1064.01 Description
1.This Section covers chain-lin k fence, woven wire fence, barbed wire fence, and the posts, fabric, wire, staples, ties, and fittings used in the construction of these fences.
1064.02 Material Characteristics
1.Chain-link Fence:
a.Approved types: (1) Zinc-coated steel chain-link fence fabric shall conform to the requirements of ASTM A 392. The fabric shall be zinc-coated after weaving with a Class 2 coating.
2.Aluminum-coated steel chain-link fence fabric shall conform to the requirements of ASTM A 491. The fabric shall be aluminum- coated before weaving.
3.Zinc 5% aluminum-misc hmetal alloy-coated steel chain link fence shall conform to the require ments of ASTM F 1345. The fabric shall be coated before weavin g with a Class 2 coating.
4.Vinyl-coated steel chain-link fence fabric shall conform to the requirements of Federal Specif ication RR-F-191/1. The vinyl coating shall be thermally bonded over the fa bric and be the color shown in the contract.
5.The fabric shall be the he ight specified in the contract. Wire shall be 9 gauge [0.1 48 inch (3.76 mm)] in diameter. Mesh openings shall be 2 inches (50 mm).
b.Steel Fence Posts, Braces, and Rails: (1) Tubular steel pipe used for line posts, end posts, corner posts, pull posts, top rail, and brace ra il shall be of the nominal pipe size (NPS) shown in the contract.
2.Tubular steel pipe shall conform to the requirements of ASTM F 1083 Schedule 40 pipe. Pipe shall be coated in accordance with ASTM F 1043, Types A or C.
3.Tubular steel pipe other than ASTM F 1083 Schedule 40 pipe meeting the outside dimens ional requirements of ASTM F 1083 Schedule 40 pipe may be used provided the product of the yield strength of the pipe multiplied by its section modu lus is not less than the product of the section modulus of an equivalent diameter F 1083 Schedule 40 pipe multiplied by 25,800 psi (180 MPa). Pipe meeting these requirements shall be hot-dipped galvanized in accordance with the applicable requirements of ASTM F 1083 or be coated as follows:
i.The exterior surface shall be hot-dipped galvanized with a minimum of 0.9 oz/ft² (275 g/m
2.and have a uniform, chromate conversion coating applied. The hot dipped galvanized exterior shall also be top coated with a clear organic coati ng such as urethane or polyurethane (the chromate conversion coating being applied either as a separate treatment or simultaneously with the organic topcoat).
