Treads of stairs are traditionally all wood, cement or wrought iron. They can be made a number of ways, but houses usually have wooden frame stairs and stair treads. A stair tread does not have to be hidden by carpet. It does not have to be a plain plank of wood. In fact, a stair tread can be designed to be more visual than the basic practical function it serves, as the flat support to step on up a flight of stairs. A stair tread has the potential to be so much more. There are several stairs treads design ideas. For instance, carved stair treads. Carved hardwood stair treads are high end and not on most people’s budgets. Carved softer woods, such as pine, do not work as well since they tend to wear faster, and the carved area will weaken the treads.
