What materials are fire door handles made from to withstand extreme temperatures?


Fire door handles are made from materials that can withstand extreme temperatures, ensuring they remain functional during a fire emergency. Some of the most common materials used include:


Stainless Steel: Known for its strength, durability, and resistance to high temperatures, stainless steel is a popular choice for fire rated door handles. It can endure prolonged exposure to heat without warping or losing its functionality.


Brass: Brass is another material used for fire rated door handle sets. It has good heat resistance and is resistant to corrosion, making it a reliable choice for fire safety applications.


Aluminum: While not as heat-resistant as stainless steel, aluminum is sometimes used for fire exit door handles. It is lightweight yet strong, though it may require additional coatings or reinforcements to improve its fire-resistance capabilities.


Cast Iron: In some cases, cast iron is used for fire door handles, especially when they need to withstand very high temperatures. It offers superior strength and heat resistance.


Zinc-Alloy: Some fire door handles are made from zinc-alloy, which is heat resistant and offers a good balance between strength and durability under high temperatures.


These materials ensure that fire door handles can perform reliably during a fire, providing secure operation and allowing easy exit in emergencies.
