Door Hinge Manufacturer

• You can identify the type of hinge by its shape, size, and material. Common types include butt hinges (standard door hinges), continuous (piano) hinges, and specialty hinges like European or concealed hinges.

• A continuous hinge (also called a piano hinge) runs the entire length of the door, providing more stability and even weight distribution. A regular hinge typically has two separate plates that attach to the door and frame at specific points.

• No, not all hinge pins are removable. Some hinges are designed with non-removable pins, especially security hinges, to prevent easy detachment.

• A "normal" hinge is usually referred to as a butt hinge, which consists of two interconnecting plates (the leaves) that are mounted on the door and the frame.

• This is called a double-acting hingeor pivot hinge. These are used in doors that need to swing both directions, like saloon doors.

• A standard door hinge is typically a butt hinge, which is used for most residential and commercial doors. It has two flat, interlocking pieces of metal.

• A butterfly hingeis an ornamental hinge with a distinctive, broad shape resembling a butterfly. It’s often used for decorative purposes rather than heavy-duty applications.

• The type of hinge depends on your door size, weight, and usage. For most standard doors, butt hingesare appropriate. For heavier doors, a continuous hinge may be better. For doors that need to swing both ways, use double-acting or pivot hinges.

• The door leafof the hinge attaches to the door frame, while the door plate attaches to the door itself.

• A continuous hinge (piano hinge) spans the entire length of the door, offering better strength and support, while a regular hinge (butt hinge) typically has two separate parts, each attached to the door and the frame.

• Most standard interior doors use 2 hinges, while heavier or exterior doors may require 3 hingesfor additional support.

• A broad hinge has larger, wider leaves, offering more stability and support. Narrow hinges are typically more aesthetic and may not be as strong, but they are suitable for lightweight doors.

• Butterfly hingesare decorative and have a unique shape, while normal hinges (butt hinges) are simpler and used for more functional purposes. Butterfly hinges are often used for cabinets or ornamental doors.

• Spring-loaded hinges can be adjusted by turning a screw to change the tension. If the door isn’t closing properly, you may need to tighten or loosen the screw to increase or decrease the spring tension.

• Continuous hinges(piano hinges) are generally the strongest, providing uniform support along the entire door length. For very heavy doors, heavy-duty butt hinges or pivot hinges might also be used.

• Overlay hinges can typically be adjusted with screws to fine-tune the door’s alignment, ensuring it is level and flush with the cabinet or frame. You may adjust the hinge depth, side-to-side positioning, or the gap between the door and frame.

• Hinges should be attached to the door first, then the door is hung on the frame. This ensures alignment and makes it easier to install.

• Yes, hinge placement matters for both function and aesthetics. Typically, hinges are placed 7” from the top of the door and 11” from the bottom, with a third hinge placed in the middle for heavier doors.

• Measure 7” from the top of the door for the top hinge, 11” from the bottom for the bottom hinge, and the middle hinge should be centered between the two.

• Leave about 1/16” to 1/8”gap between the door and frame to allow room for the hinge and proper door movement.

• Yes, there are standards for door hinges based on door size, weight, and application. For example, ANSI (American National Standards Institute) sets specifications for hinge dimensions, materials, and ratings.

General hinge rules:

• Hinges should be placed in even intervals (usually 7” from the top, 11” from the bottom, with a middle hinge for heavier doors).
• Hinges should be of sufficient strength for the door’s weight.
• Placement should allow proper door movement without obstruction.

If a door doesn’t close properly, check if the hinges are loose or misaligned. Tighten screws, adjust the door frame, or replace damaged hinges. In some cases, the hinge leaf may need to be repositioned slightly.

• Yes, for most installations, hinges should be flushwith the surface of the door and frame to allow the door to swing smoothly.

• Not all door hinges are universal. While many are designed for standard doors, specialized hinges (like European hinges or double-acting hinges) are not interchangeable with standard butt hinges.

• Door hinges should be replaced when they show signs of wear, such as difficulty opening/closing, rust, or visible damage. On average, high-quality hinges last 10-15 years.

Yes, some hinges (like security hinges) are designed to be non-removable to prevent easy tampering or door removal.

• Measure the length, width, and thicknessof the existing hinge leaves, and match the new hinge to the same dimensions. Also, ensure the hole spacing matches.

• A door hinge should last 10-15 years, depending on the quality of materials, usage, and environmental conditions (e.g., exposure to moisture, humidity).
