How far can a 3 1/2 x 3 1/2 inch angle iron span for brick veneer support?

A 3 1/2 x 3 1/2 inch angle iron is commonly used in construction for providing support, particularly in applications like brick veneer. The spanning capability of an angle iron is influenced by factors such as the weight of the materials it is supporting, the load conditions, and the material properties of that angle iron.

In general, a 3 1/2 x 3 1/2 inch angle iron can adequately support a brick veneer when spanning up to 6 feet. This distance is typically determined by building codes and engineering guidelines that consider maximum unsupported spans to ensure structural integrity and safety. Brick veneer, while relatively heavy, can be adequately supported at this span, provided that it is properly anchored and other structural elements are considered.

Choosing this span ensures that the angle iron can maintain the load without experiencing undue stress or deflection, which can lead to issues like brick cracking or displacement. It's important for inspectors to verify that spans are within acceptable limits during assessments to uphold safety and building standards.
