Round corners on hardware, which may be on hinges, or other hardware items, such as ballcatches. This is one of the three standard corners on a door hinge.

For ease of use in machining, round corners are normally used, and our company prefers 1/4" radius where possible, and the square corners otherwise.

Three (3) Panel Doors:
3 panel doors have three panels in the door. These doors have flat panels. The three panel flat panel designs are very popular arts and crafts type styles. We do not manufacture doors with three raised panels due to expansion and contraction problems in the wood that may cause cracking.
Veneer Flat Panel Doors:
Veneer flat panel doors are doors that have flat panels with veneered wood laminated over a stable surface, usually something stable such as plywood. In some cases, MDF (Multi-Density Fiberboard) is also used. The plywood is usually the more stable of the two. In very wide panels, this veneered panel is more stable than a solid wood panel for purposes of expansion and contraction.
Wood Interior Doors:
Wood interior doors are doors made out of wood for the interior of a building. These doors may be available in hardwood or softwood varieties. Hardwoods include such woods as oak, maple, cherry, walnut, and related woods. Softwoods include woods such as pine, fir, and spruce. The real difference between hardwoods and softwoods is not always the hardness of the wood, but the type of tree that the wood is from. Coniferous treees (softwoods) have needles, and are also called evergreens. Deciduous trees (hardwoods) have leaves that are seasonal and the trees grow new leaves every year. Some hardwoods are softer than some softwood varieties, or vice versa.
