Kit of parts for trimming step edges

Apparatus for trimming a step edge for example a tread of a staircase, a step at an edge of a sunken floor, or a top edge of a short wall, comprising:

• a riser board for locating a top of the riser board disposed in upright orientation at or adjacent an edge of a substantially horizontal existing surface defining said step edge;
• an elongate member forming a nose piece for locating at the edge of the existing surface, the member including a top, a rear for facing towards the step edge, and a front ornamental face that is opposite the rear;
• a covering board for covering the existing surface;
• the covering board having a top wear surface, a bottom surface for facing the existing surface, a front edge for locating proximal the member, and a rear edge for locating distal to the member;
• the member being arrangeable in a mounted position in which the top of the member is spaced above the existing surface such that a thickness of the covering board is locatable between the top of the member and the existing surface;
• the member including a locking recess in the rear that is spaced from the top so as to leave an upper portion of the rear of the member between the recess and the top for locating at a height of the existing surface in the mounted position of the member;
• the locking recess having a base spaced inwardly from the rear of the member, a top sidewall extending from the base to the rear of the member, and a bottom sidewall opposite the top sidewall;
• and a fastener connected to the covering board and projecting forwardly of the front edge thereof at a location spaced below the top wear surface for cooperation with the locking recess to mechanically couple the covering board and the member;
• the fastener comprising a base strip having a forward edge spaced forwardly from the front edge of the covering board and supporting on a surface extending therebetween at least one deflectable projection upstanding from the surface which can deflect relative to the base strip in at least a rearward direction so as to deflect during insertion into but resist removal from within an interior space defined by the locking recess.

A method of forming a covering panel for trimming a tread of a staircase, the method comprising the steps of:

• providing a base sheet of metallic material, the base sheet having:
• a width and a length substantially equal to a width of the tread and a length thereof respectively;
• and
• an upper face for facing upwardly when the covering board is received on the tread;
• providing at least one strip of metallic material which is sized smaller than the base sheet, each strip having an upper face for facing upwardly when the covering board is received on the tread and an opposite lower face;
• bonding the lower face of the at least one strip to the upper face of the base sheet to substantially form the covering panel so that the at least one strip is fixedly located on the base sheet with its upper face spaced above the upper face of the base sheet, the step of bonding including:
• applying adhesive at an interface between the lower face of the at least one strip and the upper face of the base sheet;
• curing the adhesive at a baking temperature lying in a range between 200 and 600 degrees Fahrenheit.
