Simpson Strong-Tie Joist Hanger for Masonry

High-Performance Masonry Joist Hanger for Solid, Trussed, and Engineered Joists

The Simpson Strong-Tie JHM and JHMI range of masonry joist hangers is engineered to provide strong, secure, and code-compliant support for solid sawn joists, trusses, and engineered timber members connecting to masonry walls or steel beams. With enhanced flange geometry and performance-enhancing features, these hangers offer optimal structural support in load-bearing wall applications.

Key Features

• Wide Top Flange Contact
  The top flange provides the maximum surface area contact with masonry, improving mortar adhesion and overall load performance.

• Tall Side Flanges on Deeper Hangers
  Taller than traditional designs, the side flanges offer increased resistance to joist rotation, particularly beneficial for longer or heavier joists.

• Inspection Slot
  A built-in slot at the base of the hanger allows for easy visual inspection from ground level—streamlining compliance checks during or after installation.

• Embossed Stiffening
  Reinforcing embossments and pre-punched holes in the top flange enhance structural rigidity and allow improved mortar keying during block or brickwork installation.

• Multiple Configurations Available

  • JHMR: Return configuration for masonry returns

  • JHMS: Straddle configuration for block wall cross-sections

  • JHMSK: Skewable option for angled joist installations

Benefits

• Reliable Masonry Fixing
  Specifically designed for integration with brick or block walls, ensuring dependable load transfer and long-term support.

• Reduces Joist Movement
  Side flange design minimises rotational deflection in deeper joist connections, preserving structural integrity.

• Versatile Applications
  Supports a wide range of joist types and construction configurations, including skewed and straddled layouts.

• Durable Construction
  Made from pre-galvanised mild steel, offering corrosion resistance suitable for protected internal masonry environments.
