32、ed and the lack of criteria of general validity. It is normally recommended for the choice to be based on SECTION 31 36 00 Page 6Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-all the available data and on the experience of existing gabion structure

Coating styles are as follows:1.3.2.1 Style 1Wire mesh made from wire which is zinc coated before being double twisted into mesh.

34、 Fasteners, lacing wire, and stiffeners are produced from zinc-coated wire. Style 1 for the wire coating is normally recommended for:a. Permanent gabion or mattress structures, for works installed in non-aggressive or non-polluted environments, and this condition remains unaltered over time;b. Tempo

Temporary gabion or mattress structures, for works in aggressive environments, depending on the minimum

37、design life of the structure.1.3.2.3 Style 3Wire mesh, lacing wire, and stiffeners as Style 1 and overcoated with PVC. Fasteners shall be of stainless steel wire. Style 3 for the wire coating is normally recommended for both permanent and temporary gabion structures, for works installed in aggressiv

38、e or polluted environments, or when the aggressiveness of the site is moderately unpredictable or variable from low to high.1.3.2.4 Style 4Wire mesh made from wire which is aluminum-coated before being double twisted into mesh. Fasteners, lacing wire, and stiffeners are also produced from aluminum-c
