Gabion

The gabion mattress is a flexible and permeable structure made of double twisted hexagonal wire mesh. It is of great significance in river bank protection and as channel linings for erosion control. Usually the heavily zinc-coated soft temper steel is used to make the gabion mattress.

Generally, the thickness of the gabion mattresses (also called Reno mattress) can range form 0.15 to 0.5m. The tolerances of mattress' dimensions are 3% up and down in length, 3% up and down in width and 2.5cm up and down in height. Various specifications of different lengths, widths and heights can be supplied. In order to make the gabion mattresses be with a high strength, all the edges of the mattress are selvedged with wire of greater diameter. Typically standard sizes of gabion mattresses are 3mx2mx0.3m and they are usually covered with zinc or PVC coating. Gabion mattress has a hexagonal mesh with the opening of 80x100mm with 2.5mm mesh wire and 3.0mm selvedge wire diameter. All gabions and mattresses are supplied with the baskets and are used to lace together the mesh panels during the process of installation.

Application:
Gabion mattresses plays an important part in preventing natural scour of water and retaining earth. It is mainly applied for river bank protection as well as foreshore and side slope protection. Meanwhile, it provides protection on water courses and coastal revetments against scour and erosion.
