[Video] How to distinguish load-bearing walls? This can't be dismantled!

Recently, the private demolition of the load-bearing wall on the 3rd floor of a residential building in Harbin has aroused concern. So how do you tell a load-bearing wall from a non-load-bearing wall? The best way to

distinguish load-bearing walls is to look at the architectural drawings. Generally, black walls are load-bearing walls, and gray or light-colored walls are non-load-bearing walls. When

there is no picture, you can knock it by hand. The load-bearing wall is thicker and harder to knock. For non-load-bearing walls, materials such as aerated concrete or light steel keels are now commonly used, and the sound of knocking is relatively crisp and echoing.
