Wall Ties – Steel – Cavity Wall Construction

Product Overview

Our high-performance 200mm wall ties are designed for masonry cavity walls with a cavity width of 50–75mm. They provide secure restraint between masonry leaves while allowing for differential movement.

Classified as Type 4 ties to BS EN 845-1, they are suitable for dwellings up to 10m high in sheltered environments, typically where basic wind speed is below 27m/s. Their classification ensures they are perfectly specified for residential construction in low-exposure conditions.

Each tie features an indented profile to enhance mortar bond and provide effective wall stability. At 200mm, they are specifically proportioned for cavities of 50–75mm, ensuring correct embedment into both leaves of the wall.

Constructed from stainless steel, they are resistant to corrosion and offer a long service life without the need for replacement.
