COIL TIE SPRINGS
2 BAR STANDARD COIL TIE SPRINGS
Two (2) bars are welded to the coil tie springs which screw onto removable plastic cones to set the desirable width of the concrete wall to be formed. Coil tie bolts are screwed on either end to secure the wall shutters together. On completion, the coil tie cones are removed, leaving a neat hole in the concrete’s face.
4 BAR HEAVY DUTY COIL TIE SPRINGS
Four (4) bars are welded to coils giving greater strength than the two (2) bar springs. They are used to space coil ties in the concrete further apart, to use fewer coil ties in a wall and are ideal for matching an architectural pattern on the finished wall. Four (4) bar coil tie springs allow coil ties to be used as an architectural feature.
Coil Tie springs remain buried in the concrete, creating an effective water barrier.
