Toughened Epoxy Resin Coated Steel Bar

The epoxy coated steel bars used in China adhere to national standards GB/T 25826-2010 and the Ministry of Housing and Construction standard JG/T 502-2016 (replacing JG 3042-1997). In the United States, the standards are ASTM A775/A775M and ASTM A934/A934M, while the British standard is BS ISO 14654. A comprehensive life cycle analysis demonstrates that the overall cost of epoxy coated steel bars is very low. Structures reinforced with epoxy coated steel bars have a longer lifespan compared to ordinary carbon steel concrete structures. The bar’s coating provides anti-permeability, effectively delaying the contact of corrosion mediums such as water, oxygen, and chloride with the steel, thereby significantly extending its corrosion resistance lifespan.
