Crestor Door Manufacturing Co., Ltd. is a premier OEM/ODM manufacturer specializing in high-performance thermal break aluminum window and door systems. Founded in 1997, our enterprise integrates R&D, structural engineering, precision extrusion, surface treatment, insulated glass unit (IGU) processing, and automated final assembly.
Operating across two dedicated manufacturing hubs—our R&D and custom export engineering facility in Beijing and our 100,000 m² smart manufacturing base in Dongying, Shandong—we deliver complete fenestration solutions tailored to international building codes, structural wind loads, and thermal compliance standards across 30+ countries.
Our engineered systems undergo rigorous third-party verification at national window testing centers. Crestor Door Manufacturing Co., Ltd. holds AS 2047 StandardsMark™ certification (Licence SMK41686), ISO 9001:2015 quality management accreditation, CE conformity for European markets, and structural compliance ratings for NFRC and AAMA projects.
Combining complete vertical supply chain integration with certified structural performance for global B2B projects.
Our dual-facility strategy provides immense scalable output and customized engineering agility. Our Beijing R&D center oversees structural design and export management, while our 100,000 m² Shandong facility executes high-capacity extrusion, powder coating, and automated assembly.
Moving beyond standard mechanical corner joinery, Crestor Door Manufacturing Co., Ltd. utilizes automated laser seamless cold-welding. Corner joints are structurally fused into a solid frame, eliminating air infiltration, water leakage, and frame sagging under intense structural loads.
Engineered with PA66 GF25 polyamide thermal break strips (24mm–50mm) and automated Low-E double/triple argon-filled insulating glass, our fenestration systems achieve thermal values as low as U ≤ 0.9 W/m²K, meeting modern Passive House and green building codes.
We source exclusively from top international hardware and material suppliers: Italian GIESSE, German HOPPE and WINKHAUS hardware, German TIGER and AkzoNobel powder coatings, Ensinger thermal breaks, and CSG automotive-grade float glass.
Tested under strict GB/T 31433 and international standards, our window systems demonstrate 5.0 kPa wind load resistance (Grade 9), 700 Pa water tightness (Grade 6), Grade 8 air tightness, and acoustic attenuation up to Rw 44 dB.
We deliver end-to-end custom engineering for private label brands, distributors, and general contractors—from custom die profile extrusion and structural CAD shop drawings to over 300 RAL architectural powder coatings.
Complete control over raw profile extrusion, machining, surface finishing, and glass processing ensures rigorous quality standards.
In-house 6063-T5 architectural aluminum extrusion lines providing high structural integrity and tight wall tolerances.
High-precision 5-axis CNC machining centers and robotic arms achieving ±0.05 mm fabrication accuracy.
Swiss Gema vertical powder coating lines providing weather-resistant PVDF, anodized, and wood-grain thermal transfers.
Automated double/triple Low-E glazing, warm-edge TPS spacer insertion, and automated argon gas filling lines.
Every order undergoes rigorous internal inspection to guarantee flawless field performance upon delivery.
Spectrometric alloy analysis for 6063-T5 aluminum, coating adhesion testing, gasket elasticity checks, and float glass clarity verification before entering production.
Laser-guided corner angle checks, CNC dimensional calibration, thermal strip shear-strength testing, and continuous seal alignment inspections at every assembly station.
System testing for wind load resistance, air permeability, water tightness, hardware operation durability, and export crate protective packaging verification.
