ISMT is one of the largest and most diversified manufacturers of specialized seamless tubes in the world, producing tubes varying in outside diameter from 1/4 inches to 11 inches (6mm to 273mm). Our tubes are used in a variety of applications such as the manufacturing of auto-components, bearing races, OCTG products, drill rods, boilers, heat-exchangers, etc.

Using finished tubes, we manufacture a number of value-added products such as cold-rolled and machined rings for bearings, cages for constant velocity joints (CV cages), swaged and machined axles for trucks, steering columns, gear blanks, and ready-to-hone tubes for hydraulic cylinders.
