Features
Super high-strength anti-destruction structure: Adopting integral forging technology, the door panel is built with reinforcing ribs and anti-drill steel plates, the bolt diameter is ≥30mm, and multi-point linkage locking (12-20 bolts). It can resist professional tool demolition for more than 12 hours, far exceeding the protection standard of ordinary security doors.。
Multiple lock control and authority management: Supports dual-person dual-lock, triple verification and other opening modes to prevent single-person illegal operation; the intelligent version can record all door opening and closing operations and abnormal attempt records, with data storage ≥10000 entries, facilitating traceability and verification, meeting the compliance requirements of the financial industry.
Comprehensive environmental protection: The fireproof filling material is high-temperature resistant ceramic fiber with the highest fire resistance limit; the sealing strip is made of high and low temperature resistant EPDM material, which has waterproof, dustproof and sound insulation functions, and can adapt to harsh environments such as humidity and high temperature to protect internal items from damage.
Intelligent linkage and alarm function: Can be linked with video monitoring, infrared detection, smoke alarm and other equipment. When abnormally opened, it automatically triggers sound and light alarm, and synchronously pushes information to the manager's mobile phone/computer; real-time reminders for low battery, lock failure and other statuses to ensure continuous and reliable operation of the equipment.
Customized adaptation and durability: Supports personalized customization of opening size, security level, lock type and intelligent functions to meet different scenario requirements; the surface is treated with sandblasting, phosphating and electrostatic spraying, anti-corrosion and rust-proof, with a service life of more than 30 years and low maintenance cost.
