Dura-Bar: An Alternative to Castings

Dura-Bar continuous cast iron is a high quality alternative to castings. With Dura-Bar, there is no sand or carbides, so there are no defects like those typically found in castings and Dura-Bar comes with a unique Zero Defect Guarantee.. Dura-Bar's material consistency stems from the continuous casting process used to produce it. Continuous casting involves pulling bars through a graphite die
