Stainless steel rebar uses for concrete reinforcement are rising globally. The enhanced properties of stainless steel prove to be a viable solution when life cycle costs of the structures are taken into account. Austenitic (a.k.a. 300 series, the most common type) and duplex (higher-strength, comparable corrosion resistance) stainless steels are used as rebar because they present an excellent combination of corrosion resistance in concrete, high strength and good ductility.
Stainless steel rebar uses include highway bridges, parking garages, coastal facilities and many other structures. Some installations date back some 20 years – one marine structure has a service history of 60 years! In addition to superior corrosion resistance, stainless steel rebar uses involve conditions that require non-magnetic materials. This can entail certain military, medical and scientific applications – like hospitals with MRI machines.
In addition to these, stainless steel rebar uses can extend to just about any structure. This is because of stainless steels advantageous properties. Its ductility and strength make stainless steel rebar use in earthquake-prone areas an asset, and even more impressive is the fact that it can retain these properties even in cryogenic temperatures!
The world is taking notice. Stainless steel rebar uses in North America have risen tremendously even in the past few years. Nearly 400 tons of duplex stainless steel rebar was supplied for the Haynes Inlet Slough Bridge, near the coastal town of Coos Bay, Oregon (USA). Apparently, this modern bridge has more stainless steel rebar use than any North American bridge. The bridge is situated in a corrosive oceanic environment and was finished by the end of 2003 at a price tag of approximately $12 million.
For years to come stainless steel rebar uses in bridges, barrier walls and decking will steadily increase, not only to extend the life of critical areas of roadways and marine structures, but also to further civil innovation and maintain the level of confidence in infrastructure that we have today.
