What is the minimum flange width for tracks used in structural steel framing?

  1. 1 inch

  2. 1 1/4 inches

  3. 1 1/2 inches

  4. 2 inches

The correct answer is: 1 1/4 inches

The minimum flange width for tracks used in structural steel framing is 1 1/4 inches. This dimension is established to ensure adequate strength and stability in supporting loads, as well as to facilitate proper connection with other structural elements. A flange that is too narrow may not provide the necessary support or may complicate the connection process, increasing the risk of structural failures. The choice of 1 1/4 inches aligns with industry standards and best practices, which require a balance between structural integrity and material usage. A flange width greater than this may not be necessary for certain applications, while anything less could undermine the effectiveness of the framing system. This standard helps ensure that all components are correctly sized for their intended load-bearing roles in construction.
