In the first embodiment, a staircase repair device or kit is provided which includes two components, namely, a stair tread repair member and a riser repair member. These; members are placed on an existing staircase to provide a protective covering. In the second embodiment, a new staircase construction is provided which includes a plurality of stair tread members spanning between standard stringers. The components of the first embodiment and the stair tread member of the second embodiment are made of metal bent to desired shapes. Each is coated with a synthetic material to encapsulate them therein. A slip-free wearing surface is formed by a layer of particles placed over the first coating, and a second coating of synthetic material which is applied over the dispersed layer of particles. The methods of fabrication include providing the sheets of metal, bending the sheets to a desired shape, spraying the sheets with a first coating to encapsulate them therein, sprinkling a layer of particles on the upper wearing surfaces of the sheets, and then spraying a second coating over the particles to encapsulate them between the first and second coatings. |
