GABION BASKETS

Specifications

Our baskets are made from Class A galvanized mild tensile steel wire in accordance with the SANS 675 specification. The baskets and mattresses are manufactured in strict accordance with the SANS 1580 and site installations are also in accordance with the latest SANS 1200 specification.

Gabions

Our mesh is hexagonal in shape meeting with the 80×100 mm mesh aperture for gabions with a mesh wire diameter of 2.7mm and selvedge wire of 3.4mm diameter. Contact us also for welded mesh gabion material as well.

Standard Sizes

The sizes offered are shown below together with their volumes, we can make other sizes where required or necessary.

River Mattresses

Mattresses also have a hexagonal mesh spec. of 80×100mm with 2.5mm mesh wire and 3.0mm selvage wire diameter. All gabions and mattresses use a 2.20mm wire diameter lacing wire which is supplied with the baskets and used to lace together the mesh panels during the erection process.

Mattresses and gabion baskets are also available with a 0.5mm nominal thickness P.V.C. coating to enhance the resistance of the baskets to corrosion of the wire mesh. This provides a overall increase in diameter of 1mm to all wires used in the manufacturing process.
