Made in the USA. Are you looking for that traditional engraved look? You know…when the engraving is actually engraved into the material instead of printed or burned? Then you’re looking for Diamond Etched Engraving! Diamond Etching is a specific technique used in engraving designs. Diamond Etched Engraving is also known as “Scratch Engraving” or “Diamond Drag Engraving.” This is because during the engraving process, a diamond engraver drags across the surface of the object to produce the engraved design. Unlike laser engraving or sublimation, the image is cut into the metal in such a way that light reflects off of the design. This creates a depth and brilliance that sets diamond etching apart from any other engraving method. This is by far the most durable engraving style and will never peel or fade like others sometimes do. Simply put, the design will last forever. Plates are made with the highest quality .040 aluminum. They are weatherproof, rust proof and able to withstand the harshest of road conditions. Includes a 3-year manufacturer warranty.
