PU (polyurethane) insulated panels are the core of modern sectional overhead doors: two galvanized steel skins bonded around a rigid PU foam core. The reference benchmark is a leading European maker’s EPU40 sectional panel — 42 mm thick, 0.7–0.75 mm steel skins, panel-only U-value 0.5 W/m²K, assembled-panel 0.9 and installed-door 1.3 W/m²K [SOURCED https://www.renrendoc.com/paper/308976706.html]. That gap between panel-only and installed U-value is why serious OEM buyers specify skin gauge, foam fill and joint geometry together rather than panel thickness alone.
RAX runs an automated PU foam panel line producing insulated panels in 40–50 mm thickness on galvanized steel substrate (0.4–1.5 mm), with flat, ribbed, cassette or orange-peel surfaces, full RAL batch-consistent color, wood-grain transfer, PVDF coating and anodizing. Every panel batch ships with SGS material reports, dimensional technical drawings and traceable batch numbers — validated across projects from -30 °C cold storage to +50 °C desert climates.
Benchmark figures (42 mm panel, 0.7–0.75 mm skins, U 0.5 / 0.9 / 1.3 W/m²K, widths to 5,000 mm) are published data for the Hörmann EPU40 panel [SOURCED https://www.renrendoc.com/paper/308976706.html]. Industry-typical PU foam density ≈40–50 kg/m³ is an [ESTIMATE] pending RAX datasheet values. RAX-specific claims are from the approved brand brief.
Custom width × height, RAL color and configuration. Large industrial doors from prototype to container-load, full flexibility on order quantity.
Validated against a 100,000-cycle fatigue testing protocol in our in-house lab.
ISO 9001:2015 and CE to EN 13241 / EN 12453, with SGS material reports.
English manual + wiring diagrams; operators pre-set before dispatch.
| Product | PU Insulated Door Panel |
| Category | OEM Door Components |
| Size range | Panel thickness 40–50 mm (RAX standard range); cut to your panel width × height and hinge/hardware punching. As a benchmark, a leading European 42 mm panel runs to 5,000 mm width (5,500 mm motorized) × 2,500 mm height [SOURCED https://www.renrendoc.com/paper/308976706.html]; RAX manufactures to your drawings. |
| Materials | Galvanized steel skins 0.4–1.5 mm bonded to a rigid PU foam core (40–50 mm). Market benchmark for premium panels is 42 mm with 0.7–0.75 mm skins [SOURCED https://www.renrendoc.com/paper/308976706.html]. Surfaces: flat / ribbed / cassette / orange-peel; wood-grain transfer, PVDF coating, full RAL color. |
| 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 |
Choose 40 / 42 / 45 mm against your insulation target. The European benchmark 42 mm panel achieves U 0.5 W/m²K panel-only but U 1.3 installed [SOURCED https://www.renrendoc.com/paper/308976706.html] — specify the installed-door value, not panel-only.
Match gauge to door size and duty: RAX supplies 0.4–1.5 mm substrates; commercial/industrial panels typically use 0.5–0.75 mm skins [ESTIMATE].
Flat, ribbed, cassette or orange-peel embossing with full RAL batch consistency; wood-grain transfer for residential looks.
Tongue-and-groove joint geometry, hinge-side reinforcement and repeatable dimensional accuracy keep your assembly line running without rework.
RAX supports full private-label production of the PU Insulated 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.
RAX PU insulated panels run 40–50 mm thick, cut to your panel width × height with hinge and hardware punching to your drawings. As a market benchmark, a leading European 42 mm panel uses 0.7–0.75 mm steel skins and runs to 5,000 mm width [SOURCED https://www.renrendoc.com/paper/308976706.html]. Send your door size for a technical drawing confirmation — large industrial orders engineered for deep customization, full flexibility on order quantity.
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.
