Exceptional Quality Stainless Steel Rebar

PRLog (Press Release) - Oct. 16, 2012 - Despite casting the rebars into the cement concrete, most of the buildings and structures weakens earlier than anticipated due to oxidation of rebars itself. This has become rather challenging both technically and economically. A recent survey showed that there are numerous countries all across the world who spends billion and billion of money every year in order to repair these decaying structures and buildings. Their report also showed some cases, where the whole structure was needed to be replaced because of oxidation rebars. All these repairs and replacement causes significant disturbance as well as hazards and monetary losses, which were considered as a big drawback to the country’s economy.

After manifesting research, it was concluded that the reason behind corrosion or oxidation of the rebars was its contact with chloride from water and deicing salt from the structure. It was inevitable for carbon steel rebars to easily corrode and rust from chloride and salt. Because of rust formation inside the structure, a brute force is created that exceeds the ductile strength of the concrete and hence, it result in cracking and crumbling of the building.

In order to address this situation, researchers started to work of the following strategies:

I.Develop dense cement concrete that prevent chloride and salt from entering the structure.
II.Create special coating for the concrete structure itself.
III.Confine corrosion with cathodic protection or chemical compound.
IV.Build non-metallic rebars.
V.Develop high corrosive resistant metal rebar.

After eliminating the expensive and unfeasible strategies, the researchers chose the fifth strategy of developing a high corrosive resistant metal rebar.

The only inexpensive and high corrosive resistance metal available in the market today was stainless steel. Stainless steel rebars were started to manufacture and they proved to be high corrosion resistant, which also had good strength and better ductile properties. Besides, they also had good high and low temperature mechanical properties, which made them ideal for any weather condition. These stainless steel reinforcing bar definitely cut down the life cycle costs for various buildings and structures.
