Formwork Tie Rods (also referred to as Tie Bars or Coil Rods, Z Bars) are critical to construction as they prevent the two sides of the Formwork (front and back) from separating and bulging due to outward pressure exerted onto the Forms by the wet concrete being poured. The Tie Rods are the fasteners that hold the two faces of formwork together to ensure that the walls stay at the correct thickness of the intended design.
Our industrial-grade formwork tie rod ensures a solid and dependable base for all the concrete that's being poured into your project. Designed specifically for long life and maximum capacity to bear loads, our tie rod will not yield to strain or deformation, making it ideal for high-rise commercial building projects or residential development. Incorporated with wing nuts and waterstops, our tie rods create an easy-to-assemble system.
