The Logistics "Password" to Li Auto’s Changzhou Super Factory – Fastlink Industrial Doors
Industrial sectional doors are heavy-duty overhead door systems designed for commercial and industrial facilities. Constructed from reinforced steel or aluminum panels with interlocking hinges, they combine durability with space efficiency. Unlike traditional doors, they operate vertically before transitioning horizontally along ceiling-mounted tracks—eliminating the need for outward clearance. This makes them ideal for high-traffic environments like warehouses, loading docks, and manufacturing plants where reliability, security, and optimized space utilization are critical.
In such a high-standard manufacturing ecosystem, there is zero room for compromise on logistics efficiency and operational safety. That’s exactly why Fastlink Door became Li Auto’s trusted partner. Our tailor-made solution – including the day-night door combination, mechanical dock shelter, and telescopic dock leveler – serves as a critical logistics infrastructure. It not only perfectly meets the stringent demands of automotive manufacturing but has also earned high praise for its deep customization capabilities, fast delivery, and intelligent service.
The Classic Combination: Insulated Sectional Door + PVC High-Speed Door
The "outer insulated sectional + inner PVC high-speed door" dual-layer system delivers a true "double-door synergy" that dramatically enhances performance. It perfectly addresses the complex needs of NEV manufacturing – temperature control, cleanliness, and logistics throughput.
Flexible operation, efficient access
Daytime: PVC high-speed door enables fast, high-frequency traffic.
Nighttime: Insulated sectional door provides robust security and theft protection.
This flexible switching maximizes the benefits of the combined door system, making it ideal for paint shops, battery assembly lines, and other critical areas.
Insulated Sectional Door
Thermal insulation
The insulated sectional door blocks external heat, while the PVC curtain closes rapidly to minimize air exchange between indoor and outdoor spaces. Compared to single-door setups, this significantly reduces building energy consumption. The door panels feature a double-layer aluminum sheet + high-density polyurethane insulation core with a thermal conductivity ≤0.025 W/(m·K). High-quality sealing strips around the frame and between panels deliver superior airtightness.
High-strength protection
Located in a coastal typhoon-prone area (Changzhou), the door withstands wind pressure up to Typhoon Level 12 and resists salt spray corrosion for over 1,000 hours – ideal for the humid Yangtze Delta climate. Panel colors can be customized to match the factory’s aesthetic, and the door supports integration with the plant’s security system, adding both function and style.
PVC High-Speed Door (Interior Use)
The "Cleanliness Sentinel"
With an ultra-fast opening speed of 1.5 m/s, the PVC high-speed door effectively isolates dust and noise, meeting Li Auto’s stringent cleanliness requirements. Optional transparent PVC windows provide natural light and visibility, making forklift passage safer and more efficient.
Adaptive environment protection – the first line of defense
The mechanical dock shelter, a companion component to the sectional door, plays a vital role in protection, safety, and extending door life. It effectively shields against physical impacts – such as vehicle collisions or heavy scrapes – preventing door deformation and coating damage. It also provides wind, rain, and dust protection, while sealing the gap between vehicle and warehouse to improve working conditions, save energy, and support smooth indoor operations.
Hydraulic Dock Leveler
Efficient loading/unloading, safe and worry free
Seamless truck engagement: Precise height adjustment ensures zero errors when handling Li Auto’s precision components, significantly boosting dock productivity.
Slip resistant & durable: The deck uses high-strength checkered steel plate – slip resistant even in the rain – with a load capacity exceeding 10 tons, far surpassing industry durability standards.
Why Does a Single Door Matter So Much to Li Auto?
In an automotive manufacturing plant, an industrial door is far more than just a barrier. It is a core functional asset that connects safety, process integrity, logistics, and operations.
The high-speed door ensures cleanliness in precision assembly areas, providing a stable environment for critical automotive processes.
The high speed induction design perfectly accommodates AGVs and forklifts, eliminating logistics bottlenecks.
Im Bereich der Industrietore haben sich Sektionaltore aufgrund ihrer Isolierung, Witterungsbeständigkeit, Langlebigkeit und platzsparenden Bauweise als Standardlösung für Logistiklager, Kühlhäuser und Automobilwerke etabliert. Das Herzstück eines Industrietors ist jedoch der Motor. Herkömmliche Motoren, die häufig ausfallen und übermäßig viel Energie verbrauchen, stellen seit Langem ein Problem für Unternehmen dar.
