Galvanized Sheet Metal vs Stainless Steel – What’s the Difference

Galvanized Sheet Metal vs Stainless Steel

When it comes to metalworking, there are a lot of materials that you can use for different projects. Two of the most common metals used for metalworking are galvanized sheet metal and stainless steel. But what’s the difference between them? Let’s break it down.

Galvanized Sheet Metal

Galvanized sheet metal is made from steel coated with a zinc layer to protect against corrosion. This type of sheet metal is commonly used for outdoor applications such as roofing and siding because it is extremely durable and resistant to rusting. It is also relatively inexpensive compared to other metals, making it a popular choice for many projects.

Galvanized sheet metal is not as strong as stainless steel, so it may not be the best choice if you need something that can withstand a lot of wear and tear. Additionally, galvanized sheet metal can corrode over time if exposed to moisture or chemicals, making it less durable than other types of metals.

Stainless Steel

Stainless steel is a type of steel alloyed with chromium, nickel, and molybdenum for increased strength and durability. It is often used in industrial construction due to its resistance to corrosion from acids, alkalis, and saltwater. Stainless steel also does not easily rust or tarnish like regular steel when exposed to moisture or salt water. This makes it an ideal material for applications where durability and longevity are important factors. Additionally, stainless steel is very easy to clean, which makes it great for food preparation surfaces. However, this type of metal tends to be more expensive than other types, such as galvanized sheet metal so keep that in mind when deciding which material to use in your project.

Difference Between Galvanized Sheet Metal and Stainless Steel

Stainless steel vs galvanized steel strength

The debate between stainless steel and galvanized steel regarding strength is ongoing, as there are pros and cons to both. Stainless steel is resistant to various elements such as water, heat, dust, and corrosion, making it suitable for outdoors. Galvanized steel is coated with a thin layer of zinc which gives it some corrosion resistance but does not guarantee the same level of protection as stainless steel. In terms of strength however, galvanized steel tends to be stronger since its coating makes it harder than stainless steel. Ultimately, the decision on which type of material to use should be based on what properties are needed in order to obtain the desired result as they both have unique advantages depending on the project or application.


One of the primary differences between galvanized sheet metal and stainless steel is the cost. Galvanized sheet metal is typically less expensive than stainless steel, as it does not contain chromium. However, stainless steel may be more expensive in the long run as it is more resistant to corrosion and requires less maintenance.


Another difference between galvanized sheet metal and stainless steel is its appearance. Due to the zinc coating, the galvanised sheet metal has a dull, matte finish. Stainless steel, on the other hand, has a shiny, polished finish.


Finally, galvanized sheet metal and stainless steel differ in terms of durability. Galvanized sheet metal is more susceptible to corrosion than stainless steel, but it is also easier to repair if it does become damaged. Stainless steel is more resistant to corrosion and damage, but it can be more challenging to repair if it becomes damaged.


When deciding between galvanized sheet metal vs stainless steel, there are several things you should consider, including cost, durability, strength, maintenance requirements, and application environment. If you need something that will last a long time without needing much maintenance, then stainless steel might be the right choice for you but if cost is an issue, then galvanized sheet metal may be better suited for your project needs. Ultimately the decision rests on what kind of project you are working on, as each material has its advantages depending on the application environment, so make sure you research before choosing one over the other!
