Supported standards
JIS G4322 Stainless steel bars for concrete reinforcement
Type code
SUS304-SD, SUS410-SD

JIS products (JIS G 4322)

Features

  • Austenite stainless steel reinforcement bars made from SUS304-SD have excellent durability not only in concrete but also in outdoor environment to salt damage, and additionally are non-magnetic.
  • Ferrite stainless steel reinforcement bars made from SUS410-SD have excellent durability in the material itself that can replace steel reinforcement bars with zinc coating or epoxy resin coatings.
