Description
Rail steel, produced from iron ore, has very low levels of the elements needed for weather resistance copper, nickel and chromium. Scrap metal naturally contains significant amounts of these elements (ASTM G101), giving NuPost up to seven times the weathering resistance of rail steel fence posts.Only NuPost fence post systems offer the unique combination of the key factors of superior fence post performance strength, ductility and weather resistance at no added cost.
Because Nucor uses 100% recycled scrap as raw material, we can control the chemistry of the steel we melt and the billets we cast. Nucor Utah developed a special chemistry specifically for NuPost fence posts that features lower carbon content, but includes a small amount of vanadium (commonly used in very high-quality alloy steels). This gives NuPost the strength of rail steel (ASTM A499) combined with a greater ductility.
