MODERSOHN supplies stainless reinforcing ribbed steel made of stainless steel with building authority approval from DIBT, Berlin. In addition to A4/A5 steels (1.4404/1.4571), we also supply ribbed reinforcing steel made of stainless Lean Duplex steel D4 (1.4362). The high basic strength, the good bonding effect in the concrete (due to the ferritic microstructure) and a favourable price due to lower alloying element contents make this material an economical and technically superior alternative.
The MODERSOHN company stores both the classic A4 types from diameter 6 to 14 mm and the Lean Duplex steel from diameter 6 - 12 mm.
