Tie Rod Scaffolding

A Tie Rod is a high-strength threaded rod used in formwork and scaffolding systems to hold and secure wall formwork panels together during concrete pouring. It resists the horizontal pressure of fresh concrete, ensuring the formwork remains stable and aligned. NOVSA manufactures Tie Rods with precision threading and superior material quality to provide maximum load-bearing capacity and long service life.
