Thousands of years ago, Egyptians weaved baskets of reeds, put stones in them and buried them in the Nile to resist the erosion of the river. Then Europeans used wicker baskets to make military defenses and flood defenses. The baskets now receive the name "Large Cage" from the Italian "Gabbione". In the mid-nineteenth century, the first commercial gabion braid appeared. The mid-twentieth century, gabion box has undergone a reform, gabion welding technology available. Over time, Gabion has been continuously improved while maintaining its optimal advantage. Each reform reflects the progress of production and design. Improved product material to strengthen, advanced technology, practicality. Welding gabion mesh is made of high-quality steel welded cage. In the box filled with rock or natural pebbles, can be used for highway, slope protection, roadway protection, bridge protection, retaining walls and so on. Has the advantages of permeability, integrity.
 
The gabion box is made of woven braid of high corrosion-resistant, high-strength, ductile low-carbon steel wire or PVC-coated steel wire. The box-type structure made from the net is a stone cage. According to ASTM and EN standards, the diameter of the low carbon steel wire used varies according to the engineering design requirements. Generally between 2.0-4.0mm, gabion wire tensile strength of not less than 38kg / m2, the weight of the metal coating is generally higher than 245g / m2, gabion mesh edge line diameter is generally thicker than the diameter of the wire. The length of the double stranded part shall not be less than 50mm, so as to ensure the metal plating and PVC coating of the stranded wire are not damaged.
