The Simpson Strong-Tie WTS3-300 is a 300mm Type 3 stainless steel wire wall tie designed for general-purpose masonry-to-masonry connections. It provides lateral support across wider wall cavities ranging from 151mm to 175mm. This tie is suitable for domestic and small commercial buildings up to 15m in height, subject to specific wind speed limitations.
During the bricklaying process, the wall ties are embedded directly into the mortar joints of the inner and outer masonry leaves. A minimum embedment of 50mm is required on each side to maintain structural integrity, while standard site installations typically achieve between 62.5mm and 75mm. The standard installation density requires at least 2.5 ties per square metre, typically spaced at 900mm horizontal and 450mm vertical centres.
Made from austenitic stainless steel, the WTS3-300 provides inherent corrosion resistance to support long-term structural stability. As a Type 3 classification tie, it is suitable for use in flat sites with a fundamental basic wind velocity limited to 27m/s and an altitude up to 150m above sea level.
- Designed for cavity widths between 151mm and 175mm for exact specification.
- Made from austenitic stainless steel for high inherent corrosion resistance.
- Requires a minimum embedment of 50mm per masonry leaf for structural safety.
- Achieves a declared tensile load capacity of 1100N under standard testing.
- Suitable for buildings up to 15m high with wind speeds up to 27m/s.
