Mild Steel Exhaust Tubing – Types and Benefits

Mild Steel Exhaust Tubing

Mild steel exhaust tubing is a popular choice for much automotive performance and custom exhaust projects. It’s durable, inexpensive, and has a great look. But what is mild steel exhaust tubing, exactly? Let’s dive into the different types of mild steel exhaust tubing and how it affects your project.

Mild Steel Exhaust Tubing

Mild steel exhaust tubing is made from low-carbon steel or cold-rolled steel. This type of material is strong and can withstand high temperatures. It’s also easy to shape and weld, making it a great choice for custom fabrication projects such as building an exhaust system from scratch. Plus, it’s relatively affordable compared to other metals like stainless steel or aluminum.

Types of Mild Steel Exhaust Tubing

There are two main types of mild steel exhaust tubing available – aluminized mild steel and pre-galvanized mild steel. Aluminized mild steel has a protective coating that helps resist corrosion for up to eight years in some cases. Pre-galvanized mild steel has an additional layer of zinc added to the outside surface, which gives it superior corrosion resistance over regular aluminized steel but also increases its cost slightly. Both types are suitable for use in automotive applications, with either type providing excellent durability when used correctly.

Advantages & Disadvantages Of Using Mild Steel Exhaust Tubing

The primary benefit of using mild steel exhaust tubing is its affordability compared to more expensive materials like stainless or aluminum. Additionally, it’s easier to shape than other materials, which makes it ideal for custom fabrication projects where you need precise bends or curves in the piping design. The downside is that it doesn’t have as much corrosion resistance as other metals, so you will need to take extra care when cleaning and maintaining your system over time if you choose this material for your application.


Mild steel exhaust tubing is a great option for automotive performance and custom exhaust projects due to its affordability, strength, ease of shaping and welding, and overall versatility when used properly. Whether you choose aluminized or pre-galvanized material depends on your budget and desired level of corrosion resistance, but both types offer excellent durability in most applications. As with any metalworking project, be sure to use the proper safety equipment at all times when working with any type of metal, including mild steel!
