The core unique advantage of this entry door is its Class A fire rating, which complies with national fire safety standards, solving the critical pain point of fire safety compliance for engineering projects. Unlike standard entry doors, it is constructed with 2.5mm thick fire-resistant cold-rolled steel, filled with fire-resistant mineral wool core material that prevents heat transfer and smoke penetration. The fire-rated hinges and lockset are certified to withstand high temperatures for up to 120 minutes, ensuring the door remains functional during a fire emergency. The door also features a reinforced anti-pry structure, with steel lock bolts and anti-saw plates, providing reliable anti-theft protection for residential and commercial properties. Its epoxy powder coating offers superior resistance to scratches, rust, and fading, making it suitable for high-traffic areas such as schools and hospitals. Additionally, the door’s standard engineering sizes are compatible with most construction projects, reducing installation time and costs for developers. It also meets RoHS environmental standards, ensuring no harmful substances are released into the environment.
This entry door features standard engineering sizes ranging from 72 inches (height) x 30 inches (width) to 84 inches (height) x 36 inches (width), with customizable sizes available for large-scale projects. The door panel is made of 2.5mm thick fire-resistant cold-rolled steel, filled with 50mm thick fire-resistant mineral wool core material that meets GB 8624-2012 fire safety standards. The fire rating is Class A, providing 90 minutes of fire resistance, which complies with GB 12955-2008 national fire product standards. The door is equipped with fire-rated hinges and lockset, certified to withstand temperatures up to 1000°C for 120 minutes. The sound insulation level reaches 32 dB, effectively blocking low-frequency noise from common areas. The surface finish is an epoxy powder coating that meets ASTM D3359 scratch resistance standards, with color options including white, gray, and black. The lockset is a mortise lock rated ANSI/BHMA Grade 2, with a steel lock bolt that extends 20mm for enhanced security. The door is also equipped with a fire-resistant door closer that ensures the door closes automatically, preventing the spread of fire and smoke.
This Class A fire-rated entry door is ideal for a wide range of commercial and residential engineering projects. It is primarily used in affordable housing projects, where fire safety compliance and cost-effectiveness are top priorities. It is also suitable for educational institutions such as schools and universities, providing a safe escape route for students and staff in case of a fire emergency. In healthcare facilities such as hospitals and clinics, it helps prevent the spread of fire and smoke, protecting patients and medical staff. For office buildings and commercial spaces, it meets local fire safety codes, ensuring compliance with regulatory requirements. Additionally, it can be used in industrial facilities such as warehouses and factories, where fire safety is critical. Its durable construction and anti-corrosion finish make it suitable for high-traffic areas, reducing maintenance costs for facility managers. The door’s standard engineering sizes are compatible with most construction projects, reducing installation time and labor costs. It is also a popular choice for retrofitting existing buildings to meet updated fire safety standards, providing a cost-effective solution for property owners.
