Source Factory · Est. 199925+ years engineering doors for logistics, food processing and manufacturing brands across 50+ countries. Not a trading company — a manufacturer, with a 11,000 m² production base of our own.
RAX Door Technology was founded in 1999 in Cangzhou, Hebei — the heart of China’s industrial-door manufacturing cluster. What began as a focused door workshop has grown into a 11,000 m² production base with 60+ engineers and 20+ R&D engineers.
Today RAX doors operate in 50+ countries across 5,000+ overseas projects — each one engineered, tested and built in-house, never outsourced.
We remain what we have always been: a pure manufacturer. Any size, any spec, custom engineered to your specification — from custom engineering to container-load delivery.
We exist to solve the failures that cost industrial operators money — sealing and insulation below spec, insufficient high-cycle durability, hard-to-source non-standard sizes, and the need for smart, energy-compliant doors. We do it by manufacturing every door, opener and component under one roof, validated from -30°C cold storage to +50°C desert conditions.
Across 11,000 m², we produce doors, openers and spring parts in one factory — the reason our quality is consistent and our lead time is stable.
Continuous 40–50 mm PU insulated panel production for sectional and cold storage doors.
Precision forming of galvanized steel and aluminum components to tight tolerances.
In-house servo VFD drive assembly for smooth, high-frequency door operation.
Every platform validated under rigorous long-cycle fatigue testing protocols.
Our 20+ R&D engineers develop door systems, drives and controls in-house — from servo VFD drive and radar/geomagnetic/light-curtain sensing to WiFi/RS485 remote for Industry 4.0 smart door control.
Durability is not a claim; it is a test result. Our 100,000-cycle fatigue test lab validates every platform before it reaches your facility, backed by SGS-validated galvanized steel and aluminum alloy materials.
“Rigorous 100,000-Cycle Fatigue Testing Protocols, Validated Galvanized Steel & Aluminum Alloy Materials, and Precision Servo-Drive Manufacturing.”
A documented quality system backs every shipment — with internationally recognized certification and traceable test data your inspectors can verify.
Panel lines, CNC forming, servo assembly, testing and export packing — all under one roof in Cangzhou.
5,000+ overseas projects served across every major market. We ship FCL and LCL from FOB Tianjin/Qingdao.
We manufacture; your local team installs. This keeps your project fast, controllable and free of cross-border service complexity. With every order we deliver the complete engineering package your installers need:
We do not send crews to site — and that is by design. You retain full control of installation while we guarantee the engineering behind it.
RAX Door Technology is established in Cangzhou, Hebei — China’s industrial-door cluster — as a dedicated door manufacturer.
Auto PU foam panel line, CNC punching/bending center and servo motor assembly line bring doors, openers and parts under one roof.
An in-house fatigue test lab makes long-cycle durability a verified test result, not a marketing claim.
ISO 9001:2015, CE (EN 13241 / EN 12453), SGS material reports and Product Liability Insurance formalize our quality system.
A 11,000 m² base, 60+ engineers and 20+ R&D engineers serve partners worldwide from Cangzhou.
We are a source factory, founded in 1999. Our 11,000 m² production base, 60+ engineers, 20+ R&D engineers and 100,000-cycle fatigue lab are all our own — we manufacture doors, openers and components in-house and never outsource the core build.
Yes. We welcome qualified buyers to visit our Cangzhou production base. Contact us at info@raxdoor.com to arrange a visit.
We sign NDAs for all OEM/ODM work, archive tooling for up to 5 years with no extra tooling fee for repeat orders, and maintain a 27-year zero-leak record.
No. We are a pure manufacturer. Every order ships with English installation manuals, wiring diagrams so your local team can install confidently without on-site support from us.
Send us your opening size, application and target spec. Our engineers reply with a proposal and technical layout — no obligation.
