Angle steel vs square tubing

When selecting steel materials for construction or fabrication, angle steel and square tubing are two common choices. Each has its own advantages in terms of cost, strength, and application. Here's a comparison to help determine which one may be better suited for your needs.

1. Is Angle Steel Cheaper Than Square Tubing?
The prices of angle steel and square tubing depend on factors such as material type, size specifications, and market demand. Generally speaking, for the same dimensions, angle steel tends to be slightly more expensive than square tubing. However, because steel prices fluctuate with market conditions, there is no fixed price gap between the two. It's best to check current pricing before making a decision, as both materials can vary significantly over time.

2. Is Angle Steel Stronger Than Square Tubing?
In terms of structural strength, angle steel generally outperforms square tubing. Angle steel comes in equal and unequal leg types and features fewer stress concentration points due to its open shape, which helps maintain strength under load. While square tubing offers benefits such as ease of manufacturing, uniform shape, and strong resistance to compression and bending, angle steel typically delivers better overall strength.

Furthermore, comparing tensile strength, angle steel ranges from approximately 200 MPa to 450 MPa, while rebar (used here as a benchmark) averages around 335 MPa. This further highlights the structural advantage of angle steel in many engineering applications.
