Black Steel finish

The black steel finish is created in a process in manufacturing of this pipe fitting after casting. Its name comes from the scaly, dark-colored iron oxide coating on its surface. It’s used in applications that don’t require galvanized steel. This pipe is not used for drinking water but black steel pipe’s strength makes it ideal for transporting water and gas in rural and urban areas and for conduits that protect electrical wiring and for delivering high pressure steam and air. The oil and petroleum industries use black steel pipe for moving large quantities of oil through remote areas. It has an oiled finish that protects it from corrosion for some time when used in furniture. A new coating of Linseed oil should be applied to items of furniture once manufactured to create a rubbed iron appearance. You may choose to apply Linseed oil to your finished project to maintain a dark cast iron lustre.
