Corrugated wall ties are the fundamental component used to tie a masonry veneer (such as a brick or stone façade) back to its structural backing, typically wood or steel framing. These ties are designed to transfer lateral loads, like wind pressure, and to accommodate slight differential movement between the two wall systems, ensuring long-term stability, safety, and structural integrity. Their distinctive "wavy" or corrugated shape is key to their performance, providing superior mechanical grip within the mortar joint. The unique corrugated design creates a powerful "keying" action within the hardened mortar. This mechanical lock is far more effective than a smooth tie at resisting pull-out and shear forces, ensuring a robust connection that lasts the lifetime of the building.
