steel wire conforming to ASTM A491, or galvanized 0.148-inch (No. 9 gage) steel wire top and bottom with galvanized 0.120-inch (No. 11 gage) steel intermediate wires. Join vertical stays at each horizontal wire by electric arc welding or by a hinge-type method, consisting of not less than 1 1/4 tightly wrapped twists. Galvanize at a minimum of 0.6 ounce per square foot of actual surface area, as specified in Section

1110.04

galvanized staples set in the post flanges, or another acceptable method.

1110.02END POSTS, CORNER AND PULL POSTS, LINE POSTS, BRACES, STRETCHER BARS, TRUSS

RODS, FITTINGS, AND HARDWARE—As shown on the Standard Drawings and as follows:

• Straight posts true to section.

• Braces, fittings, and hardware of commercial-quality steel or malleable iron.

• Posts of commercial quality steel or malleable iron, or Aluminum Alloys 6063-T6, 6005-T5, or 6061-T6, according to ASTM B221; tubular and open type sections.

• Moisture-excluding caps, firmly and rigidly secured to the post top.

Galvanize or coat both the inside and outside of tubular and open -type sections, according to AASHTO M 111. Either of two alternate coating systems may be used, as follows:

• Outside. Hot-dipped zinc coating, according to ASTM B6, at a minimum of 1.0 ± 0.1 ounce per square foot of actual surface area; chromate conversion coating at 30 micrograms per square inch ± 15 micrograms per square inch of actual surface area; thermoplastic electrostatically applied acrylic coating, 0.5 mil ± 0.2 mil in thickness.

and

• Inside. Zinc base coating, 0.5 mil ± 0.2 mil thickness (0.3 ounce per square foot ± 0.05 ounce per square foot) with a minimum of 80% zinc powder by weight.

or

• Outside and Inside. Hot-dipped, pure, aluminum coating, commonly identified as Type 2, with a minimum weight of coating of 0.75 ounce per square foot of actual surface area, triple spot test, and 0.70 ounce per square foot of actual surface area, single spot test, as measured according to AASHTO T 213; a chromate conversion coating; and a thin acrylic resin film.

1110.03GATES—As shown on the Standard Drawings and as follows:

• Swing-type gates, with latches, stops, keepers, hinges, and locks.

• Steel wire fabric of same type material as the fence.

• Hinges of adequate strength to support the gate, and that do not twist or turn under the gate's action.

• Plungebar-type latches that can be locked, full gate height, and located in a manner that engages the gate stop.

Forked latches may be allowed, for single gates less than 10 feet wide.

• Stops are to consist of a flush plate, anchored in concrete, to engage the plungebar of the latch.

• Other types of stops may be allowed, for single gates less than 10 feet wide.

• Substantial devices are necessary for securing and supporting the free end of the gate in an open position.

GALVANIZING—Galvanize fabric, posts, post caps, braces, fittings, and hardware, by electrolytic,

hop-dip, mechanical, or other acceptable methods as specified in Section 1105.02(s) and as follows:

For electrolytic method: ASTM B633

For hot-dip method:

• Posts, braces, and fittings. ASTM A123 or ASTM A53

• Fabric. ASTM A392

• Hardware. ASTM A153

For mechanical method (hardware only): ASTM B695

Test galvanizing by weight, according to ASTM A90.

1110.05INSPECTION—Material will be inspected, if considered necessary, at the place of manufacture,

before shipment. Provide facilities for the Department inspector to determine that the material is being furnished as indicated.
