Since then, other rebar alloys have become commercially available which possess enhanced corrosion resistance and improved mechanical properties.

That is 2.5 times the service life of the bridge it is replacing! As engineering standards and practices may differ between continents, both a European as well as a North America oriented version are available. Find and evaluate OEMs, Custom Manufacturers, Service Companies and Distributors. This makes bar length important. Several bridges in continental Europe and the UK were built or repaired using stainless steel rebar in the period late 1960s to early 1990s. Stainless Type 304LN is a nitrogen-strengthened version of stainless Type 304L available in the hot rolled condition. (Photo 1) In addition, all four alloys have good toughness and fatigue resistance. hbspt.cta._relativeUrls=true;hbspt.cta.load(7407324, '563c1169-51c9-4064-8caa-3c0ae8ae28fa', {"useNewLoader":"true","region":"na1"}); As our top value, we're proud to create a culture of safety in everything we do.

Saskatchewan River Br., Medecine Hat, Alberta, Steinhauser Bridge, Hwy 63, Ft. McMurray, Alberta, STAINLESS STEEL REINFORCEMENT: THE ROLE OF NICKEL, Welded wire mesh (produced to ASTM A1022). Since the defect usually cannot be seen or found in the concrete, the bar can seriously deteriorate, shortening the life of the structure in which it is used. As the rust produced has a greater volume than the steel, it causes the concrete to crack which in turn allows more salt-laden water to penetrate faster and deeper into the concrete structure. SSR is dedicated entirely to the fabrication of stainless steel rebar. This selective substitution can greatly extend the service life of the structure.Deeper within the concrete structure, where corrosive agents are unlikely to penetrate, stainless steel rebar is not required. A coastal replacement bridge currently under construction at North Bend, Ore., graphically demonstrates the benefits of using 2205 stainless steel rebar instead of carbon steel rebar for critical structural elements in a harsh marine environment. Stainless Type 316LN offers low magnetic permeability, which is essential for rebar that could be used in structures close to sensitive electronic devices or magnetic resonance medical equipment. SSRs experience and products embodies a solution to owners, operators, designers or specifiers of concrete structures faced with solving the problem of deteriorating concrete caused by chloride attack of the steel rebar from road salt, marine spray or other chemical agents. A number after X represents the 100 times the carbon content.
