The hinges are typically made from stainless steel to provide added strength and resistance to corrosion, as stainless steel is a durable and long-lasting material that can withstand exposure to fire and smoke. Additionally, fire rated stainless steel door hinges are designed to help prevent the spread of fire and smoke, as they are typically equipped with intumescent seals that expand when exposed to high temperatures, helping to seal the gap between the door and the frame and prevent the spread of flames and smoke.
