About Metal Tubing

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. These tubes are often fabricated into parts that don’t require high strength, such as frames, supports, and raceways. To increase their wear resistance, you can surface harden them with heat treating. These tubes are manufactured to ASTM or EN standards for quality and performance.

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.

Seamless tubes are stronger than welded tubes.

High-Polish Stainless Steel Tubing for Food, Beverage, and Dairy

The interior and exterior are polished to a high-luster finish to resist particle buildup and allow for easy cleaning. Tubing is welded with a smoothed weld bead on the inside.

304/304L stainless steel tubing has very good corrosion resistance. Tubing that meets DIN 11850 and DIN EN 10357 complies with international standards for food industry stainless steel tubing.

Note: Ra measures the smoothness of the tubing; the lower the Ra value, the smoother and more polished the surface.
