column in lamiera

[Cadinpiedi]

Good morning, I need a tip. I can't find the keyword that in an internet search I get back information about those folded sheet metal columns that typically support phone repeaters. I tried with columns, pliers in folded sheet, but nothing. It seems to me that once it also produced the damine, but I find nothing.
thanks in advance

Thank you!
I also arrived at this moment by crossing looking tenaris dalmine and arrived at italpress.it and cimolai.
