Abstract
A method of fabricating a tread plate having alternating stripes incorporated thereon is disclosed. The tread plate is comprised of a base plate typically formed from a metallic extrusion. Alternating stripes of resinous material are placed on the base plate and are angularly positioned thereon with respect to the longitudinal axis of the base plate. The alternating stripes of resinous material have a coloring pigment incorporated therein permitting the alternating stripes of resinous material to provide a visual warning to individuals of the existence of a potentially hazardous condition or situation when the tread plate is installed in a particular location.
Claims9
1) A method of fabricating a tread plate having alternating stripes incorporated thereon comprising the steps of:
- a) Marking an edge of the tread plate in predetermined substantially equal increments;
- b) Positioning an angle indicator adjacent each of said predetermined equal increment markings on said edge of the tread plate;
- c) Scribing a line along a predetermined angle defined by said angle indicator from each of said predetermined substantially equal increment markings on said edge of the tread plate to the opposite edge of the tread plate so as to define incremental spaces of substantially equal area on the tread plate;
- d) Placing a covering in every alternating incremental space on the tread plate;
- e) Filling the uncovered areas on the tread plate with a first resinous material;
- f) Removing said covering from said alternating incremental spaces on the tread plate so as to reveal angularly oriented stripes of said first resinous material on the tread plate;
- g) Placing a covering on the surface of said angularly oriented stripes of said first resinous material on the tread plate;
- h) Filling the spaces between said angularly oriented stripes of said first resinous material with a second resinous material;
- and
- i) Removing said covering from the surface of said angularly oriented stripes of said first resinous material.
