Wide Range

So many things can be made from steel, and there are more than 100 grades of it. There are five major groups of stainless steel: austenitic, ferritic, martensitic, duplex, and precipitation-hardening. These are categories of metallurgical structures. The hollow tubes can be round, square, or rectangular. They can be welded or seamless. All of these can be used in things like construction, industrial applications, the medical industry, and to manufacture automobiles. You can even make a bike with steel tubing.

In construction, you often see supports and steel tubing used to make scaffolding and stairs. Metal scaffolding is commonly used because it requires no nuts or bolts and is quick and easy to put together. The tubing is strong and can hold workers and heavy equipment.
