Epoxy coated unbonded strand is a steel wire product used in construction, bridge and road works. It is made of multiple steel wires stranded together, and after special treatment, the surface is coated with an epoxy resin coating to form an unbonded structure. This unbonded structure makes the strand more wear-resistant, corrosion-resistant, oxidation-resistant and can be used in a wide range of temperatures. It also has a longer service life than strands with traditional bonded structures. Epoxy coated unbonded strand has a wide range of applications and is commonly used in bridges, highways, buildings, mines, marine engineering and other fields.
