Key Selection Factors
-
Load Capacity: Ball bearing hinges handle >100kg, while thin flush hinges suit <20kg.
-
Environment: Marine hinges use 316 stainless steel; indoor decorative hinges may prioritize aesthetics.
-
Movement Range: Pivot hinges allow 360° rotation; standard butt hinges typically 90-180°.
-
Security: Lift-off hinges deter forced entry; concealed hinges improve tamper resistance.
