Hexagonal Wire Mesh Rolls, also known as Gabion Rolls, are made from low-carbon steel wire, which is cold galvanized, hot galvanized, or plastic-coated, and then woven into heavy-duty hexagonal mesh. The Gabion Rolls are categorized into hot-dipped galvanized, cold-dipped galvanized, plastic-coated, and Galfan (aluminum-zinc alloy) rolls. The wire diameter of the Gabion Rolls typically ranges from 150mm to 400mm, with the hot-dipped galvanized coating ranging from 240g/m² to 500g/m², and the cold-dipped galvanized coating generally from 10g/m² to 30g/m².
