| TERMINOLOGY |
1. Definitions - Refer to Terminology A 902 for general terminology relating to metallic-coated steel
products. |
| |
| 2. Descriptions of Terms Specific to this Standard: |
2.1. Gabion, n-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. (Figure 1). Typical gabion sizes are shown in
Table 2.
2.2. Gabion mattress, n-a gabion with relatively small height in relation to the lateral
dimensions, generally used for lining channels. (Figure 2). Typical gabion mattress sizes
are shown in Table 3.
2.3. Llacing wire, n-for gabions and gabion mattresses, a metallic coated steel wire or metallic
coated steel wire with PVC coating used to assemble and interconnect empty gabion
units, and to close and secure stone filled units, used as an alternate to spiral binders.
2.4. Spiral binder, n-for gabions and gabion mattresses, a length of metallic coated steel wire
or metallic coated steel wire with PVC coating preformed into a spiral, used to assemble
and interconnect empty gabion units, and to close and secure stone filled units, used as
an alternate to lacing wire.
2.5. Stiffener, n-for gabions, a length of metallic coated steel wire or metallic coated steel wire with PVC coating used for support by forming a diagonal brace across the corners, inside of the gabion container. Stiffeners are produced using lacing wire for on site applications or shipped preformed using heavier wire gauge as shown in Table I.
2.6. Welded wire fabric, n-material composed of a series of longitudinal and transverse steel wires arranged substantially at right angles to each other, and welded together at the points of intersection by electrical resistance welding to form fabricated sheets. |

| CLASSIFICATION |
| 1. Welded wire gabions are classified according to the coating as follows: |
1.1. 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 zinccoated
wire.
1.2. 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.
1.3. Style 3 consists of welded wire fabric made from wire which is coated with zinc-5%
aluminum-mischmetal alloy (Zn-5AI-MM) before being welded into fabric. Spiral binders,
lacing wire, and stiffeners are also produced from zinc-5% aluminum-mischmetal alloy
(Zn-5AI-MM).
1.4. Style 4 consists of welded wire fabric made from wire which is aluminum coated before
being welded into fabric. Spiral binders, lacing wire, and stiffeners are also produced from
aluminum coated (Aluminized) wire.
1.5. Style 5 consists of welded wire fabric, spiral binders, lacing wire, and stiffeners as Styles 1,
2, 3, or 4, and overcoated with PVC. |
