Explore our primary export-grade fenestration product series optimized for thermal performance, structural wind resistance, and modern acoustic comfort.
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 $22 million across Southeast Asia, the Middle East, and Oceania. We mainly supply custom home builders, renovation contractors, and regional wholesalers.
To ensure top-tier craftsmanship, our team of 30 QC inspectors strictly enforces ISO-certified optical surface inspections and weatherproofing seal tests. With a reliable network of 550 upstream suppliers, Cresta excels in tailored solutions such as custom acoustic insulation, motorized insect screens, and slim-frame sliding doors. Supported by an active R&D division of 35 specialized engineers, we released 38 new product series over the past year.
The global demand for premium OEM/ODM aluminium folding doors (bi-fold fenestration systems) is experiencing unprecedented growth driven by modern urban architectural standards, strict energy efficiency mandates, and luxury space optimization.
Architects in residential luxury villas and high-end hospitality projects increasingly demand zero-threshold, ultra-wide opening systems. Aluminium bi-fold doors eliminate visual barriers, allowing continuous transitional spaces from interior living rooms to exterior infinity terraces.
International building codes (such as IECC in North America, Title 24 in California, and Part L in the UK) require strictly low thermal transmittance ($U$-values below 1.4 $W/m^2K$). Advanced thermal break polyamide insulation strips within extruded aluminum profiles have become an essential engineering baseline.
Coastal and hurricane-prone geographic regions demand high wind-load ratings (up to 5000 Pa) and forced entry resistance. Importers require validated ASTM impact testing, dual-durometer synthetic rubber gaskets, and heavy-duty stainless steel multi-point gear lock mechanisms.
Guangzhou Cresta Door & Window Co., Ltd. builds structural excellence into every extrusion profile, thermal barrier, and glass configuration.
We utilize prime-grade T6063-T6 architectural aluminum alloy extrusions. This specific temper delivers high tensile strength (minimum 190 MPa) and yield strength (minimum 170 MPa), ensuring structural integrity across expansive multi-panel bi-fold spans without frame sagging or flex deformation.
To eliminate aluminum's natural high thermal conductivity, Cresta integrates 24mm to 34mm PA66GF25 (Polyamide 66 reinforced with 25% glass fiber) thermal barrier strips. This structural setup significantly diminishes thermal bridging, preventing condensation build-up while enhancing energy preservation in extreme freezing or desert climates.
Our insulated glass units (IGU) feature custom tempered Low-E double or triple glazing combinations with argon gas insulation (e.g., 6mm Low-E + 12Ar + 6mm Clear Tempered). Warm-edge composite spacer bars reduce heat transfer at glass edges, achieving sound attenuation ratings up to STC 42 dB.
