Now interior stairs must have the ability to handle a certain amount of poundage. They also need to have no slip grips and be 4 inches between the balusters. It makes sense to use them for decorative. Even the decorative interior stairs have safety features built right into them. They come in a wide variety of materials to match design. They come in wood, iron, glass, and other types of materials.
You can have custom interior stairs manufactured or you can even have them painted to match the color of your walls or floors. They will last the lifetime of your house if you take care of them. For example, if they are wood, they could be infected with insects or be warped if they get wet. Since you have a choice of materials like iron, glass, or aluminum you don’t have to worry about insects, but you do have to look out for rust.
