Core Comparison: Key Feature Differences Between PVC High Speed Doors vs. Spiral Doors
Thermal Insulation & Sealing Performance
Spiral High Speed Doors
Thermal Insulation: Adopts a structure of 40mm thick double-layer aluminum alloy door panels + intermediate polyurethane foam layer. This insulation performance is significantly superior to PVC doors (single-layer 0.8-1.2mm PVC material). The polyurethane foam layer effectively blocks external temperature conduction, reduces cold and hot air exchange, and is more suitable for food storage environments requiring stable temperature control.
Sealing Effect: Through rubber strip sealing and tight fitting of aluminum alloy profiles, spiral doors offer better dustproof, insect-proof, and soundproof effects, preventing food contamination from dust or odors.
PVC High Speed Rolling Doors
Thermal Insulation: PVC curtains are generally 0.8-1.2mm thick (single-layer) without additional insulation layers. Suitable for ordinary ambient temperature workshops with no special insulation requirements.
Sealing Effect: Equipped with double-row brushes inside the tracks, enabling basic dust and insect isolation to reduce external pollutants. More suitable for warehouse scenarios with clean environments and no special cleanliness requirements.
Safety & Durability
Spiral High Speed Doors
Safety: Double-layer aluminum alloy door panels have strong impact resistance. Combined with protective measures such as safety light curtains and airbag rebound devices, they can effectively prevent forklift collisions or personnel straying, ensuring higher safety.
Durability: The material is corrosion-resistant and flame-retardant (Class B2), with a long service life, suitable for high-frequency use environments.
PVC High Speed Rolling Doors
Safety: Equipped with infrared photoelectric sensors and safety airbag bottom protection for basic safety. However, the soft PVC material has weak wind resistance, impact resistance, and poor anti-theft performance, making it more suitable for indoor workshop partitions.
Durability: The soft curtain material is prone to wear and tear during long-term high-frequency use or contact with sharp goods, resulting in a relatively shorter service life.
