HalbRunden

HalbRunden is a term used in woodworking and construction to describe profiles with a semi-circular cross-section. The shape is created by forming a half-cylinder along the length of a strip, block, or extruded material. HalbRunden are commonly used as decorative edging, trim, or edge protection in furniture, cabinetry, paneling, and architectural details.

Production and variants

HalbRunden can be produced by turning, routing, or milling from solid wood, laminated wood, plastics, or metals. They are sold as ready-made HalbRundleisten (half-round strips), HalbRundprofile (half-round profiles), or as semi-cylindrical edging components. Available radii range from small (a few millimeters) to larger sizes, and lengths are typically 2 to 4 meters for boards and mouldings. Finishes include natural wood, stained, painted, or coated plastics and composites.

Applications

The primary use of HalbRunden is to create rounded edges and decorative contours on furniture, doors, window frames, paneling, and stairs. They provide a smooth transition between surfaces, soften sharp corners, and can be used as functional trim to hide joints or gaps. In carpentry, HalbRunden may be combined with other molding profiles to achieve various stylistic effects, from traditional to contemporary.

Materials and care

Common materials include softwood and hardwood species, plywood or laminated veneers, PVC or acrylic plastics, and lightweight metals. Finishing often involves sanding, sealing, staining, and varnishing for wood, or cleaning and mild maintenance for plastics and metals.
