Cavity ties are usually made of sturdy materials such as stainless steel or galvanized steel, ensuring they possess the necessary strength and resistance to corrosion. These ties are designed to span the cavity space between the two leaves of a wall, thus maintaining alignment and stability. Depending on the specific construction needs and environment, cavity ties can vary in length, shape, and configuration. The most common types include the horizontal, vertical, and angled cavity ties, each serving particular structural requirements.
