Having the right metal for the job is essential. That’s why we offer the following options for our metal stock:
·Welded. Welded pipes are fabricated from cut lengths of plate, which are rolled in a rolling machine to create a cylinder with touching edges along one point of the cylinder’s circumference. The edges are welded together to create a fused, hollow pipe. Tubing, however, can be manufactured from endless coils slit to the desired width and rolled in a continuous line until touching edges meet and fuse together.
·Seamless. Seamless pipes or tubes are formed from solid cylinders, or billets. A mandrel is directed through the billet to hollow out the form. We finish seamless pipes and tubes by rolling and stretching the metal to meet the final desired specifications of the order.
·Milled and Polished. We offer both mill finishing and polishing in a variety of grit levels for a rough or smooth finish. Finer grit polishing offers higher resistance to corrosion and wear-related damage.
·Stainless Steel Grades. Our stainless steel pipe and tubing are available in many grades, including 301, 302, 304, 304L, 309, 310, 316, 316L, 321, 330, and 347.
·Tube Shapes. Depending on the grade of stainless steel selected, we supply tubing in rectangular, round, and square shapes.

Stainless steel pipes are strong, durable and have a high resistance to corrosion. This makes them the obvious choice for applications in which water and/or gases need to be transported. Their strength offers good resistance against internal and external pressure, and they are ideal for use in situations where longitudinal stresses or complicated bending are likely. They also offer good resistance to vibration and shock.
