Product Introduction
A door hinge is a mechanical device connecting a door to its frame, enabling smooth rotation for opening and closing. Typically made of metal—such as steel, brass, or stainless steel—for durability, it consists of two plates (leaves) joined by a central pin, allowing pivotal movement.
Available in various types, including butt hinges (most common), pivot hinges, and strap hinges, each suits specific needs: butt hinges for standard doors, pivot hinges for heavy or oversized doors, and strap hinges for rustic or decorative styles. Sizes range from small (for cabinets) to large (for industrial doors), with load capacities matching door weight.
Beyond functionality, hinges impact a door’s longevity and performance—quality hinges prevent sagging, reduce noise, and ensure alignment. They’re essential in construction and furniture, balancing structural support with ease of use, making them a critical component in both residential and commercial spaces.
- What materials are door hinges made of?
Common materials: steel, brass, stainless steel, and bronze—chosen for strength, corrosion resistance, or aesthetics. - How to choose the right hinge size?
Match to door weight/thickness: heavier doors need larger, sturdier hinges (e.g., 3.5" for standard interior doors). - Why do hinges squeak?
Lack of lubrication, loose screws, or misalignment. Fix with oil, tightening, or adjusting. - Can hinges be painted?
Yes, especially metal hinges—sand lightly first for better paint adhesion. - How many hinges does a door need?
Most doors use 2–3 hinges: 2 for lightweight doors, 3 for heavy/over 6ft tall ones.
