We make smooth and ribbed wire grade B500A according to PN-H-93247-1 -Joinable steel B500A for concrete reinforcement, Part 1: Ribbed wire
(steel class A-III-N) of raised properties:

  • yield point Re min = 500 MPa
  • tensile strength Rm min = 550 MPa

    Out of cold-ribbed wires and bars we make welded steel meshes according to PN-H-93247-2 -Joinable steel B500A for concrete reinforcement, Part 2: Welded reinforcement meshes and top reinforcement bearings.
