We supply ASTM A153 hot galvanized S355 JR anchor-bolts.


Anchor-bolts represent the best tools to grant a safe fastening between metal frameworks and concrete bases since they grant static hold in case of sinking or tearings in the concrete structure. These items are subject to quality control aimed at granting the performance requested during the product design (cold resilience materials can be supplied too).



Our anchor-bolts are available in several dimensions and shape (umbrella, straight, L-shaped, open/close sling, with welded plates, welded pipes, etc.).

S 355 JR chemical composition:


C = carbon max 0,24%

Mn = manganese max 1,60%

Si =  silicon max 0,55%

S = sulphur max 0,045

P = phosphorus max 0,045%



The production process for the fire galvanized S355JR anchor-bolts ends with hot galvanizing, a well-known technique which by means of a 420°C molten zinc bath allows to completely coat the product to preserve it from corrosion.
