Generic 16 Gauge Hoop Iron, 20kg Galvanized Steel Roll

Galvanized Steel Hoop Iron

The 16 Gauge Hoop Iron provides essential structural reinforcement for masonry and timber assemblies in residential and commercial construction. This 20kg roll consists of high-tensile galvanized mild steel, offering the durability required to withstand the alkaline environment of cement mortar. Contractors rely on this specific gauge for securing wall plates to masonry and for general timber-to-timber connections on the job site.

Built for the Job

Site supervisors specify this material for critical load-path continuity in structural framing. It acts as a primary tension tie, preventing uplift in roofing structures during high-wind events by anchoring rafters directly to the wall mass. The 1.6mm thickness provides a balance of flexibility for shaping around timber members while maintaining the rigidness necessary to resist stretching under significant structural loads.

• Tying roof rafters or trusses down to the wall plate to resist wind uplift.

• Reinforcing masonry wall junctions and corners to prevent structural cracking.

• Bracing timber frames or temporary formwork during concrete pours.

Product Highlights

Structural Integrity

The 16-gauge thickness provides high tensile strength for lateral stability in blockwork and timber framing applications.

Corrosion Resistance

• Hot-dipped galvanization prevents oxidation when embedded in wet mortar or exposed to cavity moisture.
• Zinc coating ensures long-term performance in external wall cavities and coastal environments.

On-Site & Workshop Notes

• Ensure the steel strapping is embedded at least 150mm into mortar joints for maximum pull-out resistance in masonry.

• Use galvanized nails or screws when fixing to timber to prevent galvanic corrosion between dissimilar metals.

• Always wear heavy-duty leather gloves when unrolling and cutting, as the sheared edges of the strip are extremely sharp.

• Maintain a minimum overlap of 150mm when joining two sections of strapping together to ensure structural continuity.

• Store the coil in a dry, covered area to prevent white rust formation on the zinc coating before installation.
