Ultra-Strength Carbon Steel (AHSS) Round Tubes
- Yield Strength: 100,000 psi
- Hardness: Rockwell C26 (Hard)
- Heat Treatable: No
The same steel used in automobile bodies, this AHSS (advanced high-strength steel) allows you to fabricate high-strength parts using thinner material than you could with other types of steel. It is formable, weldable, and more economical than alloy steel. It's sometimes called HSLA (high-strength low-alloy) steel.

Easy-to-Weld A572 Alloy Steel Sheets and Bars
- Yield Strength: 50,000 psi
- Hardness: Rockwell B75 (Medium)
- Maximum Hardness After Heat Treatment: Not Rated
- Specifications Met: ASTM A572
Combining strength with weldability and formability, A572 alloy steel is an economical choice for structural components, such as channels, beams, and framing. It has a low carbon content, making it easy to weld with a variety of welding methods. Stronger than other low-carbon steels, such as A36 steel, it handles heavy loads without fracturing. Tested using ASTM A572, these sheets and bars are safe for jobs that require a yield strength of 50,000 psi or less.

Weather-Resistant Easy-to-Weld A588 Alloy Steel
- Yield Strength: 50,000 psi
- Hardness: Not Rated
- Heat Treatable: Yes
- Fabrication: Hot Rolled
- Specifications Met: See table
When it’s exposed to the elements, this steel forms a thin shell of rust that shields the interior from corrosion. It’s also known as weathering steel. Low carbon content makes it very weldable. Since you don’t need to paint this steel to prevent corrosion, it requires less maintenance than other types of steel—it’s commonly used in bridges, buildings, and fencing. It’s comparable to Corten steel. With a yield strength of 50,000 psi, this steel is stronger than A36 and other low-carbon steels. It can also be surface hardened with heat treating for added wear resistance. This steel meets ASTM standards for corrosion resistance and strength.
