Achieves excellent adhesion performance, rust prevention performance, and fatigue resistance performance! A method that allows for free re-tensioning.
The "SC Strand & KTB Anchorage Method" uses SC strands, which are PC steel wires with a full wire coating, as the tensioning material and employs both wedges and nuts for anchoring. "SC Strand" is formed by thermally fusing epoxy resin powder coating onto each core wire and side wire of the PC steel wire using an electrostatic powder coating method, achieving complete rust prevention. The film thickness is between 120 and 280 µm, allowing for direct attachment of crimp grips and demonstrating excellent anchoring performance. 【Features】 - Eliminates set loss during anchoring, allowing for free re-tensioning - High durability - Excellent anchoring performance - Superior fatigue performance - Reduction in construction costs For more details, please refer to the catalog or feel free to contact us.
