HEA panel (high Energy Absorption) is a wire mesh made from weaving a single high strength Galvan coated steel wire rope into a panel that can be anchored onto rocky slope to mass loosened rocks. A special steel knot binds intercepting steel wire rope with strong unraveling force. Panels are anchored by soil nails and can be shackled together for large coverage. The entire unstable slope can be dressed up as active rockfall protection.
