The PU Insulated Sectional Door is RAX Door Technology’s core thermal-performance product for logistics warehouses, food-processing facilities and energy-conscious industrial buildings. Each door is built with 40–50 mm thick closed-cell polyurethane (PU) foam panels — the same insulation technology that premium European brands such as Hörmann use in their EPU/LPU ranges (Hörmann specifies 42 mm panels with CFC-free PU foam). RAX produces panels on an automated PU foam line, ensuring consistent foam density and bond quality across every batch.
For reference, a comparable CN-export industrial sectional door lists 40 mm panels at 46 kg/m³ foam density, achieving a thermal transmittance of 0.38 W/m²K (source: ecer.com industrial listing). RAX’s own marketing target is U-value 0.33 W/m²K thermal performance — this is a design goal pending RAX’s own EN-tested whole-door U-value report and should not be cited as a certified lab result. Steel skins range from 0.4 to 1.5 mm galvanized sheet (brand capability); for comparison, Hörmann uses 0.7–0.75 mm steel skins on its EPU40/LPU40 panels.
RAX-company facts on this page are from the approved brand brief. Industry benchmark values are attributed to their sources (Hörmann via renrendoc.com; CN-export listings via ecer.com; EN standard scopes via antpedia.com / baijiahao). RAX product-specific test data (U-value, wind class, fire rating) is confirmed per project.

| Order | Custom engineered to your exact opening, specification and RAL color |
Provide clear opening width × height and available headroom (distance from lintel to ceiling). Standard lift requires approx. 300–600 mm headroom; we produce the confirmation drawing showing exact track geometry.
Specify your required U-value or energy-code compliance. For insulated logistics buildings, a 40–50 mm PU panel is standard. We match panel build and perimeter sealing to your climate zone and confirm against EN 12428 thermal calculation.
State expected cycles/day. For 10+ cycles/day logistics use, specify high-cycle torsion springs (validated to 100,000 cycles in our fatigue lab). Standard residential-grade springs (approx. 10,000 cycles) are not suitable for industrial duty.
Choose RAL color (batch-consistent production), panel surface profile (flat/ribbed/cassette/orange-peel) and optional wood-grain transfer. Interior face standard is light grey; exterior to your brand palette.
RAX supports full private-label production of the PU Insulated Sectional Door: 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.
Product standard for industrial, commercial and garage doors — the harmonized basis for CE marking. Covers mechanical safety, thermal resistance (U-value), air permeability, water penetration, wind resistance and durability. Technical docs retained 10 years.
Safety in use of power-operated doors (operating forces, entrapment protection) and mechanical aspects (panel joints, springs, tracks). Together they define finger-safe geometry and controlled operating forces.
Wind load resistance classification (Class 0–5) and test method. Class 0 = none (internal/shielded); Class 5 = exceptional, >1000 Pa by special agreement. Confirm required class for your site wind exposure.
Air permeability classification framework. Perimeter sealing design targets low air-leakage for energy compliance in conditioned warehouses and cold-chain buffer zones.
RAX produces 40–50 mm closed-cell PU foam panels on an automated foam line. For reference, a comparable CN-export industrial door uses 40 mm panels at 46 kg/m³ density (ecer.com listing), while Hörmann specifies 42 mm CFC-free PU panels. Exact foam density per RAX product is confirmed on request with SGS material report.
No. The 0.33 W/m²K figure is RAX’s marketing design target for thermal performance. It is pending RAX’s own EN-tested whole-door U-value report. For context, a comparable CN-export door lists 0.38 W/m²K, and Hörmann’s EPU40/LPU40 achieves 0.5–1.3 W/m²K depending on panel/joint/glazing configuration. We will provide our test report once available.
RAX validates springs in its in-house 100,000-cycle fatigue test lab. Industry benchmarks: standard residential springs approx. 10,000 cycles; mid-grade industrial 30,000 cycles (CN-export listing, ecer.com); high-cycle industrial 50,000–100,000+. Specify your cycles/day and we match the appropriate spring rating.
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.
