Have 100 ft. long sheets of 1/4 to 3/8 possibly up to 1/2 inch thick galvanized steel material to cut. Is there some sort of rolling sheer with cutter wheels or nibler that is made to put on a 30,000 to 70,000 lbs machine that could cut this into 40 ft. lengths for semi trailer to haul?
How wide ?
A plasma cutter would sail through that stuff.
That was my thinking, far cheaper as well.
Plasma cutter and a powered respirator for cutting galvanized metal. Zinc poisoning would be a real concern without some protection.
Number of and Dimensions of sheets would help determine how much you invest in this project
