Pre-Zinc pipes, also known as GI pipes, are a crucial component in various industries and construction projects. These pipes are made from galvanized steel sheets that undergo slitting to achieve the required strip sizes. The steel strips are then rolled into a pipe shape, and the seams are welded in a straight line. In this guide, we’ll explore the features, benefits, and possible applications of Pre-Zinc pipes.
