The Simpson Masonry Brick Reinforcement Mesh you mentioned is designed for enhancing the tensile strength of brickwork. Here are some key details:

• Dimensions: 112mm x 20m
• Material: Galvanised steel, which provides excellent corrosion resistance
• Weight: Approximately 1kg
• Usage: Typically installed in the mortar course during construction to increase tensile strength and resist local cracking, especially around wall openings
• Installation: Coiled for ease of handling, it should be laid every third brickwork course for most reinforcement applications

This mesh is a great choice for ensuring the durability and stability of masonry structures.
