Pure Copper Hardware System
Equipped with PURE COPPER DOUBLE-POINT LINKAGE HARDWARE (custom-developed system).
Solid copper material provides strong corrosion resistance and long-term durability.
The double-point linkage structure ensures stable locking and smooth operation.
Precision mechanical design improves reliability and overall user experience.
This hardware system is specially developed for French-style windows, combining performance with a premium architectural appearance.
French Grille Design
The system offers two grille options to match different French-style aesthetics:
Flat grille features a clean and simple profile, recommended for interior use due to better safety and ease of maintenance.
Closed-edge grille has a more dimensional shape with stronger visual depth, delivering a more authentic French architectural look. It is more suitable for exterior applications.
Both options allow flexible design according to project style and usage needs.
Optional 304 Stainless Steel Insect Screen
To improve comfort and ventilation, our windows can be equipped with durable insect screens made from 304 stainless steel mesh. This material provides excellent corrosion resistance and long-lasting performance.
The insect screen system can be customized according to the window opening style, including:
Outward opening windows
Inward opening windows
Sliding window systems
This flexible configuration allows fresh air circulation while effectively preventing insects from entering indoor spaces.

FAQS
What markets is this window system suitable for?
Our H1 French-style casement window is designed for global applications across different climate zones.
We provide matched glazing solutions:
Single glass for Southeast Asia (ventilation-focused)
Double glazing for Europe (thermal & acoustic balance)
Triple glazing for North America (high insulation & cold resistance)
We can also recommend the best configuration based on your specific project location.
Can the window meet local building codes and certifications?
Yes. Our window system complies with major international standards, including:
CE (Europe)
AS/NZS2047 (Australia)
NFRC (North America)
For project-based requirements, we can provide test reports, technical documents, and support for compliance submission.
What is the typical lead time for bulk orders?
Our standard production lead time is 25–30 days, depending on order size and customization level.
For large projects, we can arrange phased production and delivery schedules to match your construction timeline.
How does the thermal break aluminum system boost overall window performance?
All our thermal break aluminum windows adopt PA66 glass fiber reinforced insulated strips, which effectively separate inner and outer aluminum frames and reduce heat conduction.
Combined with a multi-cavity profile structure, vertical isotherm design, EPDM sealing system, and insulated glass units, the system delivers excellent performance in:
Thermal insulation
Cold resistance
Sound insulation
Airtightness and waterproofing
It fully meets modern energy-saving building standards and is suitable for extreme climate environments.
What is the appearance advantage of the H1 French retro aluminum window?
The H1 model features an ultra-slim visible frame design of approximately 22mm, delivering a refined French retro architectural style.
Compared with standard aluminum windows, it provides a more elegant façade appearance and improved visual proportion for high-end buildings.
We also offer two grille systems:
Built-in hollow grille (durable, low maintenance, anti-aging)
External decorative grille (flexible styling, easy replacement)
Both flat and closed-edge grille designs are available to meet different European architectural preferences.
What is the difference between flat grille and closed-edge grille
Flat grille has a smooth surface and no sharp edges, making it safer for interior use and easier to maintain.
Closed-edge grille has a raised profile with stronger visual depth, creating a more traditional French appearance.
For practical use, flat grille is recommended on the interior side, while both options can be used on the exterior depending on design preference.
What makes the hardware system of the H1 French retro window different?
The H1 French retro aluminum window is equipped with a custom-developed PURE COPPER DOUBLE-POINT LINKAGE HARDWARE system, designed specifically for high-end French-style architectural windows.
Unlike standard industrial hardware systems, this pure copper linkage mechanism is engineered as a dedicated solution for H1, focusing on both aesthetic consistency and long-term durability.
Key advantages include:
Solid pure copper construction, offering excellent corrosion resistance and weather durability
Double-point linkage structure, ensuring stable locking performance and smooth operation
Precision mechanical design, improving long-term reliability and reducing wear during frequent use
Architectural-grade appearance, better matching the classic French retro window style
Compared with conventional German VBH hardware systems used in engineering-focused windows (such as H7 series), the H1 pure copper system places greater emphasis on luxury detailing, material authenticity, and architectural aesthetics, making it ideal for premium residential villas, boutique hotels, and heritage-style projects.
Is customization available for projects or brands (OEM/ODM)?
Absolutely. We specialize in OEM & ODM cooperation for contractors, developers, and window brands.
Customization options include:
Frame color & surface finish
Glass type & thickness
Decorative grille design
Hardware configuration
Branded packaging
We also support shop drawings and technical coordination for project orders.
What is the difference between built-in grille and external grille?
Built-in grille: Sealed inside the glass unit, making it waterproof, dustproof, fade-resistant, and maintenance-free. It is ideal for long-term fixed installations.
External grille: Installed on the surface, allowing flexible style changes and easier replacement. It is more suitable for projects requiring decorative flexibility.
Do you provide samples before bulk orders?
Yes, we strongly recommend sample evaluation before bulk purchasing.
Samples allow you to verify:
Material quality
Hardware operation
Surface finishing details
Sample cost and shipping can be arranged based on your project stage.
