Welded Mesh Gabions Architectural Wall Cladding - Retaining Wall for Buildings - Retaining the soil as well as decoration Welded Mesh Panel Gabions are popularly used in architectural and landscape construction by securing the gabions units, which are filled on site with stones or quarry to form the appropriate retaining wall structure, cladding and other landscape design. Filled with natural stone, the welded mesh gabions render a harminous mixing into the settings and landscape and offer a decorative effect to the building. Main types of architectural gabions welded: Galvanized steel, pvc coated or Galfan coated welded gabions. The cages are filled with stone to form a flat container form, then placed one by one and connected firmly to each other with high tensile lacing wire. They are used to build an ancient-feeling cladding for the walls in castles or villa. Welded mesh gabions inner lined with geo-mat can be used for military bastion. Reasons that gabions welded are chosen for architectural wall cladding: a, The welded mesh panel structure gabions are hot dipped galvanized or green plasticized, hence achieve the surface of bright silver or Dark green color or other colors for options. They offers different styles of decorations to the building. You can choose according to your design needs. b, The gabion boxes with hot dipped galvanized steel or plastic coated steel mesh enjoy good corrosion resistance and work for a long time. Hence can form a permanent wall cladding that is maintenance free. It will not collapse even under big scope of deforming. c, The cost of the welded mesh gabions are economic. d, The stone gabions offers a long-time-story-telling feeling and suit all castles. e, The gabions baskets are designed with collapsible structures for filling natural stones. The stones can be easily found anywhere, to save cost and to give a nature decorative effect. f, The gabions wall cladding plays the role of retaining the soil as well as decoration. g, The hexagonal twisted mesh gabions are not suitable for wall cladding as the mesh are flexible and not as solid and strong as welded mesh basket containers.
