Made from alloy steel, also known as chrome-moly steel, these tubes resist fracturing from repeated stress. They’re used for a wide range of parts, including cylinders, rollers, and frames.

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.

Polished to either a brushed or mirror-like finish, this material is often used to fabricate decorative enclosures and industrial workstations.

With a diameter that’s held to a close tolerance, this material is hardened for increased wear and abrasion resistance.
