PART 1: How to bend tubing. Structural steel tube is a great compromise between strength and weight. Tube is built to be used in structural applications and to contain pressure. Pipe is built to transport fluids and gases. Don't confuse the two. We don't want to use pipe unless we are building plumbing or exhaust on our 4x4s. We want to use structural tubing for 4x4 hard parts. Welded seam, drawn over mandrel (DOM), and chromoly tube are all great options to make bumpers, rollcages, shock hoops, frame crossmembers, roof racks, tire carriers, and more. By adding bends to said tubing, it becomes much more versatile. Heck, you can almost build an entire 4x4 rig out of tube if you know what you're doing.
