Wooden Snow Fence Specifications
Snow fencing consists of wood slats woven together with five 2-wire strands of galvanized wire. The proper construction of a snow fence causes snow to drift down-wind of it, allowing for water collection in a reservoir area or suitable water retention. It can prevent snow from accumulating in drifts where it is not wanted. An eddy will form behind the fence whenever the wind passes over it, causing a rolling wind current that flows downward and to the back side of the fence. This formation will cause fast and slow places to develop in the wind, which makes a drift form in front of the fence on the windward side.
Slats are made of No. 1 Aspen, Spruce, Poplar, or Southern Yellow Pine measuring three-eight inches (3/8”) thick, one and one-half (1 ½”) inches wide, and forty-eight (48”) inches high. The permissible variation in width shall not exceed one-sixteenth (1/16”) inch and one-quarter (1/4”) inch in length. 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. The slats shall be painted with a good-quality of 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 that of the wire.
Wooden Snow Fence Fabrication
The slats are spaced two and one-quarter (2 ¼”) inches apart plus or minus ¼”, 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. The fence shall be stretched after weaving and before being placed in rolls.
