Explore our certified commercial-grade double doors, bi-fold systems, and architectural structural glass solutions designed for severe weather resilience and energy efficiency.
A global leader in OEM architectural fenestration, custom aluminum extrusion processing, and high-performance double door manufacturing.
Established in 2015, Guangzhou Cresta Door & Window Co., Ltd. operates a 18,000-square-meter manufacturing facility. Backed by 11 years of industry experience and 7 years of international trade operations, we achieve an annual export turnover of $22 million across Southeast Asia, the Middle East, and Oceania. We mainly supply custom home builders, renovation contractors, and regional wholesalers.
To ensure top-tier craftsmanship, our team of 30 QC inspectors strictly enforces ISO-certified optical surface inspections and weatherproofing seal tests. With a reliable network of 550 upstream suppliers, Cresta excels in tailored solutions such as custom acoustic insulation, motorized insect screens, and slim-frame sliding doors. Supported by an active R&D division of 35 specialized engineers, we released 38 new product series over the past year.
A deep technical analysis into metal alloy composition, structural thermal break integration, acoustic performance, and hardware load capacity.
We utilize primary 6063-T6 architectural grade aluminum extrusions with a minimum wall thickness of 2.0mm to 3.0mm for load-bearing double door profiles. Tensile strength exceeds 205 MPa, delivering superior structural stability against wind loads and heavy structural cycling.
Engineered with 25% glass fiber reinforced Polyamide (PA66GF25) thermal barrier strips. This multi-cavity thermal break system effectively eliminates thermal bridging, lowering total frame U-values down to 1.4 W/m²K and preventing interior condensation in harsh climates.
Double and triple glazed IGUs feature Argon gas filling, Low-E thermal coatings, and SGP/PVB laminated impact interlayers. Standard configurations deliver acoustic reduction up to STC 42dB and hurricane wind load resistance up to +/- 90 PSF under Florida NOA guidelines.
