With vast experience of more than a decade we have developed a better understanding of the Post-Tensioning cables. Considering the complexities of the critical raw materials involved, we have established our own extrusion plant to produce PE Coated Post-Tensioning Cables which are used construction of concrete structures.
We follow a rigorous process of procurement, extrusion and testing of the PE Coated Post-Tensioning Cables. Our facility consists an exhaustive package for extruding the plastic sheathing over the bare strand, cutting-line and workstations to prepare the anchorage system ready to install at site.
