Wood Snow Fence Specifications.pdf

The document is a set of specifications for a Wood Slat Snow Fence issued by the Iowa Department of Transportation. The specifications detail the requirements for a snow fence constructed from wood slats tightly woven together with galvanized wire cables, with precise guidelines for materials, dimensions, and manufacturing. The wood slats must be Southern Pine, Douglas-fir, or Northern Hardwood, measuring 3/8 inch by 1-1/2 inches, cut with square ends to a length of 47-1/2 to 48-1/2 inches, and free from defects. The fence is to be constructed with four galvanized wire cables, each consisting of two 13-gauge wires, and shall be furnished in 50-foot rolls.

The specifications include detailed requirements for the fence components, including wire cable coating standards (meeting ASTM A 116, class 1 coating), painting (red iron oxide), and quality control measures. The document allows for sampling and testing, with provisions for requesting samples from up to 10 percent of wire or snow fence bundles in a shipment. Each sample will be tested for coating weight and quality. The specifications ensure the snow fence meets strict manufacturing standards, with requirements for wire coating smoothness, absence of defects, and seasonal seasoning of the wood slats.
