1. In terms of color, black pipe is black as its name suggests; while galvanized pipe is a silvery white or gray pipe, which will appear this color after being plated with zinc.
2. The materials used are also different. Black pipes are usually made of cold-rolled or hot-rolled plates; while galvanized pipes are made of cold-rolled plates that have been galvanized. Since galvanized pipes are coated with zinc on the surface, they can effectively prevent corrosion and rust, so they can be used in a wider range of applications.
Although black pipes and galvanized pipes are both pipes, the price of black pipes is relatively low, which has cost advantages; while the price of galvanized pipes is higher, compared with other similar products, they have a longer service life and a more appropriate cost.
