This stable insulation helps preserve the freshness texture and nutritional value of seafood products while reducing energy consumption of refrigeration equipment. The door maintains consistent performance even in long-term low-temperature operation, avoiding temperature fluctuations that could damage seafood quality. It supports a wide working temperature range suitable for both chilled storage and frozen storage areas, making it a universal solution for various seafood preservation needs.
Food Grade Safe and Hygienic Design
All PVC materials used in this swing door meet international food contact safety standards, making them fully suitable for direct use in seafood processing and storage areas. The non-toxic odorless and corrosion-resistant surface does not react with seafood juices or cleaning agents, ensuring no contamination to stored products. The smooth non-porous surface of PVC panels resists the adhesion of oil stains blood water and bacteria, supporting quick and thorough cleaning. The door structure has no hidden gaps or dead corners where dirt or moisture can accumulate, complying with strict hygiene requirements of seafood cold chains. It also resists mold and mildew growth in high-humidity seafood storage environments, keeping the storage space clean and safe throughout the product life cycle.
Low Temperature Flexibility and Durability
Unlike ordinary plastic materials that become brittle and cracked in freezing conditions, this PVC swing door uses specially formulated low-temperature resistant PVC that remains flexible and tough down to minus 25 degrees Celsius. It will not deform harden or break even under long-term exposure to frozen seafood storage environments, ensuring reliable operation year-round. The door panel has high tensile strength and impact resistance to withstand daily collisions from trolleys carts and packaging goods. The reinforced edge design prevents tearing or damage during frequent use. The hinge and hardware systems are made of anti-rust and anti-freeze materials, maintaining smooth opening and closing without jamming or failure in low temperatures. The overall structure is built for long service life with minimal maintenance needs.
Convenient Operation and High Traffic Adaptability
The PVC cold room swing door features a user-friendly bi-directional swing design that allows easy passage for workers and handling equipment with a light push. It supports 180-degree smooth swinging to maximize passage efficiency in busy seafood storage and logistics areas. The built-in automatic closing mechanism ensures the door returns to closed position quickly after each pass, minimizing cold air loss. The door operates silently without harsh noise, creating a comfortable working environment. It can be installed as a single-leaf or double-leaf structure based on passage width requirements, adapting to different layout sizes of seafood cold storage facilities. The lightweight yet sturdy design reduces operator fatigue during frequent daily use.

FAQ
1. What is a cold storage swing door (often called a "free door")?
A cold storage swing door is a double-acting door designed for high-traffic areas. It can open 180 degrees (in both directions) and closes automatically using gravity hinges. It is designed to separate different temperature zones while allowing people and forklifts to pass through quickly.
2. What are the other names for a cold storage swing door?
In the industry, these are also known as Traffic Doors, Impact Doors, Crash Doors, Double Acting Doors, or Service Doors.
3. What is the main difference between a swing door and a sliding cold room door?
A sliding door provides a tighter thermal seal and is meant for storage rooms that are not opened frequently. A swing (traffic) door is designed for processing areas or loading docks with high frequency of entry/exit, prioritizing speed and workflow efficiency over a hermetic seal.
4. Can forklifts drive directly through these doors?
Yes, provided the door is equipped with protective bumpers (kick plates). The doors are designed to absorb impact and swing open when pushed by a forklift or pallet jack.
5. Are cold storage swing doors suitable for deep freeze (-20°C) applications?
Generally, swing doors are best for chillers (0°C to 10°C), food processing rooms, and loading docks. For deep freezers, we recommend a heavy-duty sliding door with heater wires to prevent freezing shut, although some insulated traffic doors can be used in mild freezer applications.
6. Do these doors help with energy saving?
Yes. By closing automatically and immediately after a person passes through, they minimize the infiltration of warm air and humidity, significantly reducing the load on your refrigeration system compared to keeping a door propped open.
7. Are your doors compliant with food safety standards (HACCP/GMP)?
Yes. Our doors are designed with smooth surfaces, no visible screws (where bacteria can hide), and food-grade materials like #304 Stainless Steel, making them easy to clean and compliant with international food hygiene standards.
8. What is the standard thickness of the door panel?
Our standard impact traffic doors typically feature a panel thickness of 40mm, which provides a good balance between insulation and lightweight operation.
9. What insulation material is used inside the door?
We use high-density Polyurethane (PU) foam injected under high pressure. This provides excellent thermal insulation and structural strength.
10. What material is the door surface made of?
Customers can choose between 304 Stainless Steel (best for hygiene and durability) or Painted Galvanized Steel (cost-effective). We also offer ABS or PE facing for specific impact requirements.
11. How does the "Gravity Hinge" system work?
Unlike spring hinges that can wear out, a Gravity Hinge uses the weight of the door to close it. When the door is pushed open, it rises slightly; gravity then pulls it back to the closed center position. This system is extremely durable and virtually maintenance-free.
12. Can the door stay open if needed (Hold-Open feature)?
Yes. The hinge design allows the door to "dwell" or stay open when pushed past 90 degrees. This is useful during sustained loading periods.
13. Are the windows on the door shatterproof?
Yes. We use double-glazed acrylic or polycarbonate windows. They are designed to be shatter-resistant for safety in busy industrial environments.
14. What are the "Bumpers" or "Kick Plates" made of?
We use high-impact PE (Polyethylene) or PVC sheets. These are installed on the lower half of the door to protect the stainless steel panel from scratches and dents caused by carts and forklifts.
15. What type of seal is used around the door edges?
We use high-quality, tear-resistant rubber gaskets along the vertical edges to prevent air leakage. These gaskets are easily replaceable.
16. Can these doors be installed on sandwich panel walls?
Yes, but the wall opening requires reinforcement. We recommend installing a C-channel sub-frame (aluminum or steel) inside the panel opening to support the weight and movement of the door.
17. Do you offer single-leaf and double-leaf options?
Yes. For narrow openings (under 1.2m wide), we recommend a Single Leaf door. For wider openings (up to 2.4m or more), a Double Leaf door is required.
18. Can I customize the size of the window?
Yes, while we have standard window sizes, we can customize the vision panel size or shape based on your specific requirements.
19. How do I measure the opening for a swing door?
We need the Clean Opening Width and Clean Opening Height (finish-to-finish dimensions). If you have a sub-frame installed, please measure the inside of the frame.
20. Is the installation process difficult?
No, it is relatively straightforward. The door frame is mounted to the wall, and the door leaves drop onto the hinge pins. Detailed installation manuals and video guides are provided with every order.
21. How long is the warranty period?
We provide a standard 1-year warranty on the door panel and hardware against manufacturing defects.
22. Do the hinges require lubrication?
Our gravity hinges are designed to be self-lubricating or use nylon bearings, requiring very little maintenance. However, applying a food-safe grease once a year ensures smooth operation.
23. Are spare parts (gaskets, hinges) easily available?
Yes. We stock all necessary spare parts. Since gaskets are wear-and-tear items, we can include extra sets in your initial shipment upon request.
24. What happens if the door gets scratched?
If you choose the Stainless Steel finish, minor scratches can be buffed out. For deep impacts, the bumper plates are designed to take the hit, preserving the structural integrity of the door.
25. How do you package the doors for export to prevent damage?
We use a triple-layer protection method: PE film wrapping + foam corner guards + fumigation-free plywood cases. This ensures the doors arrive scratch-free.
26. What is the Minimum Order Quantity (MOQ)?
Our MOQ is 1 set. We are happy to support both small sample orders and large project bulk orders.
27. What is the production lead time?
For standard sizes, production takes 7-10 days. For custom sizes or large quantities, it typically takes 15-20 days.
28. Can you print our company logo on the packaging?
Yes, we offer OEM services. We can label the packaging with your brand name, logo, and project reference numbers.
