Frostlink single-opening plastic lock swing doors feature a prefabricated, integrated structure for easy and quick installation, while meeting all core technical requirements for cold storage doors. The door body is primarily constructed from flexible PVC plastic profiles, with an internal magnetic sealing strip. The internal polyurethane foam molding process eliminates thermal bridges, providing excellent insulation performance.
These doors are particularly suitable for the renovation and expansion of cold storage facilities, low-temperature processing workshops, insulation systems, and prefabricated panel warehouses, as well as for maintenance applications requiring only door replacement. The aluminum alloy frame can be assembled on-site with the warehouse panels, offering flexibility and efficiency, and is widely used in food processing, supermarkets, cold storage, pharmaceuticals, and retail industries.


High-density polyurethane foam core (40kg/m³ ±2) + thermal break aluminum frame eliminate cold bridges, delivering excellent heat resistance and significantly reducing energy loss.
Multi-layer EPDM gaskets (triple-layer where applicable) ensure tight compression and superior airtightness, minimizing air leakage and maintaining stable temperatures.
Standard emergency escape lock + internal handle for personnel safety; full customization in size, thickness, material, and optional features (heating, electric drive, air curtain) to meet exact project requirements.
Anodized aluminum alloy frames, high-grade nylon hardware, and anti-corrosion treatment provide strong durability against moisture, low temperatures, and daily wear.

The embedded track core with lifting block mechanism is sourced from proven international design standards. It minimizes friction and ensures smooth, stable sliding even for heavier panels, providing effortless daily operation and ultra-quiet performance in noise-sensitive environments.
Each part — from aluminum profiles and hardware to EPDM gaskets and polyurethane foam — undergoes strict multi-stage inspection, including dimensional accuracy, surface treatment, sealing compression, and thermal performance testing, guaranteeing consistent quality and reliability.
Doors are 100% built-to-order: exact size, thickness (75–200 mm), panel material (color steel, stainless steel, embossed aluminum), opening direction, hardware configuration, heating system, and optional accessories are all customizable to perfectly match your project requirements.
Standardized production processes combined with efficient supply chain management enable short lead times (typically 4–8 weeks depending on customization). We also provide detailed installation guides, on-site training, and optional professional installation supervision to ensure correct setup and optimal performance.
Every door comes with a full 12-month warranty covering manufacturing defects. We maintain a comprehensive spare parts inventory for all models, offering long-term availability (5+ years) for tracks, seals, hardware, and other components, minimizing future downtime and maintenance costs.
