Built to Your Specifications
Send architectural drawings, a BOQ or just opening sizes. Our engineers select the profile series, glass and hardware, then issue shop drawings for your approval before production starts.
Crestor Door Manufacturing Co., Ltd. designs and builds complete thermal break aluminum window and door systems for distributors, window brands, contractors and developers. Profile machining, powder coating, insulating glass processing and final assembly all happen in our own facilities — so one team is accountable for quality from raw extrusion to the crate that arrives on your site.
Our R&D center is in Beijing and our smart manufacturing base is in Dongying, Shandong. Every system is tested at China's national window test centers, and full reports are shared with buyers who need to verify performance before specifying.
Four commitments that reduce your sourcing risk on every custom window and door order.
Send architectural drawings, a BOQ or just opening sizes. Our engineers select the profile series, glass and hardware, then issue shop drawings for your approval before production starts.
Order corner samples or a full-size sample window first. Check finish, hardware, sealing and build quality in your own hands before committing to a bulk order.
Low-E, argon-filled and laminated insulating glass, thermal break profiles with PA66 strips and matched hardware — in the color and finish your project calls for.
Every unit gets corner guards and film wrap, and is loaded to prevent movement at sea. We ship to the USA, Europe, the Middle East, Central Asia and Australia.
High-performance systems engineered with quality materials and precision manufacturing for residential, commercial and architectural projects — each available in custom sizes, glazing and finishes.
Certified By & Tested With
We started in 1997 as a precision aluminum processor in Beijing. Nearly three decades later, Crestor Door Manufacturing Co., Ltd. designs and builds complete thermal break window and door systems — combining the engineering depth of a system brand with factory-direct pricing.
Because every critical process runs in-house, we control quality at each stage and can build to the sizes, colors and performance levels your project requires. Our team supports OEM brands, distributors, contractors and homeowners across five continents.
Factory tour: profile machining, coating, glass processing and assembly lines.
Six reasons importers, distributors and contractors keep specifying our windows and doors.

Machining, coating, glass processing and assembly under one roof in our 100,000 m² Dongying factory. No middlemen, no subcontracted surprises — one team responsible for quality.

Shop drawings, profile and glass selection, and a digital production system that tracks every order from drawing approval to container loading — so you always know where your project stands.

Tested at China's national window test centers to the top classes of GB/T 31433: wind load, water tightness, air tightness and thermal insulation — plus sound insulation up to Rw 44 dB.

AS 2047 StandardsMark™ Licence (SMK41686) for our 76M tilt & turn system and ISO 9001:2015 quality management. Complete test reports are available on request for your compliance review.

CNC machining to ±0.05 mm, a 12 mm sash overlap and a three-seal design deliver tight, consistent joints on every window — the detail that separates quiet, draft-free windows from callbacks.

Your brand, your colors, your packaging. We supply OEM/ODM windows and doors for distributors and window brands that want reliable capacity without building a factory.
Results from China's national window test centers, graded under GB/T 31433 — translated into practical guidance for specifiers.
| Property | Tested Result | Grade | What It Means for Your Project |
|---|---|---|---|
| Wind Load Resistance | 5.0 kPa | Grade 9 · Top class | Suitable for high-rise façades and exposed coastal sites where profiles and glass must be sized to floor-by-floor wind pressure. |
| Water Tightness | 700 Pa | Grade 6 · Top class | Resists wind-driven rain in storm-prone regions, reducing leak-related warranty claims. |
| Air Tightness | Grade 8 | Top class | Minimizes drafts and air leakage — essential for energy-code compliance and HVAC efficiency. |
| Thermal Insulation (Whole Window) | U ≤ 0.9 W/m²K | Grade 10 · Top class | Supports passive-house-level envelopes and cold-climate energy targets when paired with Low-E, argon-filled IGUs. |
| Sound Insulation | Up to Rw 44 dB | Acoustic | Ideal for hotels, city apartments and properties near roads, rail or airports. |
Values reflect tested configurations; actual performance depends on system series, size and glass build-up. Full test reports are available on request — see our Quality Assurance process.
