94 million beef cattle, 9 million dairy cows on 1 million
cattle ranches, 31,000 dairy farms in the USA. Av. property 434 acres, 3.3 miles (5.3km) perimeter fencing. Including internal fencing (likely x 5) 16.5 miles (26.5km) per property x 1.31 million properties = 21.6 million miles (34.7 million km) of cattle fencing in the USA.
A post every 16.5 feet (5m) / 320 posts per mile (200 per km) = 69.1 billion existing posts. Likely 10% of existing posts are replaced yearly (6.9 billion). If TUFF post takes 10% of that 10%, potential sales are 690 million . Add Australia market (7.2% of USA) and 739 million TUFF posts would be sold each year.
