What is 45 degree cutting steel rail?
That is the end surface of the traditional rail is perpendicular to the longitudinal axis of the rail. While the end surface of the chamfered rail is perpendicular to the bottom surface of the rail. But forms an angle of 45 dgree with the longitudinal axis of the rail. In this way. the connecting parts of adjacent rails are staggered. And the wheels will be pressed on the two sections of rails at the same time in the connecting part interval, so it can avoid the impact vibration caused by falling into the gap.
