SC Pile Stud Method

SC Pile Stud Method (GBRC Performance Certification #12-19) is a pile head joint method by which Pile Stud Deformed Bar can be welded to SC Pile which is equipped with a size larger end plate (widen plate) than pile diameter. In 2012 we were granted Construction Technology Performance Certification from General Building Res. Corp. or GBRC.
SC Pile Stud Method can reduce man hour because of shorter welding time as compared with general flare welding method and can reduce damage to pile.

Characteristics

  1. Man hour can be reduced greatly because of shorter welding time per one reinforcement bar.
  2. Damage to pile is small because of little heat input as compared with conventional method (flare welding).
  3. Construction carrying-out soil is less because of small excavation area around pile head.
  4. Steady welding quality can be secured because of clear quality control standard.
