Steel is way stronger than plastic, so it can handle heavy loads and the pressure from stuff like big machines or lots of traffic. This toughness helps keep it from getting damaged and makes it last a long time.
Steel pipes are built to stand up to rough conditions, especially around chemicals or wastewater. While some plastics can break down over time if they touch certain things, steel can often get a special coating to help it resist erosion and rust.
Steel pipes can handle higher temperatures than most plastics, which can get soft or bend if they get too hot. This is really important for drainage systems that might deal with hot stuff.
When steel pipes are buried, they keep their shape better than plastic pipes, which can get squished or collapse under heavy loads or shifting soil. That’s why steel is a reliable choice for drainage systems that need to stay stable for a long time.
Plus, steel is fire-resistant, so it’s a safer pick in places where there’s a risk of fire.
