Steel siding might not be the first thing that pops in your mind when considering installing new siding on your commercial building, especially because in the past it has been used mostly for industrial applications. In recent years, much improvement has been made in the appearance and quality of steel siding, and it is definitely a valid option for a commercial setting.
Steel can now be found in a variety of textures and colors for you to choose from.
You do need to make a choice between galvanized and stainless steel. These are 2 different methods of preventing rust, but each has a different weakness that affects where it would be suitable.
Galvanized steel is damaged by saltwater, so it would not be ideal for a house near the ocean, but it could also be damaged by the salty wintery mix you will find on the roads in some areas of the country.
Stainless steel is damaged by chlorine, so it would not be ideal near a pool.
