Insulated swing door for pedestrian and service openings — also searched as cold room swing door and cold storage pedestrian swing door.
A compact, self-closing insulated swing door for the people-and-trolley openings that don’t need a full sliding leaf. Thick PU panel, full-perimeter seal, internal safety release and a heated-frame option for freezer rooms — built to your opening from prototype to full production runs.
One idea: not every cold room opening needs a sliding door. For staff doors, small service hatches and rooms where wall space beside the opening is short, an insulated swing door is the simpler, tighter and lower-cost seal.
A sliding door needs a clear wall to park against; a hinged door only needs the opening itself. That makes the swing door the right answer for pedestrian access, anterooms and tight plant rooms where a sliding leaf simply has nowhere to go. Self-closing hinges pull the leaf back onto its gasket every time, so the seal is never left open by accident.
RAX builds the door single- or double-leaf, with an internal safety release so nobody can be locked in, a vision window for safety at the opening, and a heated frame for sub-zero rooms. Panel thickness and the final thermal figure are confirmed on your specification, and every unit is made to order from a single door, in any size and any RAL colour.
Temperature bands and panel-thickness guidance are industry-typical ranges for cold room construction; RAX confirms the exact rating for your room per project. The U-value is stated as a “down to” marketing reference for the insulated panel, not a tested door-set figure. RAX products are validated from −30 °C cold storage to +50 °C desert conditions.
Every door is engineered to your opening and your room temperature. The values below are the validated baseline; final figures are confirmed on your specification. Each row states whether the value is RAX-measured, industry-typical or set per project.
| Parameter | Specification | Basis |
|---|---|---|
| Door Type | Insulated hinged / swing cold room door, single or double leaf. | Product definition |

Need a U-value, air-permeability or fire figure certified for tender? We arrange third-party test data against the matching standard per project — see Compliance below.
Validated substrates, processed in-house on an auto PU foam panel line and CNC punching/bending centre. Hinges, latch and safety release are matched to the panel as one assembly.
Pedestrian and service openings where a swing leaf is the simplest tight seal.
Your installers get the full document set before the door ships — the same package our EPC and distributor clients rely on.
Certificates we hold today, and the project-specific test data we arrange against the matching standard. We state held vs. per-project so you can tender honestly.
Rigorous 100,000-cycle fatigue testing, validated galvanized steel and aluminum alloy materials, and precision manufacturing — performed in-house, not outsourced.
Large industrial doors from prototype to container-load delivery. Start with an OEM sample and scale to container-load branded production.
Every hinged cold room door is built to your opening and your room. Send the clear opening size, single- or double-leaf preference, the room temperature band and any washdown or hygiene requirement (or site photos) and our engineers return a proposal, technical confirmation and lead time.
From custom engineering to container-load delivery — the document set your local installers need.
Warranty: door body 2 years · operator/motor 3 years · servo motor 5 years. Free spare parts within warranty (DHL/FedEx 5–7 days). Lead time: sample 7–15 days · standard container 12–20 days · custom first order 20–35 days.
A hinged door is the better choice for pedestrian and service openings where wall space beside the opening is limited, so a sliding leaf has nowhere to park. It is also simpler and lower cost for smaller openings. For wide, high-traffic openings used by forklifts and pallets, a sliding door is usually the better fit.
No. Every hinged cold room door carries an internal safety release that opens the door from inside the room without a key, so nobody can be trapped. A clear PVC or polycarbonate vision window is available so people on both sides of the door can see each other before opening.
Yes. The door uses self-closing hinges with a cam-lift action: as the leaf swings shut it lifts slightly and then settles onto its perimeter gasket, so the seal is re-engaged after every pass and the door is not left ajar by accident.
Yes. For frozen rooms at −18 to −25 °C we specify a thicker 150 or 200 mm panel and add a heated frame so the gasket seating stays ice-free and the seal stays flexible. RAX products are validated from −30 °C cold storage to +50 °C desert conditions, and we confirm the rating for your room per project.
RAX holds ISO 9001:2015, CE marking against EN 13241 (industrial door product standard) and EN 12453 (operator safety), plus SGS material reports and Product Liability Insurance. Fire rating (EI60/EI120) and AS/NZS 4505 / UL counterpart test data are arranged per project, not held as standing certificates.
Yes. Every door is engineered to your clear opening, single- or double-leaf, fully custom-engineered to your opening in any RAL colour. Full OEM/ODM is supported — private label, packaging printing and manual translation (EN/ES/FR/AR/RU) — under strict NDA.
Sample orders run 7–15 days, a standard container 12–20 days, and a custom first order 20–35 days (repeat custom orders 15–20 days). FOB ports are Tianjin and Qingdao; FCL and LCL are both supported. The door body is warranted for 2 years and the operator/motor for 3 years (servo motor 5 years), with free spare parts shipped by DHL/FedEx within warranty.
Every order includes wiring diagrams, an English installation manual, FAI first-article confirmation and pre-assembly photos, a factory inspection report (insulation resistance, noise, visual and function tests), the 100,000-cycle fatigue test video/report, and the CE Declaration of Conformity with the EN 13241 test report.
Send your opening size (W × H), single- or double-leaf preference and room temperature band. Our engineers reply with a proposal and lead time — no obligation.
