I. Door & Window Hinges: International Mainstream Applications & Selection

1. Core Application Scenarios (Global Universal)

• Aluminum alloy door & window hinges: Standard configuration for mainstream door & window systems in Europe, North America, and Southeast Asia. Used for fixing hinge leaves to profiles and bases, ensuring smooth opening/closing and long-term fatigue resistance.
• UPVC door & window hinges: Suitable for connecting dissimilar materials (plastic profiles + metal hinges), avoiding welding damage to base materials.
• Heavy-duty / fire door hinges: For high-load-bearing and high-safety applications, high-strength structural rivets are selected.
• Hinge repair & renovation: For worn hinge holes, drive-in expansion rivets enable quick repair without reaming.

2. International Common Rivet Types (According to Standards)

3. Materials & Surface Treatments (International Mainstream)

• Aluminum alloy (5056/6061): Lightweight, corrosion-resistant, suitable for aluminum alloy doors & windows; mainstream in Europe and Southeast Asia.
• Stainless steel (304/316): 304 for general use; 316 for salt spray resistance, ideal for coastal / humid regions (e.g., Australia, Northern Europe).
• Carbon steel (Q235/10B21): High strength, low cost, commonly used for indoor doors & windows; requires galvanizing / Dacromet for rust prevention.
• Copper alloy (H62): For decorative hinges, retro doors & windows, aesthetic and corrosion-resistant.

4. International Application Characteristics

• Assembly efficiency: Pneumatic / electric riveting, 0.5–2 seconds per piece, suitable for door & window assembly lines; widely adopted by European and American factories.
• Reliability: No loosening under 2 million vibrations, meeting door & window opening/closing life requirements (≥100,000 cycles).
• Appearance: Countersunk / round head design, smooth and protrusion-free after riveting, in line with high-end door & window aesthetics.
• Standardization: Globally applicable ISO, DIN, ASME standards, facilitating cross-border procurement and assembly.
