Galvanized Steel is a popular choice for plumbing applications due to its high durability and resistance to corrosion. It's often used in residential and commercial buildings where water pressure is high. However, it can be expensive to install and maintain, and may require periodic replating to prevent rust.
Pex (Cross-Linked Polyethylene) is a flexible and durable material that's commonly used for plumbing systems in residential areas. It's resistant to extreme temperatures and has a lower maintenance cost compared to Galvanized Steel. However, it can become brittle over time and may require periodic inspections to ensure its integrity.
Abs (Anticorrosive Steel) is another material that's often used for plumbing systems due to its resistance to corrosion and heavy-duty applications. It's more expensive than Pex but offers superior durability and strength. However, it can be heavier and more difficult to install than other materials.
