Abstract
A stackable step component with adjustable tread incline includes a step frame having a top edge surface and a bottom edge surface. The top edge surface is substantially level when the bottom edge surface is in contact with an inclined ground surface. The stackable step component also comprises one or more ground penetrating features coupled to the step frame that secure the step frame to the ground surface and an adjustable tread coupled to the top edge surface. The adjustable tread allows adjustment of a tread incline angle. The step component is used to construct a stairway one step at a time without costly design intensive stringers. Each step component includes an adjustable tread so after installing, the tread incline of each step can be set to be level or at a desired angle. A quick and inexpensive outdoor stairway is constructed where each step supports at least three-hundred pounds.
