PC Strand
Epoxy Resin Coated Strand
Nominal diameter: 12.70mm, 15.20mm
Coil weight: 2.5-3.5 tons
Grade: 250/270
Application: Epoxy coated strands are mainly used for prestressed external tendons, stay cables, prestressed piling, PC pavement, rock and soil anchors, etc.
As a new type of prestressed material, epoxy-coated prestressed steel strands have been widely used in bridge engineering with their excellent anti-corrosion properties, involving stay cables, external cables, internal cables, suspender cables, tie-rod cables, rock and soil anchor cables.
Epoxy coating filled steel strands with an average epoxy coating thickness of 0.6～0.8mm. It uses special surface treatment technology and high-voltage electrostatic spraying method to form a uniform on the steel bar matrix. There is a certain thickness of epoxy resin anticorrosive layer, which makes the physical and chemical properties of the product stable, and has the characteristics of heavy corrosion resistance, acid resistance, alkali resistance, salt resistance, temperature resistance, and insulation.
