Product Description
ASTM A252 Welded Galvanized Steel Pipe is a common pipe material, because this pipe has a galvanized layer, so the corrosion resistance and acid resistance of this pipe are greatly improved. However, there are differences in the processing of galvanized tubes. The main difference is the difference in the galvanizing process. Among them, hot-dip galvanized steel pipes are commonly used and advocated. Galvanized pipes are generally used to make fences, fences, guardrails, etc. Widely used in municipal engineering, roads, factories, schools, development zones, gardens, squares, communities and other places.
