Precast Shapes are manufactured using castable. The castable is poured into a form, allowed to dry, and then dried out in a furnace for quick heat-up upon installation of your application. Precast shapes can be manufactured using virtually any castable, allowing you to select the proper refractory for your application. We offer various precast shape applications, some including but not limited to; nozzles, burner blocks, troughs, piers, lintels, sills, jambs, deltas, arches, etc. Contact Carpenter Brothers to help assist with your application.
