What are the differences between galvanized and copper pipes?

Galvanized pipes and copper pipes are two of the most common types of piping used in home plumbing and construction projects. While both types of pipe have their own benefits, they also have some distinct differences that users should be aware of when selecting materials for a project.

One significant difference between galvanized and copper pipes is their durability. Galvanized pipe has a much longer lifespan than copper pipe; galvanized is made of steel that has been coated with zinc to protect against corrosion, while copper can wear away relatively quickly due to the effects of oxygen and water. Galvanized pipes are also more resistant to temperature changes, making them ideal for outdoor plumbing projects.

In terms of cost effectiveness, galvanized pipes tend to be more affordable than copper pipes. On average, galvanized pipe is about half the cost of copper pipe to purchase and install. Galvanized pipes also require less maintenance over time, as they are not prone to corrosion and do not require frequent replacements like copper pipes can.

Additionally, galvanized piping has a much higher tensile strength than copper piping, meaning that it is able to withstand greater pressures and can be used for projects with higher water pressure. Copper pipes, on the other hand, are more flexible and malleable than galvanized pipe and can fit into tighter spaces.

USA Plumbing & Heating advises that when selecting materials for a plumbing project, it's important to consider all of these factors. Galvanized pipe has its own advantages over copper, but each project may require different features or functions that should be taken into account. Ultimately, the right choice will depend on the specific application and budget.
