Welded Gabion is high quality steel mesh. They can be filled on site with hard durable stone materials to form mass gravity retaining structures. Owing to their inflexibility, welded gabions can not adapt to differential settlement or be used in water courses. In comparison with woven wire gabions, welded gabions offer a higher strength. In order to meet different project requirements, various wire diameters and unit sizes are available for welded gabion boxes.
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.
