A992 vs A36: What’s the Difference and Which One Should You Use?

When it comes to structural steel, A992 and A36 are two of the most specified grades. Whether you’re ordering wide-flange beams or building out a structural frame, understanding the difference between A992 and A36 can save you time, cost, and headaches down the line.

Let’s break it down.

What Is A36 Steel?

A36 is the classic carbon steel. It’s been the industry standard for decades and is known for being:

• Mild and malleable

• Easy to weld, form, and machine

• Cost-effective

It’s commonly used in:

• Plates and bars

• Structural shapes in lower-load applications

• General construction and fabrication

Key Specs:

• Minimum yield strength: 36 ksi

• Minimum tensile strength: 58–80 ksi

What Is A992 Steel?

A992 is the modern standard for wide-flange structural shapes (think: W-beams, I-beams). It was developed to meet the most demanding needs of modern construction, offering:

• Higher strength and consistency

• Better weldability and ductility

• Improved resistance to cracking
