The metal merchants (that supply mainly big stuff for the mining industry) and where I buy my stuff from all use bandsaws. Not that I buy anything big, most of the stuff I buy is from their scrap bin, Stainless, Bisalloy plate, ally etc.
Their bandsaw setups are large (typically 30" deep throats). They bundle up 6x6" tube into packs of 16 and use upright power feed saws to cut trough the entire pack.
The speciality steel merchants I go to all use power feed bandsaws even to cut single pieces. They do have a cold saw in a corner covered in dust and I have never see it in use. A smaller scale supplier of steel for local fabricators, and my mate that runs a steel fabrication business use cold saws. Every now and then my ute calls me and says they're having a clean out and I come before a certain date it save him sending it for scrap. Last year I got bunch of stainless angle which has come in really handy. I made a small log frame out of some of the SS angle to hold logs shorter than the distance between the bunks on the BS mill.
I have a $100 metal cutting bandsaw that I bought 10 years ago and it was probably 20 years old when I bought it. Its slow BUT it's quiet, no sparks and can be left to cut and turn itself off while I do something else. Using a bimetal blade it cuts stainless really nicely.
I do have a small home made abrasive table saw that uses a 5" thin kerf blade that I use to cut small still or rip longer pieces. It has a mitre slide and is driven by a 1HP variable speed 3P grinder motor. The mitre and table are made of stainless and most of the sparks are caught by dust extraction and the baked bean can under the table.
