Equipments And Installation
The self drilling hollow bars are typically installed using rotary percussive drilling. Drilling and Grouting are simultaneous.
- ISO 9001 Quality Management System
- IBO hollow bar products sampling and inspection:
Initial examines: Dimension, Appearance inspection (Raw material steel pipes)
Duplicate examines: performance inspection(IBO hollow bar strength and ductility)
Finished bar examines: Dimension (100%), Appearance (100%) and Tensile Test (3%)
Finished bar examines
