Welded Gabion

Welded gabion, a wire fabric container, uniformly partitioned, of variable size, interconnected with other similar containers, and filled with stone at the site of use, to form flexible, permeable, monolithic structures such as retaining walls, sea walls, channel linings, revetments, and weirs for erosion control.


Welded gabion are classified according to coating, as follows:


Style 1, consists of welded wire fabric made from wire which is zinc coated before being welded into fabric. Spiral

binders, lacing wire, and stiffeners are produced from zinc coated wire.


Style 2, consists of welded wire fabric which is made from uncoated wire and the fabric is subsequently zinc coated after fabrication. Spiral binders, lacing wire, and stiffeners are produced from zinc coated wire.


Style 3, consists of welded wire fabric made from wire which is coated with zinc-5 % aluminum-mischmetal alloy (Zn-5Al-MM) before being welded into fabric. Spiral binders, lacing wire, and stiffeners are also produced from zinc-5 % aluminum-mischmetal alloy (Zn-5Al-MM) coated wire.
