Will steel cost more? most likely, at least on the front end. But will it cost more over the next 10, 25, 50, years when it comes to making major and expensive repairs?
A lot of that **** is below at right at safe building steel. If theres one area in this buy today, replace in 6 months, because problems start showing up, that shouldn't be that way....buildings and bridges.

Tony Dickens, project director of the joint venture, said quality issues were identified shortly after the steel arrived in February and strength tests were conducted.
The batch of below-strength steel forced a design rethink for two bridges along the section.
"The solution we have implemented includes a redesign of the steel tube piles, which are now being used as reinforced concrete piles for two of the bridges due to time constraints," Dickens said in a statement.
The roading contractor has since asked Steel & Tube to find replacement steel piles for two other bridges.
Dickens said the NZ Transport Agency was alerted to concerns about the steel's quality "as soon as it was discovered".
The roading contractor will cover the cost of buying the replacement steel.
Kaye Clark, NZ Transport Agency's Hamilton highways manager, said New Zealand takes only a small fraction of Chinese steel, with the product sourced from different manufacturing plants.
It was "very unlikely" that one batch of steel would supply more than one project in New Zealand.
"In the event that did happen, the stringent quality assurance process which the transport agency requires its contractors to follow, would identify the problem, as it has in this case," Clark said.
Steel & Tube said the batch of steel was subject to independent testing, including a pre-export inspection by SGS - a global inspection and verification company.
Asked if test results could have been altered, Clark said that was something for the supplier and the relevant regulatory authorities to determine.
"The most important thing is that there will be no financial impact on the taxpayer," Clark said.
