Cryogenic Rebar

CryoSTEEL® is a specially-engineered concrete reinforcing steel produced by CMC for cryogenic applications.

CMC's cryogenic rebar is designed to resist the extremely low temperatures that liquified natural gas (LNG) tanks and other cold climate applications experience. This innovative cryogenic reinforcing steel can improve and streamline how LNG tanks are designed and built in the future.

CMC's advanced production process for CryoSTEEL® yields results that exceed minimum specifications and published temperatures of other cryogenic steel producers, while still meeting all strength and ductility specification requirements. This additional safety factor provides peace of mind when designing and building liquified natural gas tanks and other concrete structures using cryogenic rebar that will be exposed to extreme environments and temperatures.

CryoSTEEL® has been successfully tested down to -265°F (-165°C) by an independent lab to ensure this cryogenic rebar meets or exceeds all specifications for the majority of cryogenic applications. CMC will individually test CryoSTEEL® to the required design temperature for the cryogenic steel in your specific LNG tank or project need.



Shorter Lead Times - Domestically produced in the U.S. means shorter lead times. Historically, cryogenic rebar has only been available from international sources.

No more ordering overages - Order exactly the cryogenic steel your job requires and have CMC deliver installation-ready rebar directly to your job site.

Reduced logistics frustrations - Removes the need to manage separate purchasing, storage and fabrication processes - simplify your project by partnering with CMC and reduce the extra headaches of cryogenic requirements.

Higher Specs/Lower Temperatures - Exceeds minimum design specifications for cryogenic steel as a result of the advanced production process.



CryoSTEEL® rebar is produced in imperial units and is available in lengths up to 66 feet.

Available in two specifications to meet a wide range of cryogenic temperature requirements, CryoSTEEL® rebar is produced in the following grade, sizes and specifications:

  • ASTM A615 Grade 60 (60,000 PSI/420 MPa)
  • Rebar #4 (13mm), #5 (16mm), #6 (19mm), #8 (25mm), #9 (29mm), #10 (32mm)
  • CryoSteel-58: designed for LPG tanks or other structures exposed to temperatures down to -58°F (-50°C)
  • CryoSteel-265: designed for LNG and ethylene tanks or other structures exposed to temperatures from -58°F down to -265°F (-50°C to -165°C)


With CryoSTEEL® you are assured that all specifications for cryogenic rebar are met through rigorous testing with certifications issued for each heat delivered.

Testing is performed to ACI 376-11 "Code Requirements for Design & Construction of Concrete Structures for Containment of Refrigerated Liquefied Gases" and BS EN 14620-3:2006 Annex A.3 for reinforcing steel for the "Design and manufacture of site built, vertical, cylindrical, flat-bottomed, steel tanks for the storage of refrigerated, liquefied gases with operating temperatures between 0 deg. C and -165 deg. C. Part 3: Concrete Components."

CryoSTEEL® is produced exclusively at our CMC Steel Arizona mill. For additional information about CMC's cryogenic rebar, contact a sales representative at 888.641.8956 or email us at
