Simpson Strong-Tie Heavy Masonry Hanger for I-Joists and Metal Web Joists-1234

High-Capacity Hanger for Engineered Timber to Masonry and Steel Connections

The Simpson Strong-Tie HJHMI range is purpose-built to connect engineered I-joists, metal web joists, solid sawn timber, and trusses directly to masonry walls or steel beams. Designed for heavy-duty applications, this hanger combines robust performance with precision detailing to meet the demands of modern structural timber construction.

Key Features

• Engineered for High Loads
  The HJHMI hanger delivers superior load-bearing performance, making it ideal for critical joist-to-masonry or joist-to-steel installations.

• Extended Top Flange
  The top flange spans a wide area for increased surface contact with masonry, improving structural stability and load distribution.

• Deep Side Flanges
  On deeper hanger models, side flanges are significantly taller than traditional hangers, helping prevent joist rotation under load.

• Inspection Slot
  A built-in slot at the base allows for visual inspection from ground level, supporting easier site checks and regulatory compliance.

• Mortar Keying Embossments
  Stiffening ribs and perforations in the top flange improve bond with mortar, ensuring secure masonry integration.

Benefits

• Ideal for I-Joists & Web Joists:
  Suitable for both traditional solid timber and engineered timber systems including metal web joists.

• Pre-Galvanised Protection:
  Made from pre-galvanised mild steel for enhanced corrosion resistance in indoor and sheltered outdoor applications.

• Reduces Rotation & Deflection:
  Taller side flanges deliver lateral stability to joists, especially important for longer spans and engineered timber.

• Meets Structural Standards:
  Designed in line with high-performance masonry fixing requirements and compatible with various timber joist depths and widths.
