02 · Why RAX

Every Door Built In-House, Tested to Last

Since 1999 we have fabricated, assembled and tested every door in-house – factory-direct pricing, direct quality control and one engineer accountable for your project from first drawing to repeat order.

  • Pure manufacturer – every panel, opener and spring part made and tested in one factory, nothing outsourced
  • 100,000-cycle fatigue test lab validates durability before any door is allowed to ship
  • We do not install on site – your local team receives English manuals and wiring diagrams
  • Tested from -30°C cold storage to +50°C desert conditions for global climates

04 · OEM / ODM Process

From Custom Engineering to Container-Load Delivery

Every project gets a dedicated R&D engineer, a physical sample for approval and 100% final inspection. Here is the exact path your doors take.

STEP 01

Inquiry + DFM

Share drawings, sizes or reference photos. Our 20+ R&D engineers return structural suggestions, a Design-for-Manufacturing report and cost targets – before any tooling commitment.

24-48 hrs
STEP 02

technical drawing + Sample

Full technical drawings plus a physical sample for approval. You verify size, material and finish before mass production begins.

7-15 days
STEP 03

FAI Sign-Off

First-article confirmation with pre-assembly photos. You sign off the FAI before the container run – no surprises on the line.

FAI approved
STEP 04

Mass Production

Dedicated production scheduling keeps first orders and repeat runs on schedule, with pre-assembly photos shared before sign-off.

12-20 days / container
STEP 05

100,000-Cycle QC

Speed, noise, insulation resistance and visual inspection on every door, plus a 100,000-cycle fatigue test report.

100% inspected
STEP 06

05 · Compliance & Trust

Certified for Every Market

Compliance is not a checkbox – it is what keeps your goods moving through customs. Our certificates are current, independently audited and shipped with every order.

ISO 9001:2015Quality management system
CE EN 13241Industrial door compliance
CE EN 12453Operator safety compliance
SGSMaterial verification reports
Product Liability InsuranceBacked coverage on file

Certificates and the EN 13241 test report travel with your goods. We can also support AS/NZS 4505 (Australia) and UL (North America) counterpart test data on request. Fire-rated construction (EI60/EI120) is an engineering capability provided per project – not a held certificate.

What is your order flexibility?

Every project is custom-manufactured to your specifications — from small-batch component orders for installers and distributors to full container-load repeat runs. Standard components and door operators are available in small batches, ideal for project-based procurement and service teams that need parts fast.

What are your payment terms?

Standard terms: 30% T/T deposit + 70% against B/L copy. We accept L/C at sight for large projects and OA 30 days for repeat clients. Every shipment includes our inspection report, so you verify quality before the balance is due.

How long is the lead time?

Samples: 7-15 days. Standard container: 12-20 days. Custom first order: 20-35 days, with repeat orders at 15-20 days. Standard production runs at 12 days per container, and tooling is archived for up to 5 years so repeat orders skip the setup wait.

What is your warranty and after-sales policy?

Door body 2 years; operator/motor 3 years; servo motor 5 years. Free spare parts within warranty ship via DHL/FedEx in 5-7 days. Tooling records are archived up to 5 years with no extra tooling fee on repeat orders, and your account manager responds promptly to any issue.

How do you protect my OEM design?

We sign a mutual NDA before any OEM/ODM discussion, and your tooling is archived separately and used only for your orders – your drawings and branding stay confidential from first sample to repeat orders.

Which certifications do your doors carry?

ISO 9001:2015, CE (EN 13241 industrial door + EN 12453 operator safety) and SGS material reports, plus Product Liability Insurance. Certificates and the EN 13241 test report travel with your goods. We can also support AS/NZS 4505 (Australia) and UL (North America) counterpart test data on request. Fire-rated construction (EI60/EI120) is an engineering capability provided per project, not a held certificate.

What documents ship with my order?

Every order ships with a Factory Inspection Report (speed, noise, insulation resistance, visual), a 100,000-cycle fatigue test report, FAI / pre-assembly photos, an English installation manual + technical drawings + wiring diagrams, and a CE Declaration of Conformity with the EN 13241 test report. Export packing uses a steel frame + pearl cotton + stretch film with a traceable batch number; we ship FOB Tianjin or Qingdao, FCL and LCL.

Engineered to Your Exact Specifications.

Send your drawings, sizes or reference photos. Our 20+ R&D engineers respond within 24-48 hours with a DFM proposal, estimated cost and sample timeline. Every door is custom-manufactured to your performance requirements.
