Large Round Corner Guard Strip
Exterior corners refer to protruding angles, while interior corners are those that are recessed. For example: the 90-degree angle at the edge of a room window is an exterior corner. The recessed angle where walls meet is an interior corner. The terms exterior corner or interior corner here refer to the specific location of these corners!
Exterior corner strips, also known as exterior corner trim or corner strips, are decorative strips used for finishing 90-degree protruding corners of tiles. They are designed with a 90-degree fan-shaped arc on one side, with the base plate facing outward, and are made of materials such as PVC, aluminum alloy, or stainless steel.
Interior and exterior corners do not necessarily have to be 90 degrees or close to 90 degrees. Depending on the specific layout of the space, the angles may vary, but most corners are indeed around 90 degrees. In short: recessed corners are interior corners, and protruding corners are exterior corners. Evaluating the craftsmanship of tilers and painters based on how they handle interior and exterior corners is crucial. Whether they are straight, vertical, and level is key to determining the skill level of tilers and painters.
