Also searched as wind load rated door, high wind load industrial door and coastal wind-rated door.
An exterior door engineered to hold its shape and seal under sustained wind pressure — reinforced curtain, stiffened guides and a tested wind class for exposed, coastal and high-wind sites. Built to your opening and your wind zone, from prototype to full production runs.
One idea: on an exposed wall, the door is the weak point. A weather load rated door is built and tested to take the wind pressure that would bow, rattle and leak a standard exterior door.
Coastal warehouses, desert plants and tall exposed buildings put large exterior doors under real wind pressure. A standard door deflects, the curtain billows out of the guides, the seals open, and rain and dust get in. A weather load rated door addresses each path: a reinforced curtain or panel resists deflection, stiffened deep guides keep the edges captured, and compression seals stay closed under load — so the door keeps its rating across the whole opening, not just at the centre.
RAX engineers each door to your wind zone and opening, then confirms the achieved wind class per project on the matching test standard. Wind resistance for industrial doors is classified on the harmonized EN 12424 scale from Class 0 to Class 5; RAX markets “Wind Load Class 5 Certified” capability, and the specific class for your door is confirmed on the matching test data.
Wind resistance is classified on the harmonized EN 12424 Class 0–5 scale for industrial doors; the achieved class is confirmed per project on the matching test data. Note: RAX’s separate “Class 12” figure is a proprietary scale used for spiral high speed doors (peer soft doors rate 8–10 on that scale) and is not the EN 12424 scale. Cycle life of 100,000 cycles is validated in the RAX fatigue test lab.
Every door is engineered to your opening. The values below are the validated baseline; final figures are confirmed on your specification. Each row states whether the value is RAX-measured, an industry-typical range, or per project.
| Parameter | Specification | Basis |
|---|---|---|
| Door Type | Weather / wind load rated exterior door (roller or sectional build) | Product definition |

Need an EN 12424 class evidenced for tender or a wind-zone calculation? We arrange the matching test data per project — see Compliance below for what is held versus arranged per project.
Validated substrates, processed in-house on an auto PU foam panel line and CNC punching / bending centre. No outsourcing of the structural parts.
Exposed exterior openings where standard doors deflect, leak and fail early.
Your installers get the full document set before the door ships — the same package our EPC and distributor clients rely on.
Certificates we hold today, and the project-specific wind test data we arrange against the matching standard. We state held versus per-project so you can tender honestly.
Rigorous 100,000-cycle fatigue testing, validated galvanized steel and aluminum alloy materials, and precision manufacturing — performed in-house, with the wind class confirmed per project on the matching test data.
Large industrial doors from prototype to container-load delivery. Start with an OEM sample and scale to container-load branded production.
Every wind-rated door is built to your opening and your wind zone. Send the clear opening size, the design wind pressure or site exposure (or site photos) and our engineers return a proposal, technical confirmation and lead time.
From custom engineering to container-load delivery — the document set your local installers need.
Warranty: door body 2 years · operator/motor 3 years · servo motor 5 years. Free spare parts within warranty (DHL/FedEx 5–7 days). Lead time: sample 7–15 days · standard container 12–20 days · custom first order 20–35 days.
Wind load resistance for industrial doors is classified on the harmonized EN 12424 scale, which runs from Class 0 (no wind performance declared) up to Class 5 (the highest, above roughly 1,000 Pa). The class is determined by testing the door under positive and negative pressure. RAX markets “Wind Load Class 5 Certified” capability, and the specific class for your door is confirmed per project on the matching EN 12424 test data.
They are different scales and should not be confused. EN 12424 is the harmonized European wind classification for industrial doors, running Class 0–5. RAX’s “Class 12” is a separate proprietary scale used for its spiral high speed doors, on which peer soft-curtain doors typically rate 8–10. A Class 12 spiral door is not the same thing as an EN 12424 Class 5 door. This page uses the EN 12424 scale, confirmed per project.
Three things: a reinforced curtain or stiffened panel that resists deflection; deep, stiffened guide channels that keep the edges captured when the door bows under pressure; and full-perimeter compression seals that stay closed under load. A standard door deflects, the curtain pulls out of the guides, and the seals open — letting in rain and dust. The wind-rated build keeps its rating across the whole opening.
Yes. Every door is engineered to your clear opening width and height, or from site photos. Every door is built to your non-standard size, in any RAL colour. Our engineers confirm the feasible span and the achievable wind class and produce a technical proposal for approval before production.
RAX holds ISO 9001:2015, CE marking against EN 13241 (industrial door product standard) and EN 12453 (operator safety), plus SGS material reports and Product Liability Insurance. The EN 12424 wind class and AS/NZS 4505 / UL counterpart test data are arranged per project, not held as standing certificates.
Sample orders run 7–15 days, a standard container 12–20 days, and a custom first order 20–35 days (repeat custom orders 15–20 days). FOB ports are Tianjin and Qingdao; FCL and LCL are both supported.
Every order includes wiring diagrams, an English installation manual, FAI first-article confirmation and pre-assembly photos, a factory inspection report (speed, noise, insulation resistance, visual), the 100,000-cycle fatigue test video/report, and the CE Declaration of Conformity with the EN 13241 test report.
Send your opening size (W × H), the design wind pressure or site exposure and the target EN 12424 class. Our engineers reply with a proposal and lead time — no obligation.
