What materials are used for fire protection fittings?

Fire protection hardware sets are designed to withstand doors in the event of a fire and contain the fire as effectively as possible. Various materials are used in the manufacture of fire protection hardware sets to maximize their effectiveness.

• Stainless Steel: Stainless steel is a commonly used material in fire protection hardware sets. It is extremely heat-resistant and retains its stability and shape even at high temperatures.
• Aluminum: Aluminum is a lightweight yet heat-resistant material used in many fire protection hardware sets. Its ease of processing makes it a suitable material to actively help prevent the spread of fire.
• Lock and Cylinder Escutcheons with Fire Protection: In fire protection hardware sets, lock and cylinder escutcheons made of heat-resistant material are often integrated. These serve to cover and additionally insulate the cylinder and lock.
• Special Flame-Retardant Materials: Some manufacturers also use special flame-retardant materials and components, including special seals and adhesives, which reduce heat transfer and help isolate the fire and prevent its spread.

Together, these materials help ensure the effectiveness of fire protection hardware sets and provide important protection in the event of a fire.
