Fire Door Mortise

The HD6072 mortise is tailored explicitly for fire door mortise applications and engineering constructions where superior strength is a paramount requirement. The latch, characterized by its robust design, is meticulously crafted from monolithic die-casting 304 stainless steel, ensuring exceptional durability and resilience throughout its lifetime. This comprehensive stainless steel construction enhances its longevity and guarantees high corrosion resistance.

Similarly, the deadbolt is also constructed from premium 304 stainless steel material, showcasing a commitment to quality and reliability. Rigorous testing has demonstrated its durability, achieving an impressive lifespan of 50,000 test cycles. Furthermore, the mortise undergoes stringent fire-resistance testing, successfully enduring up to 4 hours of intense heat exposure, thus fulfilling the strict safety standards for high-end engineering projects. The HD6072 mortise's robust construction and reliable performance make it ideally suited for public spaces such as hospitals, shopping malls, and offices, where safety and security are paramount.

Construction

The HD6072 mortise's face plate and striker plate are carefully crafted from high-quality 304 stainless steel. This material offers excellent resistance to corrosion and rust and ensures a strong and durable mortise. The case is made of high-quality iron, and its sturdy structure provides additional protection for the mortise and further enhances the overall safety performance. The key components in the mortise-latch, deadbolt, and spindle follower-are all molded in one piece using die-casting 304 stainless steel. This casting process not only ensures the accuracy and consistency of the components but also dramatically improves their strength and durability.

Security

After rigorous and extensive testing, the HD6072 mortise has fully complied with the demanding standards specified in QB-T 2474-2017. This thorough certification underscores its sturdy construction and exceptional performance capabilities.

Durability

The HD6072 mortise has undergone the demanding tests stipulated in QB-T 2474-2017, showcasing its remarkable resilience against prolonged use and wear. This ensures long-lasting performance and durability.
