Answering the call for enhanced corrosion protection of reinforcing steel that is also economically viable, SMI is proud to introduce SMI 316 SC™ stainless steel clad bars. This product combines the cost effective attributes of commonly specified ASTM A615 grade 60 carbon steel as the core with a metallurgically bonded outside layer of AISI 316 stainless steel, widely recognized for its superior corrosion protection.

SMI 316 SC™ clad bars are available in rebar sizes #4 (13mm) through #18 (57mm). They are also available as stock rounds in 1-1/4" and 1-1/2" diameters primarily used for concrete paving dowels (additional sizes available upon request).

SMI 316 SC™ clad bars utilize a patented spray metalizing process where conventionally melted and cast semi-finished steel billets are coated with an external layer of stainless steel. The stainless steel coated billet is transformed into finished products through traditional rolling mill practices.

Advantages of SMI 316 SC™ Clad Bars:

• Excellent Corrosion Protection - Initial laboratory tests indicate stainless steel clad bars will perform for up to 75 years or more.
• Made in the USA - Production and availability is local meeting FHWA "Buy American" requirements.
• Bond - Standard development lengths can be used for embedments and lap splice requirements as concrete bond is similar to "black bars."
• Additional Grades - The carbon steel core can be produced to different grades including ASTM A615 grades 40, 60 or 75, and ASTM A706. Alternative stainless steel coatings may be available upon request.

How to Specify

By Company: "Stainless clad steel as shown in the plans shall be SMI 316 SC as manufactured by SMI"

Generically: "Corrosion resistant steel shall be stainless steel clad with a minimum 7 mil coating of AISI 316. The carbon core is to be conventionally produced in an electric arc furnace meeting all requirements of ASTM A615 grade 60. The stainless steel coating shall be metallurgically bonded to the carbon core so that no debonding will occur during normal fabrication, handling or placing."
