hence Corten steel's whole life costs are perceived as relatively lower. 5 3 Link to post Share on other sites More sharing options...
RMweb Premium jamie92208 Posted July 21, 2022 RMweb Premium Share Posted July 21, 2022 They built a big set of student flats in Leeds clad in Corten steel. Nice and shiny when first erected. It was fascinsting to watch it rust over. The ladt areas to go were under the balconies. Jamie 2 Link to post Share on other sites More sharing options...

If you are referring to the fire in one of the Chilterns tunnels, then that was a few months ago and it shouldn't have had any impact on the latest rate of progress. In any case, the last report on Dorothy (Long Itchington tunnel) was 17 days ago, with only 96 metres left to go, I can imagine slowing down or pausing for the final few dozen or so metres, but 17 days is quite a long time to complete that short distance. Maybe they've gone off course and are now heading for Cornwall? 🙄 😇 . 1 1 2 Link to post Share on other sites More sharing options...

Those bridges for the Ordsall Chord were 'rusty' when installed. I think it depends on when it is fabricated. The building in Leeds was a new build and the Corten steel was cladding. I suspect that such items as the Ordsall bridge were fabricated offsite and rusted prior to installation. I would imagine that the same will happen with the HS2 bridges. Unfortunately my architect friend who could have told me is no longer with us. Jamie 1 1 Link to post Share on other sites More sharing options...
RMweb Premium Siberian Snooper Posted July 22, 2022 RMweb Premium Share Posted July 22, 2022 We replaced diesel generator exhausts on type 22s with Corten, the plates were "rusty" when they arrived, when they were ready for welding, those areas were ground back to "shiny" and once welded were left to go "rusty" again. 3 Link to post Share on other sites More sharing options...
