Gate hinges are mechanical devices that allow gates to swing open and closed. They are typically made of metal or heavy-duty plastic and come in various sizes and styles to accommodate different types of gates. Proper installation of gate hinges ensures smooth operation and durability. These hinges are designed to support the weight of the gate while providing stability and security. Some common types include butt hinges, piano hinges, and strap hinges. Choosing the right type of hinge is essential for the functionality and longevity of the gate, especially in outdoor settings where weather conditions can affect performance.
