ChrōmX 9000 Series
HIGH STRENGTH REBAR AND CORROSION RESISTANT REBAR
Unmatched Value from Beginning to End
ChrōmX® 9000 Series (ChrōmX 9100 and 9120) concrete reinforcing steels offer both high strength and corrosion resistance solving difficult design and construction challenges. Utilizing high strength of ChrōmX 9000 steel can relieve rebar congestion, lower material requirements, and save construction time and labor. The product’s corrosion protection extends the service life and reduces the life cycle cost for concrete structures even in highly corrosive environments. Its uncoated corrosion protection means no additional cost from special handling, coating inspection and repair.
HIGH STRENGTH REBAR WITH DUCTILITY
The unique microstructure of ChromX 9000 Series reinforcing steel achieves the 100 and 120 ksi yield strengths of the ASTM A1035 specification, while maintaining excellent ductility and tensile-to-yield ratios above 1.25. The design guidance for using high strength steels up to 100 ksi yield within the AASHTO LRFD Bridge Design Specifications, as well as ACI ITG-6R, ICC-ES AC429 and ICC-ES ESR-2107 allows engineers to design bridges and other concrete structures with Grade 100 steel. Utilizing the high strength properties of ChromX 9000 steel can lower initial material costs, solve rebar congestion issues and save construction time and labor costs, by:
• Reducing Steel and Concrete Volumes
• Improving Concrete Pouring Efficiencies
• Lowering Rebar Placing Costs
• Reducing Placing Time
• Lowering Cage Weights
• Saving on Couplers
• Improving Jobsite Transit, Storage and Logistics
Corrosion Protection: 100+ Years of Service Life
ChrōmX 9000 reinforcing steels have been independently proven to exceed the 100-year service life without repair requirement that is now being specified in bridge and infrastructure projects by many DOTs and public agencies in North America. Forward thinking owners are realizing that historical rebar options are not standing the test of time in corrosive environments and they are working to avoid the burden of high maintenance costs. Solid stainless steel rebar can also meet this lifetime requirement but the higher price is seldom justified when ChrōmX 9000 rebar provides the 100+ year solution at significantly lower costs.
Smart Money – Life Cycle Cost
Prudent owners and experienced design and construction professionals look at more than just the initial cost of materials when deciding on the best reinforcing steel options. Using life cycle cost analyses, many public agencies and private owners have found that using better materials, such as ChrōmX 9000 rebar, can save them and their taxpayers millions of dollars in future maintenance and rehabilitation costs when compared to standard or epoxy coated rebar. It does not take a lifetime to realize these savings. The benefits of ChrōmX 9000 are realized in the first 20-30 years when repairs would be required if traditional rebar products were used.
No Special Handling Requirements
Uncoated ChrōmX 9000 provides all of its corrosion protection benefits without the labor intensive special handling requirements, field coating inspections and repairs, or special fabrication needs of coated rebar. The ductile high strength nature of ChrōmX 9000 steels allows the rebar to be cut and bent using standard fabrication equipment and accepted industry practices. ChrōmX 9000 steels feature all the ease of construction found in standard grade black bar – with all the benefits and superior performance of a technically advanced product.

The ChrōmX Family
ChrōmX 9000 Series, together with ChrōmX 4000 and 2000 steels, provide high strength with varying levels of corrosion resistance, so designers can utilize the high strength efficiencies and best match the corrosion protection requirements of a given project. All three Chrōmx steels can be used together to build quality structures most efficiently.
