Core Technical Parameters
1. Fire Rating: 2 hours (120 minutes) fire resistance, fully compliant with GB 12955-2015 Class A standard, EN 1634-1 and UL 10B international certifications, ensuring that the door leaf does not collapse, the fire does not penetrate, and the back surface temperature rise ≤140℃ within 120 minutes, meeting the strict fire safety requirements of various countries and regions.
2. Structural Dimensions: Standard sizes include 2100×900mm, 2100×1000mm, 2100×1200mm; fully customizable according to customer needs, supporting arbitrary size adjustment, and the door thickness is 50-55mm (customizable 50-70mm).
3. Door Configuration: Single leaf and double leaf options are available, with flat opening design; the door frame is integrated with the door leaf, ensuring structural stability and good fire sealing performance.
4. Production Lead Time: 10-15 working days for standard orders; expedited production service is available for urgent projects, ensuring timely delivery to meet customer project progress requirements.
Material & Manufacturing Process
The product adopts high-quality raw materials and advanced production technology, with strict quality control throughout the process, ensuring long-term durability and stable performance.
1. Panel & Door Frame Material: The door leaf panel is made of 0.8-1.5mm thick high-quality galvanized cold-rolled steel, which has strong corrosion resistance, rust resistance and impact resistance, and is suitable for the hot and dry, high-humidity climate of the Middle East; the door frame is made of 1.2-1.5mm thick thickened steel plate, which is reinforced at the installation positions of hinges, locks and door closers with 3mm thick galvanized steel plates to avoid structural deformation caused by long-term use.
2. Core Filling Material: The interior is filled with high-density fireproof rock wool (or perlite optional), which has excellent fire insulation performance, non-toxic, non-combustible, and can effectively isolate high temperature and smoke during a fire, reducing the spread of fire.
3. Sealing System: Equipped with fire-expandable sealing strips around the door leaf and door frame, which will expand rapidly when encountering high temperature (above 60℃), filling the gap between the door leaf and the door frame, and effectively blocking the penetration of smoke and flames.
4. Manufacturing Equipment: Produced by Longzhengsheng’s two large-scale production bases, using advanced equipment such as laser cutting production lines and automatic powder coating production lines, combined with ERP management system to realize flexible customized production, ensuring the precision and consistency of product dimensions and craftsmanship.
