Extranet FR Viticulture Arboriculture Advice Contact ADVICE HOME ADVICE ADVICE DID YOU KNOW? CHOICE OF STEEL Profile steel posts are made essentially from two families of steel, those starting with the letters DX (DX51, DX52 ...) and those starting with the letter S (S235, S250 ...). ELASTIC RESISTANCE is the main characteristic to take into account. STEEL DX 51: DX = mild steels for cold roll forming. Elastic resistance from 15KgF / mm². STEEL S 250: S = standard steels for construction (buildings, bridges, boats, etc.) Elastic resistance from 25KgF / mm². (+ 40%) For the same profile and the same weight, an S250 steel stake will have a theoretical elastic resistance at least 45% greater than a DX51 steel stake.
