The Stone gabion box is made of hexagonal or square hole mesh panel from the the materials of Galvanized wire, galfan wire or pvc wire. According to ASTM and EN standards, the diameter of the low-carbon steel wire used varies according to engineering design requirements. If it is galvanized wire or zinc-aluminum wire, wire diameter is 2.0mm to 4.0mm, if it is a hexagonal gabion box with PVC coated, Normally the outer diameter is 3.0mm to 4.0mm including the PVC coated layer. The selvage wire diameter is thicker than the main wire . The tensile strength of the gabion box is not less than 38kg / m2, the galvanized layer can reach 300g / m2, and the length of the twist wire should not be less than 50 mm to ensure the metal coating and PVC coating of the stranded part of the wire The layer is not damaged.
Stone gabion box has different materials that every type have different advantages. When choosing, it should be selected based on the specific application.
1. High-quality low-carbon steel wire or galvanized wire. The surface of the wire is protected by hot-dip galvanizing or cold-galvanizing. The thickness of the galvanized protective layer is made according to customer requirements which can be 300g/m2.
2. Zinc aluminum alloy steel wire (Galfan Wire ), which is an international emerging stone gabion box materials in recent years, including the following feature, corrosion resistance is traditional pure galvanized More than three times the diameter of the wire can reach 2.0MM-4.0MM, and the tensile strength of the wire is not less than 380Mpa.
3. Galvanized steel wire covered plastic: High-quality low-carbon steel wire, covered with a PVC or PE protective layer on the surface of the steel wire, and then woven into gabion nets of various specifications. This protective layer will greatly increase the protection in highly polluting environments, and through the choice of different colors, it can be integrated with the surrounding environment.
4. Stainless steel wire, this wire has strong anti-corrosion performance and but normally it is the high cost.
The service life of the stone gabion box is closely related to the anticorrosive performance of the material. Therefore, it is of great significance to do the anticorrosive work of the gabion box. The research found that the service life of the gabion box mainly depends on the life of the materials. The use fo stone gabion boc is related to the water normally. In order to prevent the gabion box from rusting after long-term soaking in the water stream, we will choose the surface treatment is galvanized or plastic-coated gabions to ensure the service life of stone gabion box.
