How to Choose the Right Metal for Your Outdoor Enclosure

How to Choose the Right Metal for Your Outdoor Enclosure
3 min read

When you’re building an outdoor sheet metal enclosure, you have many options when it comes to materials. It can be hard to decide which option is best for your needs, so understanding the differences between metals and their benefits will help you make an informed decision about which metal is right for your project.


Aluminum is lightweight and malleable, making it a good material choice for larger outdoor enclosures such as carports or boat docks. Aluminum won’t rust like other metals and it requires minimal maintenance, making it a great option if you don’t want to worry about keeping up with regular repairs. This metal also reflects light very well so it can help keep your enclosure cool in hot weather. Additionally, aluminum is easily recycled but it may not be as durable as other sheet metals products.


Steel is one of the most popular materials used by metal enclosure manufacturers because of its strength and durability. This metal won’t corrode or rust like aluminum or iron, so it does not require regular maintenance like those metals do. Steel also has a high tensile strength and low thermal expansion rate, meaning that it can stand up against strong winds and extreme temperatures without warping or cracking. However, steel is heavy compared to other metals and may require heavier support structures when installing into an existing structure.


Iron is another popular option for outdoor enclosures due to its strength and affordability. Iron can withstand high temperatures and humid conditions without rusting or corroding too quickly. The downside of iron is that it requires more maintenance than steel or aluminum because it needs regular painting to prevent corrosion from occurring over time. Additionally, iron has a higher thermal expansion rate than steel which means that this metal should not be used in places where there are significant temperature changes throughout the year.
