Metal buildings are extremely durable and last a lot longer than other types of buildings. They are completely resistant to termites, and are also much more likely to withstand extreme weather conditions than other building materials. As a result of this durability, they usually require less maintenance and tend to cost less to insure.
Many modern metal building designs feature exterior finishes other than steel. These include brick, stone, split-face block or EIFS. This means that you can be creative with your exterior finish. A metal building can be designed to be almost any shape or configuration. They have a wide variety of design flexibility.
