INDUSTRIAL HIGH-SPEED DOORS · LOADING DOCK EQUIPMENT
Established in 2014 as China's first high-speed spiral door manufacturer, LEFAST builds high-speed doors, cold-storage doors and loading-dock equipment for factories, warehouses, cold-chain facilities and logistics projects worldwide.
PRODUCT RANGE
From high-cycle interior separation to wind-resistant exterior openings, temperature-controlled rooms and loading docks, each system is configured around the real operating environment.
SELECT BY APPLICATION
Opening size, traffic frequency, temperature, pressure difference, wind load, hygiene requirements and activation method all influence the correct door and control configuration.
Tell Us About Your ApplicationMANUFACTURING & DELIVERY
LEFAST supports logistics and warehousing projects with door fabrication, mechanical transmission, servo control, safety protection and installation coordination under one engineering workflow.
VERIFIED PERFORMANCE
The HSD spiral-door system has been tested by China's National Construction Engineering Quality Supervision & Inspection Center for wind resistance, air permeability, watertightness, thermal insulation and sound insulation — each rated to a national-standard class. Motor, bearings and chain are rated for more than one million open-close cycles.
INSTALLED PROJECTS
Exterior industrial access, rapid interior separation and temperature-controlled storage each require a different combination of door structure, control and safety features.
PROJECT WORKFLOW
Send the opening dimensions, site photos and operating requirements. We will use them to recommend the door type, controls and safety configuration.
Confirm the opening, traffic type, cycle frequency, temperature and activation method.
Match the door structure, control system, safety protection and integration requirements.
Define the product configuration, installation conditions and commercial quotation.
Manufacture, inspect and pack the system according to the confirmed specification.
Support installation, commissioning, operation guidance and ongoing maintenance.
SOURCING FAQ
Choose a rigid spiral door for exterior access, strong wind, insulation or security. Use a roll-up door for fast interior separation and hygiene control. A stacking door is well suited to larger openings that need reinforced wind resistance.
Send the clear opening width and height, installation photos, indoor or outdoor conditions, expected daily cycles, traffic type and preferred activation method. Drawings are helpful when available.
Options include radar, induction loops, remote controls, pull cords, door interlocking, Bluetooth or RF devices, licence-plate recognition, facial recognition and fingerprint access.
Yes. Emergency manual opening is available. The operating method depends on the door model and is explained during commissioning and handover.
