100mm Galvanised Brick Reinforcement Coil 20m

Galvanised brick reinforcement coil with a 100mm width and 20m length. Manufactured from cold-formed, zinc-coated steel, this coil provides continuous bed-joint reinforcement in brick and block masonry. It delivers tensile strength across mortar joints, reducing the risk of cracking caused by shrinkage, settlement, or thermal movement. The coil unrolls cleanly and lies flat within a standard 10mm mortar bed, ensuring precise alignment without curl or distortion. The galvanised coating offers dependable corrosion resistance, making it suitable for internal and sheltered external use. For structures in exposed or marine environments, stainless steel reinforcement is recommended. Compatible with all common masonry units and mortar types, the coil is a practical solution for strengthening walls at openings, junctions, or areas of concentrated stress. By spreading loads evenly through the joint, it maintains structural integrity and preserves the visual continuity of the brickwork. The 100mm width is designed for use in walls of approximately 140mm (e.g. medium-gauge block or cavity leaves), maintaining 20mm mortar cover to both faces for secure embedment and lasting performance.
