About LANDIS THREADING MACHINE
What is a LANDIS Threading Machine?
A LANDIS Threading Machine is a high-precision industrial machine used to create threads on:
- TMT bars
- Steel rods
- Pipes
- Bolts
- Fasteners
The machine uses special LANDIS threading dies/chasers to cut or roll accurate threads for mechanical coupler systems. These threads are later connected using rebar couplers for RCC construction.
LANDIS machines are highly popular in:
- High-rise construction
- Bridge projects
- Metro rail projects
- Industrial fabrication
- Infrastructure development.
