Sack gabionis cylindrical basket made of 8x10 double twisted steel woven wire mesh, with mechanical characteristics higher than the ones suggested from EN 10223-3. It's filled with stones at the project site to form flexible and permeable structures used for emergency and river training works where local conditions require fast installation or where the water does not allow for easy access to the site and where underwater installation is necessary.
Sack gabionsare supplied with steel reinforcing wires inserted during the manufacturing process to facilitate closing during installation. The wire used for the manufacture of gabion shall have a tensile strength between 3 80-550N/mm2 exceeding, in order to increase the tensile resistance of the finished products, what is suggested from EN10223-3. Wire tolerances are in accordance with EN 10218. Elongation shall not be less than 10%, according to EN 10223-3. Test must be carried out on a sample at least 25 cm long. Meantime the adhesion of the zinc coating to the wire shall be such that, when the wire is wrapped six turns around a mandrel having four times the diameter of the wire, it does not flake or crack when rubbing it with the bare fingers.

Surface treatment: electro galvanized or hot dipped galvanized
