Wooden Snow Fence Specifications
Snow fencing consists of wood slats woven together with five 2-wire strands of galvanized wire. Proper snow fence construction causes snow to drift downwind, allowing water to collect in a reservoir area or other suitable retention area. It can prevent snow from accumulating in unwanted drifts. An eddy forms behind the fence whenever wind passes over it, creating a rolling wind current that flows downward and to the back side of the fence. This formation creates fast and slow areas in the wind, causing a drift to form in front of the fence on the windward side.
Materials Used
Slats are made of No. 1 Aspen, Spruce, Poplar, or Southern Yellow Pine measuring three-eighths (3/8") inches thick, one and one-half (1 1/2") inches wide, and forty-eight (48") inches high. Permissible variation in width shall not exceed one-sixteenth (1/16”) inch, and in length shall not exceed one-quarter (1/4”) inch. Thickness shall be a minimum of three-eights (3/8”) inches thick but shall not exceed nine-sixteenths (9/16”) inches thick. Both ends shall be cut square. Paint the slats with a good-quality red iron oxide stain. The steel base metal of the wire shall be of excellent commercial quality. The galvanized wire shall not be less than thirteen (13) steel wire gauge. The weight of the coating shall not be less than three-tenths (0.3) ounce per square foot of uncoated wire surface, determined by AASCO Designation T65 (Class I). Weight of Coating on Zinc-Coated (Galvanized) Iron on Steel Articles. The zinc coating shall adhere to the wire without flaking and without being removable by rubbing with bare fingers when the wire is bent completely around a pin of the same diameter as the wire.
Wooden Snow Fence Fabrication
The slats are spaced two and one-quarter (2 1/4") inches apart plus or minus 1/4", and there should not be less than two (2) three hundred and sixty (360) degree twists of the wire in the weave between the slats. The fabric must be tightly woven so that the wire is forced into the wood slats sufficiently to hold them tightly. The strands of wire shall be spaced ten (10) inches apart and four (4) inches from the ends of the slat. Stretch the fence after weaving and before rolling.
