Mild Steel ERW Black Pipes are high-quality pipes available in different grades and sizes, suitable for various applications in the construction industry. These pipes are made by using the Electric Resistance Welding (ERW) technique, which involves passing an electric current through the metal to create a strong bond. The pipes are black in color and have a smooth finish, ensuring a uniform appearance. With different thicknesses available, these pipes can be used for various purposes such as water supply, gas pipelines, and structural support. The pipes are designed to withstand high pressure and are highly durable, making them a reliable choice for construction projects.
