These structures are made of steel and are used on the ground in various continuous rows over the width of the avalanche starting zone.
The distance between the rows depends on the angle of the slope and the thickness of the snow.
Its height should be at least equal to the height of the thickness of snow expected for the period being considered.
Initially, these structures were of a rigid type, but nowadays mostly the flexible type is used as they are lighter and faster to assemble and have less visual impact.
