Arcade machines endure constant public interaction, making scratch-resistant surfaces essential for longevity. The most common protective materials include tempered glass, which provides excellent clarity and hardness against coin scratches and impacts. Polycarbonate plastic offers superior impact resistance with moderate scratch protection, often used where safety is paramount. Decorative laminate overlays combine vibrant graphics with melamine resin surfaces that resist wear from daily use. Many manufacturers apply clear protective coatings containing polymers or nano-ceramics to create invisible barriers against abrasion. These materials maintain aesthetic appeal while withstanding the rigors of commercial arcade environments, ensuring machines remain visually appealing despite heavy usage.
