The Simpson Strong-Tie HJHMI Heavy Duty range is a series of structural-grade masonry supported joist hangers engineered specifically to accommodate deep, high-capacity engineered wood I-joists. Formed from robust 3mm thick pre-galvanised mild steel, these heavy-duty connectors provide a rigid, reliable interface for transferring heavy floor loads directly into supporting blockwork or structural steel beams. By supplying exceptional vertical shear capacity and side-flange restraint, this system effectively supports deep-set engineered timber layouts across wide-span intermediate floors, apartment separation zones, and demanding commercial developments.

Engineered I-Joist Containment Features extra-high side flanges configured to provide excellent lateral containment for deep I-joist profiles, keeping the slim internal web fully stabilised and highly resistant to structural rotational forces. |
Elite Load Bearing Interface Includes an expanded top flange layout that optimizes surface contact area with masonry structures to ensure safe downward load distribution, whilst featuring a base slot to assist rapid ground-level tracking and inspection. |
