For Hexagonal gabion box, the hole is made from hexagonal wire netting by galvanized wire, PVC wire, Galfan wire through double twisted and triple twisted. It help the whole gabion structure solid enough. The common type is double twist hexagonal gabion basket. If considering some the high erosion and impact conditions, the triple twisted is more strong and durable. It can supply higher tensile strength to the gabion box.
No matter Double twist and triple twist all can supply high tensile strength, flexible high corrosion and rust resistance and chemical stability, Water can pass through the gap of stones to reduce the withstand the erosive forces of the water.
Everyone could choose the different materials and twist type , it will be a economical and practical for you and Maintenance free too.
