ERW Welded Round Steel Tube
ERW welded round steel tube is made from SAE 1010 material, which has a 0.060" wall thickness. It can also be Cold Rolled Steel (CREW) or Hot Rolled Steel (HREW) for a thicker wall thickness. ERW tubing comes in an "as-welded" condition, which means that there may be a small amount of flash inside the tube. There are two methods of manufacturing steel tubing: mechanical tubing and ERW. The former is the simplest process, requiring only minimal downstream processing. The latter involves rolling steel at elevated temperatures to produce a more www.metalandsteel.com tube. Unlike cold-rolled tube, hot-rolled ERW tubing is less strong and covered in scale and does not have uniform dimensions. But, it is the cheapest option and the most common type. ERW is a method of manufacturing steel tubing. It involves seam and spot welding. The latter is most commonly used for manufacturing steel tubing. During the process, a steel strip is unwound from coils and side-trimmed to contro...
