It's going to vary widely, depending on how much fabrication is involved.
At the low end for us would be wide flange bridge girders, with connection plates and rolled channel diaphragms. Those would probably be around $4000 a US Ton. Typical tonnage would be around 40.
At the high end would be our roadside dynamic message sign structures, with lots of small fabricated parts, small angles welded together, expanded metal panels, u-bolts, etc. I'd estimate one of those at around $16,000 per US Ton in today's market. Those are about 6 tons each.
