Steel rectangular tubing is a strong, resilient, tough and durable construction material option that can be used for a nearly endless amount of applications. The close tolerances, dense structure and good finishing abilities allow rectangular steel tubing to be utilized either statically or dynamically. Rectangular structural steel tubing can withstand extreme temperatures, pressures and an array of changing climate disparities, while being used in both industrial and domestic settings.

Steel Rectangular Tubing Advantages

Structurally sound rectangular steel tubing maintains many different types of benefits, which makes it a highly sought-after material for a wide range of applications. Rectangular steel tubing provides great strength-to-weight ratios, which means that less steel by weight is required to accomplish the job. Steel rectangular tubing also provides outstanding support and compression features, which allow this shape of steel to be used for a wide range of column applications. Some other beneficial qualities of rectangular steel tubing, include:
  • Increased uniform strength
  • Cost effective
  • Recyclable
  • High torsional strength
  • Fire resistant
  • Will not warp

Rectangular Steel Tubing Properties & Dimensions

ASTM A500 verified rectangular steel tubing maintains established, clearly defined seams that are not located anywhere within the curvature of the tube. This type of quality control allows for a consistently well-maintained product that is strong and can resist stress from all directions, while being able to easily connect to other structural shapes. A 10.6 radius of corners is also preserved so the corner section of the rectangular steel tubing does not exceed the set parameter of specified wall thickness.
It is worth noting that some of the structural steel items may contain the abbreviation “HSS,” which stands for Hollow Structural Section. Essentially, this means that the manufactured product is a square or rectangular steel tube that meets the structural specifications of ASTM A500 Grade B or C. If, however, you see the ASTM A500 designation on a print without a corresponding grade, please ask your engineer for additional clarification, since the minimum tensile strength of Grade C is higher than that of Grade B.
We also stock numerous Square Steel Tubing sizes, ASTM A500 Grade A within this spec is reserved for non-structural parts.
M & K Metals is a leading provider of ASTM A500 verified rectangular structural steel tubing in a wide range of dimensional sizes. Depending on your project needs, we can provide you with steel rectangular tubing that will allow you to complete your job on time and on budget. Contact us today for more information.

Rectangular Steel Tubing Applications

Since they are strong, relatively light and easy to weld, Square and Rectangular steel tubes are one of the most widely used materials for numerous types of applications.  For these reasons, these materials are used extensively in construction, manufacturing, in machine part manufacturing, and even in art. Other types of specific applications include the following:
  • Structural support
  • Trailer components
  • Sign posts
  • Athletic equipment
  • Frames
  • Racks
  • Safety & deck rails
  • And many more

Rectangular Structural Steel Tubing Material Properties

Steel is composed of mainly iron and carbon with smaller amounts of other elements that makeup the minority of the material structure. Nickel and manganese are often added to raw steel compositions to provide increased tensile strength and to promote increased stability within the iron-carbon solution. In addition, chromium increases the hardness of the steel, while the melting temperature, and vanadium also increases hardness while making it less prone to metal fatigue.
