Product Overview
Galvanised mini joist hanger engineered to fit 47mm-wide timber - the finished size of standard 50mm nominal sections typically used in C16 or C24 structural grades, such as 47 × 100mm joists.
Manufactured from galvanised steel for light-duty timber-to-timber connections, it provides a compact and durable solution for fixing small joists, trimmers, or noggins.
The galvanised zinc coating offers effective corrosion protection, extending service life in internal environments. Precision-formed flanges and pre-punched nail holes ensure consistent alignment and secure bearing contact between connected timbers.
Ideal for use with joists up to approximately 100mm deep, the 47mm width accommodates standard small-section timbers with an accurate, snug fit.
The 67mm hanger height ensures adequate bearing surface while maintaining a low visual profile for concealed or secondary framing uses.
Features & Benefits
- Material specification: Galvanised steel manufactured to BS EN 10346 DX51D + Z275 for corrosion resistance and long-term reliability in indoor timber structures.
- Structural form: Light-duty design suitable for small-span timber members, ensuring reliable support without excessive weight or projection.
- Pre-punched fixing holes: Allows secure fastening using 30 × 3.75mm square-twist nails or equivalent, ensuring full mechanical engagement with the supporting timber.
- Compact bearing depth: Provides an effective bearing seat of approximately 40-50mm, allowing efficient load transfer between joist and supporting member.
- Corrosion protection: Hot-dip galvanised finish resists oxidation and moisture, extending service life under normal interior exposure conditions.
Applications
- Ceiling joists: Used for light-duty joist fixing in ceilings where space and visual neatness are priorities.
- Timber trimmers: Suitable for connecting short trimmer joists around ceiling openings or hatches.
- Partition frames: Ideal for constructing internal studwork or timber partitions using narrow timber members.
- Light decking: Applied in lightweight decking or platform structures where minimal load-bearing is required.
- General timber joinery: Effective for small structural links where standard joist hangers would be oversized or visually intrusive.
Installation Guidance
- Preparation: Ensure both the main and supported timbers are square-cut, dry, and free of debris before fixing.
- Positioning: Fix the hanger so the 67mm height runs vertically and the 47mm width matches the supported joist width.
- Fixing: Use 30 × 3.75mm square-twist nails (or approved equivalent) through all pre-punched holes in both the hanger flanges and seat.
- Joist seating: Insert the joist fully into the hanger so it bears firmly on the base and fits flush against the back flange.
- Alignment check: Verify the hanger and joist remain level and square before loading or securing additional framing.
Compliance & Performance
- Material grade: Galvanised steel to BS EN 10346 DX51D + Z275, meeting requirements for corrosion-resistant construction fittings.
- Load rating: Typical safe working load of approximately 3.47 kN for timber-to-timber connection when fully nailed to specification.
- Quality assurance: Produced under certified manufacturing control for consistent geometry and pre-punched accuracy.
- Important note: Designed for light-duty timber framing only - not for primary load-bearing or structural joist support. All fixing holes must be filled with approved nails to achieve rated performance.
