Hello, I work in a apparel manufacturing warehouse and i'm planning to upgrade the Jacket Hanger Racks to a rotatable conveyor. So I want to insert new Steel Pipes for hanging the Jackets which will rotate. So, the length of the pipe is 370 cms / 12' 2", and the weight it will be holding is 200kgs / 440 lbs and the pipe will not be fixed but it will be attached at the ends on a chain conveyor. So, I want to know what composition or type of steel should I use so that the pipe doesn't bend or break with the load. Thank you.
