Why the post of the isolation fence is curved

The bending of the column of the isolation fence is to bend about 30 ° to the side at the upper part of the column. This type of column is very common. Let us first introduce the application of this type of column:
In terms of isolation grids made of welded mesh, some of the framed meshes are generally matched with upright columns. Because the frames are upright, they are not made into bends in many ways. A kind of frame mesh is added with a frame horizontal bar at the bend, and the upper mesh and the left and right borders of the bending are uniformly bent to one side; the isolation grid without the frame is uniformly bent.
So why does the isolation fence need to be bent?
1. Bending outward, it can prevent people from climbing well;
2. Barbed wire can be installed on the bend to better protect the safety of the area around it;
3. Beautiful appearance, increased the shape of the isolation barrier.
