Shot Fired to Steel Girders Masonry Joist Hanger JHMI

The Simpson Strong-Tie JHMI Masonry Joist Hanger range is an engineered family of heavy-duty connectors uniquely configured to facilitate direct mechanical fixing to structural steelwork headers. While carrying the core architectural advantages of the standard masonry profile, the JHMI configuration is optimised for shot-firing steel pins or deploying targeted self-tapping fasteners straight into steel girders, beams, and columns. This establishes a high-capacity, rigid joint interface that seamlessly bridges structural steel frames with timber floor layouts, saving substantial installation time on-site by removing the need for traditional timber packing pieces or complex masonry infills.

Optimised Steelwork Integration

Specifically configured with a modified top flange designed to handle the high thermal and mechanical stress of shot-fired installation pins, creating a direct, secure connection path into heavy steel framing elements.

Elite Structural Stability

Formed from premium pre-galvanised steel sheets providing superior shear resistance and durable side-flange alignment to eliminate joist rotation, maintaining structural integrity across open-plan floor drops.
