Insulated sectional doors typically run 40-50 mm PU panels with whole-door U-values around 0.5 W/m²K and torsion-spring life from 30,000 cycles upward. RAX manufactures 20 sectional door models in-house – 40-50 mm CFC-free PU panels, full RAL color-consistent batch production, a 100,000-Cycle Durability Guarantee, and any size, fully engineered to your specification.
A sectional door is a long-life building envelope asset, so buyers weigh thermal compliance, spring durability, safety liability and finish consistency over years of service. The recurring problems we solve are thermal loss and energy non-compliance, premature spring fatigue in high-cycle industrial use, finger-pinch and drop safety exposure, limited headroom or odd openings, and corrosion in washdown or coastal sites. As a pure manufacturer (no on-site installation), RAX ships every door with English manuals and wiring diagrams for your local team.

Integrity note: “Industry range & sourced benchmarks” values are drawn from published competitor specifications and standards bodies (see research dossier sources) and are not RAX test results. RAX capability values reflect our manufacturing specifications and positioning; the U-Value 0.33 line and model-specific EN test reports (U-value, wind-load class, acoustic dB, fire EI class) are provided per project on request.
Standards are the trust core of a sectional door purchase. These are the European and international frameworks that govern mechanical safety, powered-door safety, wind load and acoustic/fire performance.
The CE product standard for industrial, commercial and garage doors. Covers mechanical safety (operating effort, structural strength, repeated-use durability, safe glazing) and power-operated safety (pinch/shear/draw-in protection, controlled forces, stopping behaviour, EMC), plus water penetration, wind pressure resistance, thermal resistance (U-value) and air permeability. CE conformity requires initial type assessment plus factory production control, with documentation retained 10 years.
Requirements and test methods for the mechanical safety of doors/gates – central to sectional-door mechanical safety: panel joints, springs, tracks and entrapment geometry. RAX’s finger-safe and anti-drop designs address this standard.
Defines safety requirements for powered door operation – operating forces and entrapment protection. RAX cites EN 12453 operator safety within its CE scope.
Classification (Class 0-5) and test method for the wind-load resistance of doors. Class 0 denotes no wind-load performance; Class 5 is exceptional, above 1000 Pa, agreed between maker and buyer.
Test bases referenced for acoustic insulation (dB) and fire behaviour (B-class) of door assemblies – commonly cited in industrial sectional door listings alongside the EN/EI framework.
RAX can support AS/NZS 4505 (Australia) and UL (North America) counterpart test data for market-specific compliance.
Logistics parks, 4S shops, aircraft hangars, warehouses, commercial garage projects, cold storage and fire compartments – engineered and tested from −30°C cold storage to +50°C desert conditions.
Insulated, high-cycle sectional doors for dock and bay openings where thermal compliance and spring durability drive operating cost.
Full-vision aluminum and RAL-consistent finishes that turn the door into a premium, daylight-filled facade for vehicle display.

Clear width × height (mm) plus available headroom and side room – this selects the lift type (standard / high / vertical / low-headroom / side-sliding).
Cycles per day / duty. High-usage industrial openings need high-cycle torsion springs; this drives spring rating and operator selection.
Target U-value and energy-compliance goal, plus any cold-storage setpoint – governs panel thickness (40-50 mm+) and perimeter sealing.
Site wind exposure and opening size, mapped to EN 12424 Class 0-5. Large, exposed and coastal doors need a defined class.
Finger-safe joints, anti-drop system, photo-eyes, and any fire-rating requirement (EI60 / EI120) for compartmentation.

Insulated sectional doors typically use 40-50 mm PU panels; a 40-42 mm panel commonly achieves panel U ≈ 0.5-0.6 W/m²K, with whole-door U (including joints and glazing) higher. Premium EU brands publish U-values of 0.5 / 0.9 / 1.3 W/m²K across configurations. RAX manufactures 40-50 mm CFC-free PU panels and markets U-Value 0.33 W/m²K as a positioning line – we provide the verified whole-door U-value for your specific build on request.
Spring life scales with grade: standard residential springs ≈ 10,000 cycles, high-cycle ≈ 25,000, and industrial/high-usage springs ≈ 50,000-100,000+. A typical mid-grade industrial door lists 30,000 cycles. RAX supplies high-cycle torsion springs from its in-house component range and backs the door with a 100,000-Cycle Durability Guarantee validated in our fatigue lab.
We manufacture all five standard configurations: standard lift (most common), high lift (extra vertical rise for high ceilings), vertical lift (no horizontal run for high headroom), low-headroom/compact (minimised headroom via compact track), and side-sliding (no overhead space at all). Send us your headroom and side-room dimensions and we select the right geometry.
Yes. Finger-safe panel joint geometry that prevents finger-trap gaps is a core EN 12604 / EN 12453 compliance feature, and EN 13241 covers pinch/shear/draw-in protection. We offer a dedicated finger-safe sectional door plus an anti-drop safety system that arrests the door on cable or spring failure.
Wind load is classified under EN 12424 / EN 12444 from Class 0 (no performance) to Class 5 (exceptional, above 1000 Pa); we engineer wind-load rated models to the class your site exposure requires. For fire compartmentation we offer EI60 / EI120 fire-rating capability on the fire-resistant variant, certified per project.
Yes. RAX runs RAL color-consistent batch production with full RAL custom (common RAL9006 silver grey, RAL9010 white, RAL7016 dark grey, RAL5010 blue), plus wood-grain transfer, PVDF coating and anodizing. Panel surfaces include flat, ribbed, cassette and orange-peel.
