10 Top Window and Door Manufacturers in China: A 2026 Overview

Finding the right partner among Chinese window and door manufacturers takes more than comparing catalogs. Product ranges, customization options, and project capabilities vary widely, and the right fit may differ across dealer networks, hotel projects, and residential developments. This overview highlights 10 top window and door manufacturers in China, providing distributors, builders, and developers with a clearer starting point for an initial supplier shortlist.

What Defines the Top Window and Door Manufacturers?

The top window and door manufacturers are not defined by one product category or marketing claim. This overview uses six practical criteria that matter to project buyers:

• Product range and specialization: Clear expertise in the required window, door, sunroom, facade, or entry-door categories.
• Customization capability: Support for project-specific sizes, glass, finishes, hardware, screens, and opening configurations.
• Residential and commercial suitability: Products and service processes that fit the intended building type and application.
• Technical and export support: Drawing communication, specification coordination, export packaging, and shipping support.
• Product-specific documentation: Test reports and certification or approval records connected to the relevant product system.
• Verifiable official information: Accessible product pages, technical materials, and company information that buyers can review.

Together, these factors indicate whether a manufacturer has the product depth and project support needed for serious consideration.

Quick Snapshot

ZEKIN

ZEKIN serves distributors, builders, contractors, and developers sourcing custom aluminum windows, aluminum doors, and front entry doors for hospitality, residential, and commercial projects. Its range spans multiple opening styles, allowing window, door, and entry packages to be coordinated around one project brief.

• Flexible ordering and customization: ZEKIN accepts project-specific sizes, glazing, colors, finishes, hardware, screens, and opening configurations. It also accepts orders without a minimum quantity, giving buyers greater flexibility for samples, pilot orders, and phased purchasing.
• Project and delivery support: The team assists with drawings, production scheduling, export packaging, and shipping coordination. Its published standard production lead time is 30–35 days, while the confirmed schedule reflects the order volume and specifications.
• Market documentation: ZEKIN provides market-specific compliance documentation for applicable product series, including CE, AS 2047, CSA, NFRC records, and NOA approvals.

For project buyers, these capabilities support sample review, project-based pricing, coordinated technical communication, and export delivery through a single manufacturer.

PHONPA

PHONPA focuses on coordinated residential window and door systems. Its portfolio is relevant to dealer programs and home-improvement projects that require a consistent design approach across exterior openings.

G&C FUSON

G&C FUSON offers a wider architectural catalog than a window-only manufacturer, including specialty window types, entry and garage doors, sunrooms, and narrow-side curtain walls. This breadth is useful for buyers consolidating several exterior-opening categories within one project.

PAIYA

PAIYA focuses on whole-house residential openings, with product lines extending into entrance doors, shower-room systems, sunrooms, and facade-related products. Its positioning is strongest for dealer networks and residential developers seeking coordinated design across several opening categories.

Doorwin

Doorwin emphasizes custom fenestration and specialty shapes. Its material and configuration options suit bespoke homes and light-commercial designs that require nonstandard openings or project-specific specifications.

DERCHI

DERCHI organizes its offering around inward- and outward-opening windows, picture and sliding windows, hinge, sliding, and bifold doors, plus sunrooms. Design and installation resources make it relevant to residential projects requiring coordinated technical input.

Bucalu

Bucalu offers a system-based window and door portfolio, with slim-frame, lift-slide, panoramic, entrance-door, and sunroom series. The portfolio is aimed at architect-led residential and commercial work where frame appearance, opening scale, and system integration shape product selection.

WANJIA

WANJIA operates across both aluminum and uPVC, supported by product lines for curtain walls and sunrooms. This material range is useful for export buyers managing different specifications, climate requirements, or budget levels across one development.

OPPEIN

OPPEIN is a whole-house furnishing company rather than a window-and-door specialist. Its aluminum window and door line is most relevant to developers seeking to procure openings alongside kitchens, wardrobes, bathrooms, interior doors, and other furnishing packages.

SUNHOHI

SUNHOHI is primarily positioned for China’s residential and dealer channels, with system windows and doors as the core of a wider whole-house range that also includes sunrooms, curtain walls, entry doors, and shower doors.

Viewed together, these 10 top window and door manufacturers show the range of product specializations and project capabilities available in China. Their differences become most meaningful when considered against a clearly defined project brief.

How to Choose the Right Window and Door Manufacturer

The right window and door manufacturer is one whose products, customization capabilities, technical documentation, and delivery support match the project’s design, performance, budget, and schedule requirements. A practical assessment of that fit should cover the following areas:

• Confirm complete specifications: Review frame profiles, glass, hardware, finishes, screens, accessories, and opening configurations rather than relying on a general product name.
• Align drawings and technical support: Confirm how project-specific drawings and shop drawings are prepared, how dimensions are checked, and how design revisions are recorded before production.
• Check product-specific reports: When reviewing aluminum window manufacturers, match test reports and applicable certification records to the quoted product system and destination market. For U.S. energy-performance records, the NFRC Certified Products Directory provides a useful reference.
• Define logistics and responsibilities: Confirm packaging, shipping terms, delivery schedules, and the manufacturer’s responsibilities before and during shipment.
• Compare total project value: The best window manufacturers provide complete specifications and useful project support rather than competing on unit price alone.

Clear documentation of these points gives buyers a stronger basis for selection and helps prevent specification, scheduling, or responsibility gaps after approval.
