This specification covers the material, design, and dimensional requirements for horizontal slide chain link fence gates, gate posts, and other accessories and components for industrial and commercial applications. The horizontal slide gates covered here shall be of the following types: Type I—overhead slide gates that are supported only from above; and Type II—cantilever slide gates spanning an opening lacking a top or bottom support within that opening. Furthermore, Type II gates shall be supplied in any of the two classes as follows: Class 1— steel frame gates and aluminum frame gates using external rollers; and Class 2— frame gates and aluminum frame gates using internal rollers. Gates of either type and class shall conform to material and manufacture requirements specified for zinc-coated steel frames, aluminum alloy gate frames, polymer-coated steel or aluminum frames, chain link gate fabric, barbed wire top, and barbed tape. Type I gates shall additionally meet the specified requirements for materials and manufacture, shape and size, dimension and weight, gate posts, gate support members, roller assembly, gate extensions, and gate extension bracing. Conversely, Type II gates shall additionally meet the specified requirements for shape and size, gate posts, guide posts (for Class 1 only), roller assembly (external and internal rollers, top roller guards, and bottom protective plates), performance criteria, field adjustment, and latching.
