Wood door bars come in various profiles, each serving a specific function and aesthetic purpose. T-profiles are shaped like the letter "T" and are typically used to join two wood panels of equal height, providing both structural support and a clean visual transition. End profiles are designed to neatly finish the exposed edge of a door or panel, offering protection against wear while enhancing appearance. Ramp profiles feature a sloped surface, making them ideal for bridging height differences between floor surfaces or creating a smooth transition at thresholds. Each type plays a key role in durability, safety, and the overall finish of wooden doors.
