Abstract

A structural member includes a simulated surface appearance. The structural member includes a substrate, plural intermediate layers, and a top coat. The plural intermediate layers are applied over at least one surface of the substrate, with at least some of the plural intermediate layers configured to cooperate with each other to provide a simulated appearance for the structural member. The top coat is applied outward of the plural intermediate layers. The top coat is relatively thin and is configured for use with exterior applications. The top coat includes a base configured for UV resistance and an additive configured to provide abrasion resistance.

First claim

What is claimed is:

1. A method for providing a simulated appearance to a structural member, the method comprising: providing a substrate; applying plural intermediate layers including a print layer to the substrate, the print layer including plural sublayers individually applied and stacked vertically on top of one another, the plural sublayers either at least partially transparent or translucent to light in the visible spectrum and configured to provide a wood grain appearance, wherein a first portion of the wood grain appearance is provided by a first sublayer, and a different, second portion of the wood grain appearance is provided by a second sublayer; and applying a top coat outward of the plural intermediate layers.

2. The method of claim 1 , wherein a base of the top coat comprises a fluoropolymer and the additive comprises plural inorganic particles.

3. The method of claim 2 , wherein the fluoropolymer comprises Polyvinylidene Fluoride (PVDF) and the inorganic particles comprise an Aluminum Oxide (Al 2 O 3 ).

4. The method of claim 1 , wherein the intermediate layers comprise a print undertone layer interposed between the print layer and the substrate, the print undertone layer configured to simulate a base color that is lighter than a color of the wood grain appearance.

5. The method of claim 1 , further comprising providing a foil comprising the plural intermediate layers, wherein applying the plural intermediate layers comprises applying the foil to the substrate.

6. The method of claim 1 , wherein applying the plural intermediate layers comprises thermally applying the plural intermediate layers and wherein applying the top coat comprises at least one of spraying or curtain coating the top coat over an exterior of the plural intermediate layers.

7. The method of claim 1 , further comprising curing the top coat after the top coat is applied, wherein the curing is configured to lock in a positioning of the additive with the base.

8. The method of claim 1 , wherein the plural sublayers provide the appearance of a cathedral wood grain having a leading edge, an intermediate portion, and a trailing edge, wherein the leading edge is provided by the first sublayer, the intermediate portion is provided by the second sublayer, and the trailing edge is provided by a third sublayer.
