Guangzhou Cresta Door & Window Co., Ltd. stands as a beacon of precision structural engineering and modern fenestration technology. Established in 2015, Cresta operates a state-of-the-art 18,000-square-meter manufacturing facility engineered specifically for high-capacity, high-precision custom production. Grounded in 11 years of deep industry expertise and 7 years of seamless international trade operations, our infrastructure yields an annual export turnover of $22 million across critical global markets including Southeast Asia, the Middle East, North America, and Oceania.
We serve as the primary manufacturing partner for custom home builders, structural renovation contractors, and major regional building materials wholesalers. Our continuous investment in advanced manufacturing tech, quality control loops, and upstream supply integration enables us to deliver commercial and residential aluminum doors with integrated window systems that exceed structural, thermal, and acoustic performance thresholds.
To guarantee flawless execution, our team of 30 dedicated Quality Control (QC) inspectors enforces ISO-certified optical surface inspections, precision laser dimensional profiling, and pressurized weatherproofing seal tests. Supported by a robust network of 550 upstream material suppliers, Cresta excels in engineered-to-order solutions, including multi-chamber acoustic insulation, motorized hidden insect screens, and structural ultra-slim frame sliding wall systems. Driven by an inventive engineering culture, our R&D division launched 38 newly patented product series within the past fiscal year alone.
Our aluminum doors with integrated windows utilize high-grade 6063-T5 and T6 primary aluminum billets. Yielding tensile strength up to 230 MPa, these profiles deliver superior wind load resistance (up to 5.0 kPa) while maintaining minimal frame sightlines. Surface treatments include fluorocarbon (PVDF) coating, electro-anodizing, and hyper-durable powder coatings resistant to salt spray corrosion for coastal installations.
To eliminate the natural conductivity of metal frames, we integrate Technoform PA66 GF25 (25% glass fiber reinforced polyamide) thermal barrier strips. By decoupling inner and outer aluminum extrusions, the overall U-factor is driven down to as low as 1.2 W/m²K (U-0.21 BTU/hr·ft²·°F), drastically cutting HVAC energy demands in both tropical heat and freezing sub-zero environments.
System configurations support double and triple-glazed Low-E insulated glass units (IGUs) filled with 90% Argon gas. Utilizing structural silicone glazing (SSG) alongside triple-sealed continuous EPDM weatherstripping gaskets, our integrated door-window units achieve acoustic attenuation ratings up to STC 45 dB, keeping high-noise urban environments dead silent.
Certified under AS2047 for structural deflection, air infiltration, water penetration resistance, and ultimate strength tests. Compliant with AS1288 human impact safety glass requirements for residential and high-rise commercial structures.
Engineered for NFRC thermal performance indexing (SHGC, U-factor, Visible Transmittance). Tested for Florida High-Velocity Hurricane Zones (HVHZ) under large missile impact resistance protocols to protect coastal properties against extreme storms.
Full compliance with CE marking guidelines under EN 14351-1 for exterior pedestrian doorsets and windows. ISO 9001 quality system management guarantees traceably consistent manufacturing batches.
Operating directly out of Guangzhou—the heart of South China’s premier industrial manufacturing cluster—Cresta leverages unparalleled supply chain density. With over 550 upstream suppliers for hardware, sealants, specialty glass, and extruded aluminum profiles within a 50-kilometer radius, we shorten manufacturing lead times by up to 35% compared to regional competitors.
In hurricane-prone coastal sectors (such as Florida, the Caribbean, and coastal Australia), standard door-window combinations fail under extreme wind loads and salt air corrosion. Cresta's heavy-duty reinforced entry and folding door systems feature structural steel inner mullions, continuous heavy-gauge hinges, and laminated impact glass that withstand severe cyclic pressure while remaining effortless to operate.
City living demands maximum indoor daylighting coupled with acoustic isolation. Our ultra-slim profile aluminum doors with integrated transom windows maximize overall transparent surface areas. Enhanced by double-glazed argon IGUs, these assemblies suppress street traffic sound by up to 45 decibels, creating peaceful indoor sanctuaries.
For restaurants, hotels, and retail complexes, smooth transitions between indoor spaces and outdoor patios are critical. Our NFRC-certified bi-fold glass walls and lift-and-slide doors provide barrier-free flush thresholds compliant with ADA mobility guidelines, complete with motorized integrated blinds for instant shade control.
We work directly with regional wholesalers and large-scale developers to deliver fully custom extrusion colors (RAL palette matching), motorized insect screens, multi-point lock hardware integrations (German Hoppe/CMECH), and pre-assembled knocking-down (KD) packaging to optimize sea-freight container load density.
Architectural demand has shifted heavily toward ultra-narrow interlocks (as thin as 20mm visible width). Our R&D team utilizes high-tensile 6063-T6 extrusions to support massive floor-to-ceiling glass panels without compromising structural load ratings.
Integration of automated concealed motors compatible with smart home ecosystems (Zigbee/KNX). Doors and integrated transom windows automatically adjust based on indoor air quality, rain sensors, or smartphone automation.
Aluminum boasts a 100% recycling capability without material degradation. Cresta utilizes eco-conscious low-carbon primary aluminum billets alongside non-toxic, solvent-free powder coatings, assisting projects in obtaining LEED v4 certifications.
