What is ERW Steel Tube?

ERW, or Electric Resistance Welded steel tubes, are a type of steel tubing manufactured through a specific welding process. These tubes are created by cold-forming a flat steel coil into a cylindrical shape and then welding the edges together using high-frequency electric resistance. This method ensures that the resulting tube has a strong and uniform weld seam, making it suitable for various engineering and construction applications.
