A 21 mm galvanized pipe is a medium weight, standard galvanized tube with an outside diameter of 21 mm. It can be used for a variety of purposes, including: Handrails, Furniture projects, Threading, Lightweight frames Galvanized pipes are steel pipes that have been dipped in a protective zinc coating to prevent corrosion and rust. Galvanized piping was commonly installed in homes built before 1960. When it was invented, galvanized pipe was an alternative to lead pipe for water supply lines. Today, however, we have learned that decades of exposure to water will cause galvanized pipes to corrode and rust on the inside.

A 21mm galvanized pipe the most significant problem related to galvanized pipes is the mineral deposits that accumulate within the piping. Over time, it causes a reduction in water pressure and pollutes your home's water. And as rust and corrosion deepen, they compromise the piping system's stability and cause leaks. As old and corroded galvanized pipes age, they can release accumulated lead into your tap water. That lead can pose significant health concerns, as ingesting too much can result in lead poisoning, and its symptoms include fatigue, headaches, insomnia, nausea, constipation, abdominal pain, and reduced cognitive abilities. High doses of lead are of particular concern with children, as it can hinder their brain development and lead to lifelong health issues.

With an extra protective layer of molten zinc on the surface, galvanized steel pipes have a longer lifespan than conventional piping. This means that they can last for several years before needing to be replaced. With galvanized pipes, your pipes will last longer, which will save you money in the long run.
