My roomate, who is a general contractor,just told me about the new increases in steel prices.Concrete reinforcing steel(rebar),doubled in one day.Structural steel (I beams and heavy gauge steel)will double in price over the next thirty days.Lightweight steel(framing studs used mostly in comercial apps.),30%this month,30% next month and 40% the month after that,effectively doubling the price over the next 3 months.Even scrap steel is moving up smartly though I dont have numbers for that.I see this as another confirmation that base metal prices will continue to move higher in the near and mid term.
