coating service


Hard facing material is widely applied in industries such as mining, oil & gas, aerospace, pulp, and agriculture. By deploying a thin metal overlay on the wear part surface, the life extends and thus saves cost than purchasing new parts for replacement. Typically the coating could be deployed on the surface of valve, pipeline, steel plate, sleeve, bearing, roll, and other wear parts.
