Products Description
Our custom-made sliding cold storage doors effectively minimize cooling loss and are suitable for a wide range of refrigerated and frozen warehouses. Equipped with an internal emergency release mechanism and a heated door frame, the doors prevent personnel entrapment and operational jams caused by ice buildup.
Dual EPDM seals and heavy-duty sliding hardware ensure long-term operational stability.
The product is available in both manual and automatic versions. The door panel is made of color-coated steel sheet (PPGI) or stainless steel and filled with fluorine-free polyurethane (PU) or polyisocyanurate (PIR) insulation material. We also support size customization to meet the needs of food, logistics and pharmaceutical cold chain warehousing.

Sliding Door Workshop
We manufacture cold storage sliding doors following standardized production workflows for reliable quality.
Based on custom specs, we cut sheets and weld reinforced frames before injecting high-density PU/PIR foam insulation. We fit anti-freezing heating wires and double EPDM seals for tight cold retention. Heavy-duty sliding hardware and safety emergency parts are installed strictly. Electric sliding models are equipped with complete drive and safety sensor systems.
Every finished door goes through inspection before delivery to match your cold room project requirements.
