In addition to their exceptionally high strength and better performance characteristics, galvanized pipes https://anticredit.org.ua/ocinkovannye-truby-preimushhestva-sfery-primeneniya-i-dolgovechnost/ have other differences from their uncoated counterparts: they have electrochemical protection and (due to the coating) are on average 2-3% heavier. That is why they are shipped not by actual, but by theoretical weight in full compliance with the manufacturer's certificates. The main disadvantage of steel is its poor resistance to corrosion. To prevent rust from corroding steel, the metal is coated with a layer of zinc.
