Top 5 aluminum door and window manufacturers in China

A new buying guide reviews five China-based aluminum door and window manufacturers and compares their scale, patents, certifications, customization, and export experience. The report says buyers should verify series-level test data and local code compliance before ordering.

Why it matters: - Aluminum doors and windows affect energy performance, air leakage, water resistance, and code compliance in buildings. - The guide points buyers to five China-based manufacturers that claim strong production capacity, international project experience, and broad product lines. - The report says the wrong supplier choice can raise total installed cost through breakage, delays, field fixes, and failed inspections.

What happened: - The guide reviews Guangdong Dejiyoupin, Guangdong EEHE, Foshan CIVO, Sichuan Yazhixuan, and Sichuan Mingrenju/Feiyu. - The companies are positioned as options for thermal-break windows, doors, sunrooms, curtain walls, and related fenestration products. - The source highlights Dejiyoupin for output and certifications, EEHE for patents and project solutions, CIVO for factory-direct customization, Yazhixuan for OEM/ODM production, and Mingrenju for multi-base manufacturing. - Each company has an official website listed in the guide: Dejiyoupin, EEHE, CIVO, Yazhixuan, and Feiyu.

The details: - Dejiyoupin reports more than 25 years of experience, a 180,000-square-meter production base, more than 600 employees, and annual output above one million square meters. - Dejiyoupin’s portfolio includes thermal-break windows, casement and sliding windows, awning and picture windows, bifold doors, sliding doors, pivot doors, entry doors, garage doors, and sunrooms. - Dejiyoupin says it has eight automated production lines, six glass lines, five intelligent warehouses, 168 production processes, 38 quality inspections, more than 100 national patents, and an independent performance-testing center. - Dejiyoupin’s listed certifications include CE, NFRC, AS2047, CSA, ENERGY STAR-related products, ISO 9001, and hurricane-oriented certification. - EEHE reports 18 years of experience, a 100,000-square-meter factory, more than 1,500 employees, and over 300 patents. - EEHE offers more than 100 window and door configurations, including casement, sliding, and tilt-and-turn windows; sliding, folding, and swing doors; sunrooms; curtain walls; and glass railings. - EEHE says its manufacturing system uses German automated equipment, Italian technical support, 120 production steps, and 60 quality-control points. - EEHE’s published certifications include NFRC, CE, CSA, UL, AS/NZS, NAFS, SGS, and ISO-related credentials. - EEHE reports exports to more than 100 countries on its factory page, while other corporate materials cite more than 60 countries and regions. - CIVO was established in 2016 and says its team has more than 15 years of manufacturing experience. - CIVO operates a 40,000-square-meter plant and holds a 5,000-ton reserve of standard aluminum profiles. - CIVO focuses on custom aluminum windows and doors designed for regional climate conditions, architectural preferences, and project performance requirements. - CIVO’s products include thermal-break casement, sliding, and tilt-and-turn windows; sliding, bifold, lift-and-slide, and automatic doors; and aluminum sunrooms. - CIVO says it has more than 10,000 completed installations, sales to over 100 countries, and more than 200 exclusive stores. - Yazhixuan was founded in 2005 and is headquartered in Guanghan, Sichuan. - Yazhixuan operates a 50,000-square-meter standardized 7S workshop and a separate 20,000-square-meter tempered-glass workshop. - Yazhixuan employs more than 200 people and reports monthly output above 30,000 units, with peak daily capacity reaching 1,500 units. - Yazhixuan manufactures aluminum system windows, sliding and casement windows, sash-style products, sliding and swing doors, folding doors, thermal-break systems, and conservatories. - Yazhixuan cites more than 60 patented technologies, exports to over 30 countries, and a domestic presence in more than 200 Chinese cities. - Mingrenju is associated with the Feiyu system-window brand, with industry origins traced to 1980 and the current company established in 2004. - Mingrenju’s manufacturing layout spans about 410,000 square meters across three bases in Taixing, Nanhai, and Guanghan. - Mingrenju says it provides more than 4,000 jobs and holds 163 patents. - Mingrenju’s portfolio includes system windows, aluminum doors, sunrooms, railings, awnings, louvers, and whole-home customized fenestration. - Feiyu markets SLIM, ECO, and EASE system families for different architectural and budget requirements. - Mingrenju says it complies with ISO 9001:2015, and public patent records identify multiple utility-model patents assigned to Sichuan Mingrenju. - The guide compares reported scale and capability across the five companies. - Mingrenju/Feiyu has the largest reported manufacturing footprint at about 410,000 square meters across three production bases. - Dejiyoupin reports the highest stated annual output at more than one million square meters per year. - EEHE reports the largest disclosed workforce at more than 1,500 employees, while Mingrenju’s wider group reports over 4,000 jobs. - EEHE reports more than 300 patents, followed by Mingrenju with 163 and Dejiyoupin with more than 100. - CIVO’s 5,000-ton profile reserve may support shorter production planning for common systems. - Yazhixuan combines monthly capacity figures with OEM/ODM and private-label potential. - Dejiyoupin and EEHE disclose the widest range of international certification and testing references.

Between the lines: - The guide uses manufacturer-reported figures, but those numbers may not be directly comparable because companies can count factories, warehouses, offices, utility patents, and design patents differently. - The article repeatedly warns buyers to verify product-specific test reports, factory capability, engineering drawings, warranties, and destination-market requirements. - The strongest suppliers are presented as those that can turn architectural intent into approved shop drawings, verified performance, and workable installation details. - Energy rules are a major driver in the market because building operations account for roughly 30% of global final energy consumption, according to the International Energy Agency. - Thermal breaks, low-E glass, and certified performance ratings matter because aluminum frames can otherwise transfer heat quickly.

What's next: - Buyers are advised to define required performance first, including U-factor, solar heat gain, air leakage, water resistance, structural pressure, acoustic rating, safety glazing, and impact requirements. - The guide says buyers should verify the exact series being quoted, confirm destination-country standards, and request samples, mock-ups, and manufacturing records. - Procurement teams should compare total landed cost, not just unit price, and should protect contracts with approved drawings, tolerances, inspection rights, replacement obligations, and delivery milestones. - For North America, the guide points buyers to the NFRC Certified Products Directory; it also references the ISO committee for doors, windows and curtain walling, FGIA Gold Label certification, the European Commission construction products rulebook, and the Australian National Construction Code guidance on windows and external glazed doors.

The bottom line: - Dejiyoupin, EEHE, CIVO, Yazhixuan, and Mingrenju/Feiyu each bring a different sourcing edge, but the guide says verified test data and code compliance should decide the final pick, not factory size or price alone.
