armored doors are widely welcomed in modern architecture due to their excellent safety and decorative features. However, its fire resistance performance is also a key concern for users. This article will explore in detail the fire resistance performance of armored doors from two aspects: material and craftsmanship.

1. Material selection

Armored doors usually use high-strength cold-rolled steel plates as the basic core, which not only provide good structural strength and anti-theft performance, but also have excellent fire resistance characteristics. The filling material for the door core is usually inorganic materials such as expanded perlite, which have good insulation and flame retardant effects, and can effectively block the spread of heat and flames in the event of a fire. In addition, the hardware accessories and sealing strips of the armored door have also undergone special flame retardant treatment to ensure stable performance even in high temperature environments.

2. Process design

The production process of armored doors is complex and refined, ensuring their excellent performance in fire resistance. The steel core inside the door leaf is composed of double-layer thickened electrolytic steel plate and high-strength keel, and filled with insulation, sound insulation, and fireproof materials. This structural design not only improves the overall strength of the door, but also enhances its fire resistance. The stainless steel edging design around the door leaf not only enhances the aesthetic appeal of the door, but also further improves its fire and moisture resistance performance.

3. Fire performance testing

In actual testing, qualified armored doors can maintain good integrity in high temperature environments, with a single point temperature rise not exceeding 180 ℃, an average temperature not exceeding 140 ℃, and no burning through phenomenon. This performance ensures that the armored door can buy valuable time for personnel evacuation and escape in the event of a fire.

4. Practical application

The fire resistance of armored doors makes them an ideal choice for homes and commercial spaces. Armored doors can provide comprehensive security in areas with frequent fires or places with high safety requirements, such as high-end residential buildings, office buildings, and hotels.

Armored doors, with their high-quality materials and exquisite craftsmanship, perform outstandingly in terms of fire resistance. Choosing armored doors is not only an investment in the safety of homes and commercial spaces, but also a responsibility for life and property.
