They are gates, I really like the stainless steel ones.

Respected sir, I want to share one technology with you, it can be used for removal of cow dung as well as for removal of ice falling. You can make it electrical automatic. For removal of ice, we can face one problem, Ice can freeze in the system at the bottom and not allowing roller to move . Normally we will think of heating, but heating it with hot water is more convenient. From two sides or ...one side or... at the bottom of system in the middle, you put drip system, pass hot water through water pipe, ice at the bottom will melt and roller movement will become freely. Use this system for removal of ice during icefall, we can use any system for making water hot. We will not need too much hot water. Suppose building square, we can make circular cleaning system all around buildings to clean the ice. Think about it. Jay Bharat.
