Cold-chain doors live or die on insulation and condensation control. Cold-room construction typically specifies insulated panels in the 50–100 mm range with tight joint sealing [ESTIMATE], and the European panel benchmark shows why edges matter: a 42 mm PU panel rates U 0.5 W/m²K alone but only U 1.3 W/m²K once installed, because joints and edges create thermal bridges [SOURCED https://www.renrendoc.com/paper/308976706.html]. Panel choice, joint geometry and low-temperature seals must be engineered as one system.
RAX produces PU insulated panels on an automated foam line (standard 40–50 mm, thicker builds engineered per cold-chain project), pairs them with low-temperature-flexible silicone rubber seals, and validates complete doors from -30 °C cold storage to +50 °C desert duty. Full RAL colors, SGS material reports and traceable batch numbers ship with every order.
Cold-chain panel practice of 50–100 mm thickness and thermal-break/condensation guidance are industry conventions [ESTIMATE]. The 0.5 vs 1.3 W/m²K panel-vs-installed benchmark is published Hörmann EPU40 data [SOURCED https://www.renrendoc.com/paper/308976706.html]. RAX-specific claims are from the approved brand brief.

| Materials | Galvanized steel skins 0.4–1.5 mm around a high-fill rigid PU foam core; low-temperature silicone rubber seals; thermal-break detailing at joints to cut cold bridging [ESTIMATE]. Full RAL color, SGS material reports. |
| Color / finish | Full RAL custom (common RAL9006 / 9010 / 7016 / 5010), wood-grain, PVDF, anodizing |
| Power | Not applicable — passive, unpowered component. RAX can supply matched operators, servo drives and smart controls from its full-category one-factory range. |
| Certification | CE EN 13241 / EN 12453; product-specific test data confirmed per project |
| Order | Custom engineered to your exact opening, specification and RAL color |
Set the U-value and temperature differential first; cold rooms typically need thicker insulation (commonly 50–100 mm [ESTIMATE]) than standard 40–50 mm sectional panels.
Thermal bridges live at the joints — specify gasketed, tight-fit joints and check the installed-door U-value, not panel-only [SOURCED https://www.renrendoc.com/paper/308976706.html].
Seals, rollers and hardware must stay flexible at -30 °C; RAX validates complete door systems across that range.
Control vapor drive and surface condensation with continuous insulation and correct skin gauge; we review this at the technical drawing stage.
RAX supports full private-label production of the Cold Storage Door Panel: custom RAL panel colors, operator matching, packaging printing and installation-manual translation (EN/ES/FR/AR/RU). Start with an OEM sample and scale to container-load branded production. Custom molds, Tooling records are archived for up to 5 years — no extra tooling fee on repeat orders, all under strict NDA.
Industrial, commercial and garage doors and gates — the harmonized basis for CE marking.
Safety in use of power-operated doors — force limits and test methods for operators.
Wind (EN 12424), thermal (EN 12428), fire (EN 1634-1) etc. confirmed per product during enrichment.
Cold-chain projects typically specify thicker insulated panels — industry practice runs 50–100 mm [ESTIMATE] — with gasketed joints and low-temperature seals. RAX’s standard PU panel range is 40–50 mm, and we engineer thicker builds, seal selection and thermal-break detailing per your temperature differential. Share your room temperature and opening size for a technical drawing-confirmed proposal.
We are a pure manufacturer and do not provide on-site installation. Every order ships with an English installation manual, wiring diagrams for your local installation team; operators are pre-set and tested before dispatch.
RAX holds ISO 9001:2015 and CE to EN 13241 (industrial door product standard) and EN 12453 (operator safety), with SGS material reports and product liability insurance. Components are engineered to help the finished door satisfy EN 12604 (mechanical aspects: strength, cycle durability, finger-pinch and spring/cable safety), and product-specific test data (fire, wind, thermal) is confirmed per project against the matching standard.
Yes. RAL panel colors, operator matching, packaging printing and manual translation (EN/ES/FR/AR/RU) are all supported, from an OEM sample to container-load branded production.
Sample 7–15 days; standard container 12–20 days; custom first order 20–35 days. Door body 2-year warranty, operator/motor 3 years (servo 5 years), with spare parts dispatched by DHL/FedEx within warranty.
Factory inspection report, 100,000-cycle fatigue test record, FAI / pre-assembly photos, English installation Manual + Wiring diagrams, CE Declaration of Conformity, and export packing (steel frame + pearl cotton + stretch film).
