Reinforcement Coil – Galvanised Steel – External Masonry

Product Overview

This 100mm galvanised brick reinforcement coil, measuring 20 meters in length, is crafted from cold-formed, zinc-coated steel. It is designed to provide continuous bed-joint reinforcement in brick and block masonry. The coil enhances tensile strength across mortar joints, mitigating the risk of cracking due to shrinkage, settlement, or thermal movement. It unrolls smoothly and lies flat within a standard 10mm mortar bed, ensuring precise alignment without curl or distortion.

The galvanised coating offers reliable corrosion resistance, making it suitable for internal and sheltered external applications. For structures in exposed or marine environments, stainless steel reinforcement is recommended. This coil is compatible with all common masonry units and mortar types, providing a practical solution for strengthening walls at openings, junctions, or areas of concentrated stress. By distributing loads evenly, it preserves structural integrity and visual continuity of the brickwork.

Features & Benefits

• Tensile control in bed joints: Enhances horizontal tensile capacity to resist cracking from shrinkage and thermal movement.
• Galvanised protection: Zinc coating ensures corrosion resistance in internal and low-exposure conditions.
• Continuous roll format: The 20m coil minimizes joints, waste, and installation time on extended runs.
• Easy to cut and form: Can be cleanly cut with snips or shears; lays true without distortion.
• Compatible with common mortars: Suitable for cement-lime and masonry cement mixes at 10mm bed thickness.
• Consistent edge cover: Ensures a minimum of 20mm mortar cover on both faces for full embedment.
• Defined width: 100mm width is ideal for walls of approximately 140mm or greater thickness, ensuring proper cover.

Applications

• Crack control at openings: Reinforces above doors and windows to reduce horizontal cracking.
• Movement management in long runs: Maintains tensile continuity across extended wall sections.
• Junction reinforcement: Strengthens returns, partitions, and intersections within bed joints.
• Local reinforcement: Supports areas around chases, service penetrations, or concentrated loads.

Installation Guidance

• Prepare the bed: Lay a full, even 10mm mortar bed; ensure surfaces are clean and well supported.
• Position centrally: Place the coil mid-depth of the bed, maintaining alignment.

FAQ

Q: Can this reinforcement be used in marine environments?
A: While the galvanised coil is suitable for internal and low-exposure conditions, stainless steel reinforcement is recommended for marine environments.

Q: What is the recommended mortar bed thickness?
A: A 10mm mortar bed is recommended for optimal performance and embedment.

Q: Is this coil compatible with all masonry units?
A: Yes, it is compatible with all common masonry units and mortar types.
