About Metal Tubing

Low-Carbon Steel Round Tubes
Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength, such as frames, supports, and conduit. This steel is manufactured to ASTM, SAE, or EN standards for quality and performance.
Heat treatable tubes can be surface hardened.
