ASTM A975 Standard Hot Dipped Galvanized reno mattress gabion baskets For Erosion Control Projects
Gabions are baskets manufactured from 8x10 double twisted hexagonal woven steel wire mesh, as per ASTM A975-97 Gabions 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 is heavily Galfan (zinc-5% aluminum-mischmetal [Zn-5 Al-MM] alloy) coated soft temper steel. A PVC coating is then applied to provide additional protection for use in polluted, contaminated or aggressive environments: in salt, fresh water, acid soil or wherever the risk of corrosion is present. The PVC coating has a nominal thickness of 0.02 in. (0.50 mm). The Gabion is divided into cells by diaphragms positioned at approximately 3 ft (0.9m) centers. To reinforce the structure, all mesh panel edges are selvedged with a wire having a greater diameter. Gabions shall be manufactured and shipped with all components mechanically connected at the production facility.
All tests on wire must be performed prior to manufacturing the mesh. All wire should comply with ASTM A975-97, style 3 coating, Galfan and PVC coated steel wire. Wire used for the manufacture of Gabions and the lacing wire, shall have a maximum tensile strength of 75 000 psi (515 MPa) as per ASTM A856-03, soft temper steel.
Superior to rigid type structures. The hexagonal mesh construction permits natural adjustment to varying conditions of earth settlement without causing fracture or collapse of the structure.
Gaps between the stones silt up naturally as time passes. Silting supports the growth of grass and plants which serve as a bonding agent for the stone.
A Gabion structure allows water to pass through, water pressure cannot build up behind it and the structure is continuously drained.
The flexibility of the Gabion structure provides the inherent strength to withstand and dissipate pressures exerted by water and earth masses.
Filling materials are usually found on or near the site. No structural maintenance is needed and foundation work is usually unnecessary.
6. NATURAL APPEARANCE
Natural stone makes the structure aesthetically pleasing especially when subsequent vegetation growth takes place.
Unskilled labour can be used for quick assembly.
Gabion structures are easily maintained using additional mesh or grouting.
Once the structure is built there is no waiting period – it functions immediately.
Extensions are simple. Additional units are simply attached to the existing ones.
