  While   metal tubes   can be formed into a variety of shapes, square and round tubes are two of the most common for a variety of applications.   But which shape is best when bending? Getting an answer isn't as simple as looking at the space where the tube will be installed or just considering what the tube will be used for. While shape is the obvious difference, there are some key factors to consider when deciding which tube style is best when bent and subsequently put into service.   Square tubing vs. Round: Which shape is best for bending? There are three important factors to consider when comparing square vs. round tubing. Manufacturing Force Formability Square tube Round Tube Although its shape does not lend itself to the impression of a tube, square tubing does perform better in some applications. Because of its flat surface, square tubing makes it easy to attach bolts and other objects to it. It can also be made to fit closer to nearby objects, thus redu...

  Rolling is a metal forming process that uses a series of rolls to change the shape, improve uniformity and/or enhance the mechanical properties of the material.   Rolled steel  can be divided into two types: hot rolled steel and cold rolled steel, which exhibit different characteristics that make them suitable for different applications. When selecting rolled steel materials for a project, it is important to understand the differences between the two types and how they affect their performance. Hot Rolled Steel Overview Hot rolled steel is steel that has undergone a rolling process at a temperature above its recrystallization temperature (typically 1700° F or higher). The processed material has a higher degree of formability and workability than unprocessed steel, making it easier to use in subsequent processing operations. The hot rolling process begins with a large rectangular sheet of metal called a billet. First, the billet is heated and compressed into a large roll...
