H-Beam iron is one of the steel products commonly used in construction such as for retaining building structures and piles. It is called H-Beam iron because it looks like the letter H. From its use, this steel product has an important role, for example in supporting iron poles.
Of course, the H-Beam iron raw material must not be made of something that is easily brittle. Because, according to its function, H-Beam iron itself is used to support construction or heavy loads. If it is not sturdy, the object or construction it is supporting may collapse. In fact, H-Beam iron is a steel block that is formed by a hot rolled process.
