UsionTop launches the cold-rolled steel4D Hinge onOctober28, 2025. This high-quality hardware, available in natural, gunmetal gray and titanium alloy finishes, solves door-closing stability and aesthetic matching pain points for furniture manufacturers, ensuring smooth three-section force control and long service life via high-quality cold-rolled steel.

Key Features/Benefits

Three-Section Force Control + Stable Closing Experience

The hinge features professional three-section force design: the first section (0-45°) with light force for easy opening, the second section (45-120°) with stable positioning to prevent sudden closing, and the third section (120-180°) with buffer closing to avoid collision noise. For cabinet factories producing kitchen cabinets and wardrobe, it prevents cabinet doors from slamming and protects glass door panels from breaking.

High-Quality Cold-Rolled Steel + Data-Validated Durability

Adopting 1.2mm thick cold-rolled steel with electrophoretic coating, the hinge’s tensile strength reaches 500MPa, 25% higher than ordinary carbon steel hinges. It passes 80,000 opening-closing cycles without loosening and bears 40kg static load for 24 hours without bending or deformation.

Three Color Options + Aesthetic & Scenario Adaptation

Providing three finishes: natural (matte silver) matches modern minimalist furniture, gunmetal gray fits industrial style and dark wood furniture, and titanium alloy (simulated titanium texture) complements high-end luxury furniture. The coating adheres firmly, passing 500-hour wear resistance test without fading, meeting diverse aesthetic needs of furniture brands.
