Steel has been a trusted plumbing supply material for many decades and continues to be used in many plumbing applications. This black schedule 40 pipe conforms to ASTM plumbing code and is constructed of high-quality steel that will support most common residential and light-commercial projects. Another feature of this pipe is the ability for this pipe to be used in decorative projects. This pipe will withstand many common light-weight bearing projects and just needs to be cleaned and sealed to prevent rusting or erosion from taking place.
