Secondary steel is new and has never been used, but for a variety of reasons it cannot be used in the application it was originally manufactured for. Even though it’s not suitable for its primary purpose, there are thousands of secondary uses for it! The reasons for pipe and tubing to be classified as secondary are many. It may be too long, too short, too big, too thick, too thin or too small. It may just have a cosmetic flaw. The best part is the cost. New secondary steel is available for a fraction of the original price.
