Core Selling Points

Our lift doors are designed with five key dimensions in mind: safety, durability, intelligence, energy efficiency, and space efficiency.

1. Durable, Safe and Reliable

The door panels are constructed from double-layer galvanized steel filled with high-density polyurethane foam (40-50mm thick), providing superior impact resistance and thermal insulation. Equipped with industrial-grade motors and emergency release devices for manual operation during power outages.

Safety Grating: Immediate stop and reversal if personnel or vehicles are detected.
Safety Bottom Edge: Rubber strips that trigger an immediate rebound upon contact with obstacles.
Anti-Breakage Device: Specialized mechanisms to prevent door fall in case of wire rope or spring failure.
2. Excellent Sealing and Energy Efficiency

High-quality EPDM rubber sealing strips are installed across all joints and edges. The low thermal conductivity of the polyurethane panels significantly reduces energy loss, making them ideal for cold storage and constant temperature environments.

3. Optimized Space Utilization

Vertical lifting and parallel ceiling movement free up valuable space around the door opening. High-speed options (up to 2.0m/s) enhance logistics efficiency and maintain environmental stability.
