The HEA Panel (High Energy Absorption) combines high strength features of the wire rope with the steel knot.

The knot is made by two bindings, each one obtained by looping a pair of steel 3,00 mm wires coated with a 95% Zinc-Aluminium, 5% Mischmetal alloy. The two bindings tightly envelope the ropes crossing each other.

The panel is made of square meshes manufactured with one rope, closed by an aluminium pressed spinning cot, with resistance not less than 90% of the rope breaking load.
