Serving as the essential grip for furniture, handles facilitate the opening and closing of cabinet doors and drawers while providing decorative enhancement.

• Concealed handles prevent bumps and knocks, making them ideal for families with children
• Handles crafted from aluminum alloy, stainless steel, and other premium materials complement various home styles including modern minimalist, light luxury, and traditional Chinese designs

Optimal handfeel, durability, and appearance are equally essential for premium furniture hardware.

Inferior quality handles are prone to rust, paint peeling, and breakage, which compromise functionality and diminish furniture quality. Our high-quality handles feature refined surface treatments, comfortable handfeel, rust resistance, and exceptional wear resistance—ensuring convenient operation while enhancing overall home interior aesthetics.

• Aluminum alloy grades: Europe (preferred): EN AW-6082-T6 (high strength), EN AW-5052 (high corrosion resistance); North America (common): 6061-T6, balanced strength and machinability
• Anodizing: Complies with ISO 7599, coating thickness grades (AA10/AA15/AA20), sealing quality verified by acid immersion test
• Salt spray test: Neutral Salt Spray (NSS) ≥ 240 h (AA15 coating); Colored anodizing ≥ 168 h, grade ≥ 9; High-end European projects require > 500 h

• Mechanical properties: Tensile strength ≥ 300 MPa, operating torque ≤ 2.8 N*m (accessible design)
• Safety design: No sharp edges (R ≥ 3 mm); rounded and recessed styles preferred for children's rooms to avoid collisions and snags
• Installation tolerance: For European frameless cabinets, installation error ≤ ±0.5 mm to ensure door alignment and smooth operation

• Core advantages: Density only 1/3 that of steel, tensile strength 300-500 MPa (e.g., EN AW-6082-T6), excellent salt spray resistance after anodizing. Suitable for kitchens, bathrooms, marine climates and public spaces
• Surface finishes: Anodizing (natural/black, 10-20 μm), powder coating, PVD coating (hardness HV1200+), meeting aesthetic and durability demands in different regions
• Typical applications: Europe: Recessed long handles; North America: Exposed minimalist linear handles; Asia-Pacific: Customized profiled handles for whole-house custom market
