Made from 4130 alloy steel, also known as chrome-moly steel, these tubes have low carbon content for good weldability. They’re often used for building frames and supports, since their flat sides make them easier to bolt than round tubes.

4130 alloy steel has a low carbon content that provides good weldability. It's often used for gears, fasteners, and structural applications.

Made of stiff alloy steel, these I-beams are often used in construction, framing, lifting, and hoisting applications.

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.
