Super Galvanising has launched its first continuous galvanizing rebar (CGR) line at its operations in Dubai.

CGR is a new process for protecting steel reinforcing bar (rebar) used in concrete. Using a zinc coating, CGR provides superior corrosion protection for concrete structures at significant cost savings, a statement said.

Adding a small amount of aluminum (0.2pc) to the zinc bath, the CGR coating process produces a coating that is almost pure zinc and adheres very well to the steel enabling the coated bar to be bent, without cracking or flaking of the coating. All grades of steel including normal and high strength steels can be galvanized, it said.

The CGR process is very similar to continuous galvanized sheet steel. The steel bars are immersed only a few seconds in the zinc bath resulting in a high-quality coating that provides excellent corrosion protection and very formable coated bars that can be bent to tight radii.

“Our new line is producing continuously galvanized rebar that is a superior product with several key technical advantages and that is a lower cost than other alternatives.  This product will set the standard for corrosion resistant rebar in concrete structures,” said Steven Quah, CEO of Super Galvanising.

The CGR process has recently been developed with support from International Zinc Association.  CGR meets ISO 14657 “Zinc Coated steel for the reinforcement of concrete”, the statement said. - TradeArabia News Service
