This back gate conveniences the way of students, but the intensity of using is still low. Therefore the condition of rusting is slight.

However, the position of connection over the gate (bending areas) could have been corroded much more seriously. This could lead to a total destruction to the gate if the no actions take place.

Painting and adding oil to the small areas or changing the connecting elements to the wall (if possible) are likely to solve this problem. It is costly to re-galvanize the gate.
