A helical tie is produced by twisting a metallic profile into the shape of a helix. The design on the Simpson Potent-Tie Heli-Tie wall tie also incorporates a large core diameter in an effort to present bigger torsional capacity. The benefit of this characteristic is considerably less axial deflection as a consequence of a propensity for normal helix shape to “uncoil” below stress load.
Yet another indicator to watch out for is cracking during the masonry of window reveals. As the rust builds up around the wall tie the power designed cracks the window reveals that have significantly structurally susceptible edges.
