ERW black steel pipes are widely used in fencing, scaffolding, line pipes, and other engineering fields. According to the end-needs, these pipes come in a variety of quality, wall thicknesses, sizes, and finishes.

ERW steel pipe is made by pulling a ribbon of steel through a series of rollers and forming it into a tube that is then fused with an electric charge. Steel that has not been galvanized is used to make black steel pipe. The scaly, dark-colored iron oxide layer on its surface gives it its name. ERW Steel Pipe is available in a number of sizes and lengths, ranging from 3/8 inch OD to 10 inch OD. Surface finishes in bare and coated formats are available, and ERW steel pipe processing can be done on-site to customer specifications.
