For underground utility tunnel construction, pipe and cable support is a critical part. Two mainstream solutions: welded support and prefabricated strut support (unistrut system).
Welded support requires on-site cutting, welding and anti-corrosion treatment. Quality is heavily affected by site workmanship, and modification is difficult after installation.
Prefabricated unistrut support is pre-fabricated in factory. All components are standardized and galvanized. Installation only uses bolts, no welding. It is adjustable, reusable and easier to meet seismic requirements.
Advantages of prefabricated strut support:
Faster site installation
Consistent anti-corrosion performance
Easy re-adjustment for layout changes
Better compliance with seismic bracing codes
For large utility tunnel, M&E and seismic projects, prefabricated strut channel systems are increasingly preferred by contractors and consultants. Senji Asia supplies complete utility tunnel bracket and unistrut support packages for global construction projects.
