It remains secure and undamaged even after long-term, frequent opening, closing, and locking. The surface features a high-end fluorocarbon coating that has passed a 500-hour neutral salt spray test and a 4H hardness abrasion test, providing protection against outdoor exposure to sunlight, rain, and temperature fluctuations. It resists fading, peeling, rust, and corrosion over extended use.
