All metal menu covers as well as powder coated menu covers are engravable. An industrial diamond is used to engrave your logo or company name. Since engraving actually deforms the material the result is extremely durable.
Basically an engraving consists of line shapes. By combining multiple lines in a chosen pattern a contiguous area can be filled.
Engravings have a silver-colored sparkling appearance due to the nature of the underlying (aluminum) material.
