Abstract:
The present invention provides a method of coating a surface with a slip resistant coating. The method of the invention comprises either sequentially or simultaneously melting two different metal wires and directing droplets of the melted wires towards a surface to be coating. The resulting coating formed by this process tends to be rough and confers anti-slip properties to the surface. In one variation of the invention, the two different metal wires will be melted and atomized in a single spray gun. Alternatively, these wires may be melted in separate but adjacent spray guns. In either variation, the resulting metal sprays formed from the different wires will at least partially overlap.
Abstract:
A method of making grating wherein grating bars are provided with an anti-slip coating. The grating bars are placed side by side with their top edges aligned and with the sides of adjacent bars in contact with each other. The grating bars are held stationary relative to each other. Molten metal is sprayed on to the top edges to form a rough surface on the top edges. The grating bars are subsequently separated and assembled together in a spaced relationship by attaching transversely extending members to the grating bars.
Abstract:
The present invention provides a truck trailer manufacturing facility is for coating workpieces such as metal plates or grating sections with a thermal spray anti-slip coating that provides a durable, high coefficient of friction surface on the workpieces. The manufacturing facility of the invention includes at least one surface preparing machine and at least one coating machine housed in a truck trailer. The present invention also provides a method of coating a workpiece with the truch trailer manufacturing facility.
