China's epoxy coated steel bars adopt national standards GB/T 25826-2010 and Ministry of Housing and Construction standard JG/T 502-2016 (replacing JG 3042-1997). American standards are ASTM A775/A775M and ASTM A934/A934M, and British standard is BS ISO 14654. The whole life cycle analysis shows that the comprehensive cost of epoxy coated steel bar is very low. Epoxy coated reinforced concrete structures have a longer life than ordinary carbon steel concrete structures. The coating of the bar has anti-permeability, so it can delay the corrosion medium (such as water, oxygen, chloride, etc.) contact with the steel, so that its corrosion resistance life is greatly extended.
