Gabion Baskets are manufacture from 8x10 double twisted hexagonal woven steel wire mesh, as per ASTM A975-97 Gabion Basket are filled with stones at the project site to form flexible, permeable, monolithic structures such as retaining walls, channel linings, and weirs for erosion control projects.
The steel wire used in the manufacture of the Gabion Basket is heavily Galfan (zinc – 5% aluminum – mischmetal [Zn – 5 Al - MN] alloy) coated on soft temper steel. A PVC coating is then applied to provide additional protection for use in corrosion or polluted, contaminated or aggressive environments: in salt, acid soil, fresh water or wherever the risk of corrosion is present. The PVC coating has a nominal thickness of 0.02 in. (0.50mm). The Gabion Basket is divided into cells by diaphragms positioned at approximately 3 ft (0.9mm) centers. To reinforce the structure, all mesh panel edges are selvedge with a wire having a greater diameter. Gabion Baskets shall be manufactured and shipped with all components mechanically connected at the production facility.
Gabion Basket Wire:
All tests on wire must be performed prior to manufacturing the Gabion Basket. All wire should comply with ASTM A975-97, style 3 coating, Galfan and PVC coated steel wire. Wire used for manufacture of Gabion Basket and the lacing wire, shall have a maximum strength of 75 000 psi (515 Mpa) as per ASTM A856-03, soft temper steel.
Gabion Basket Features
- Economic
- Just fill the stone into the gabions and seal it
- Simples installation
- No special technology needed. Weather proof under natural destroy, corrosion resistant
- No collapse even under big scope of deforming
- Sludge in the stones is good for plant growing
- Mixed to form a integrity with the natural environment. Good permeation can prevent the damage by hydrostatic
- Less transport freight. It can be folded together for transport and installation
