The length of the rows has very little influence on the stress to which anchor points are subjected.

The solidity of the way poles are held in the ground (whether profiled steel, angle iron or T section) depends more on the depth of penetration into the ground than on the size of the pole section.

The most suitable gap is 5 m. If the gaps between poles are wider, the trellising will age faster. When the gap is wider, the poles and wires will be subjected to more stress.

In sandy soil, the poles will hold better than in clayey soil.

An inclined pole indicates that it has not been sufficiently driven into the ground.

More than 60% of the steel used in the world comes from recycling

CONTINOUS galvanization or HOT-DIP galvanization

On poles that have been treated by hot continuous sheet galvanization, the rust that appears on the edges will not migrate under the zinc.

In order to increase the solidity of wooden or concrete poles, it is necessary to increase the section size. With a pole made of profiled steel, all that is needed is thicker metal.
