MMFX Steel Corporation of America has received approval from the Pennsylvania Department of Transportation (PennDOT) for MMFX2 (AASHTO MP 18) Grade 100 reinforcing steel bar for use in bridge structures.
MMFX2 will be listed in PennDOT’s Bulletin 15 ‘Approved Construction Materials’. This approval means structural engineers can now use MMFX2 rebar and utilise the high-strength properties of this 100 ksi rebar to create more efficient bridge designs in Pennsylvania.
Pennsylvania is working to fix a large number of bridges that are in need of repair or replacement. The new PennDOT Bulletin 15 approval will allow MMFX Steel to support Pennsylvania’s need to build bridges that increase bridge life while reducing build cost.
MMFX2 rebar has been proven to exceed the 100-year service life requirements common in many of today’s bridge specifications. Because MMFX2 provides corrosion protection without a coating, it eliminates the common construction problems and costs of coated rebar such as coating damage, special handling and additional project quality inspections. Grade 100 MMFX2 high-strength rebar will make it possible for PennDOT bridges to be designed and built with 20 to 50% less steel, which could result in up to 60% lower labour costs for rebar fabrication and placing.
