Fire Protection Grade Distinctions

Grade A doors boast a fire resistance time of ≥ 1.5 hours, making them ideal for high-risk areas. Grade B doors offer a robust resistance of ≥ 1 hour, suited for medium-risk zones, while Grade C doors provide a reliable ≥ 0.5 hours of protection, catering to low-risk areas.
