The Wind Load Rated Sectional Door is engineered and classified for sites with significant wind exposure — coastal logistics parks, high-rise building podiums, airport facilities and regions subject to typhoon or storm loading. Wind resistance is classified per EN 12424 (classification) and tested per EN 12444 (test method), with classes running from 0 (no requirement / internal or shielded) to 5 (exceptional, >1000 Pa by special agreement).
For industry context, a CN-export industrial sectional door lists wind resistance of 450 N/m², which corresponds approximately to Class 3 on the EN 12424 scale (source: ecer.com). Intermediate class pressures commonly cited are: Class 1 ≈ 150 Pa, Class 2 ≈ 300 Pa, Class 3 ≈ 450 Pa, Class 4 ≈ 600 Pa (industry estimate, not independently re-verified). RAX engineers wind-rated doors with reinforced panels, heavy-gauge tracks and additional bracing to meet the specified class, validating structural integrity in our 100,000-cycle fatigue lab. Panels use 40–50 mm PU foam with galvanized steel skins (0.4–1.5 mm).
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.

| Track | Heavy-gauge formed steel channel (2.0 mm+ for high classes); reinforced brackets |
| Size range | Custom to your opening (custom engineered to your specification). Larger doors require higher structural reinforcement |
| Torsion spring | High-cycle; 100,000-cycle fatigue validated |
| Power | AC 220–240 V / 380 V, 50/60 Hz |
| Certification | CE EN 13241 / EN 12453 (held); wind class confirmed per project to EN 12424 |
| Order | Custom engineered to your size and specification |
Obtain your site’s design wind pressure from local building code or structural engineer. Convert to EN 12424 class: Class 1 ≈ 150 Pa, Class 2 ≈ 300 Pa, Class 3 ≈ 450 Pa, Class 4 ≈ 600 Pa, Class 5 > 1000 Pa.
Larger doors and wider aspect ratios experience greater deflection under wind load. Provide exact W × H; we calculate panel reinforcement, track gauge and bracing requirements.
For Class 3+, RAX specifies heavier steel skins, internal panel stiffeners and reinforced track brackets. For Class 4–5, additional horizontal bracing or thicker gauge may be required.
Wind load classification per EN 12424 with test method per EN 12444. RAX provides wind load documentation as part of the CE technical file. For projects requiring third-party test reports, we arrange testing to the specified class.
RAX supports full private-label production of the Wind Load Rated 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.
Wind load resistance classification for industrial/commercial/garage doors. Classes 0–5; Class 0 = no requirement (internal/shielded); Class 5 = exceptional (>1000 Pa by special agreement).
Test method for wind load resistance — defines the pressure/deflection test procedure used to verify the classified class.
Product standard incorporating wind resistance as one of the CE marking characteristics. References EN 12424 for classification.
EN 12424 classifies door wind resistance from Class 0 (no requirement — internal or fully shielded doors) to Class 5 (exceptional, >1000 Pa, by special agreement). Intermediate classes commonly cited: Class 1 ≈ 150 Pa, Class 2 ≈ 300 Pa, Class 3 ≈ 450 Pa, Class 4 ≈ 600 Pa (industry estimate).
A CN-export industrial sectional door lists 450 N/m², approximately Class 3 (source: ecer.com). For most inland industrial sites, Class 2–3 is adequate. Coastal, high-rise or typhoon-exposed sites may require Class 4–5.
Heavier-gauge steel skins (up to 1.5 mm), internal panel stiffeners, reinforced track brackets, thicker track channel and additional horizontal bracing. The specific reinforcement package depends on door size and target class.
RAX provides wind load classification documentation as part of the CE technical file per EN 13241. For projects requiring independent third-party test reports to EN 12444, we arrange testing to the specified class.
