Ultra-High Tensile (UHS) Strand

*UHS strand needs epoxy
coating for employment.

Ultra-High Tensile Strength (UHS) Strand has approximately 20% higher strength than that of conventional PC strand. It can achieve shortening construction period and saving construction materials to bring in reduction saving not only cost but environmental loading. Projects applied UHS strand is gradually increasing reflecting current needs of the industry.
