02 · Why RAX

A Door Factory, Not a Trading Company

Since 1999, our 60+ engineers have fabricated, assembled and tested every door in-house: a 11,000 m² base, an auto PU foam panel line, CNC punching/bending and a 100,000-cycle fatigue lab – zero outsourcing.

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

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. Across 5,000+ overseas projects we hold a 27-year zero-leak record – 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, FCL and LCL.
