What is Decking Bracketry
Deck frame connectors (or decking bracketry) are heavy-duty metal components—such as joist hangers, angle clips, post bases, and tension ties—used to mechanically fasten timber or metal subframes together.
Unlike standard wood screws or nails (which rely purely on friction and can shear over time under lateral loads), structural deck bracketry transfers weight loads directly through engineered steel plates. This prevents subframe sagging, timber splitting, frame twisting, and structural collapse under heavy use.

The Benefits of Decking Bracketry & Subframe Connectors.
• Superior Structural Safety & Load Bearing: Connectors transfer heavy weight directly through engineered steel plates rather than relying on the friction of screws or nails. This prevents sagging, sway, and dynamic load failures (e.g., under heavy hot tubs or large gatherings).
• Wood Rot Prevention: Post base connectors elevate vertical support posts 25mm–50mm off wet soil or concrete, stopping ground-moisture absorption and extending subframe lifespan.
• Corrosion & Weather Resistance: Made from Hot-Dip Galvanised (Z275/Z350) or Grade 316 Stainless Steel engineered specifically for severe damp weather and UK climate conditions.
• Eliminates Split Timber & Creaking: Avoids angle-screwing (“toe-nailing”) into fragile end grain, preventing wood split during build and eliminating frame twisting/creaking over time.
• Full Code Compliance: Simpson Strong-Tie® hardware is fully load-tested to meet UK building regulations and structural compliance standards.
Technical Specifications & Compliance

FAQs
While you can join timber using screws, relying solely on screws (often called toe-screwing) creates weak shear points susceptible to snapping under dynamic loads, soil shifting, or wood expansion. Using structural decking bracketry transfers weight through tested steel connections, guaranteeing structural compliance and long-term frame safety.
For outdoor timber decking, you should always select Hot-Dip Galvanised (HDG) or Z275 / Z350 Pre-Galvanised Steel brackets. If installing near coastal areas or around saltwater pools, Grade 316 Stainless Steel bracketry is strongly recommended to prevent saltwater corrosion.
Timber posts buried directly in dirt or saturated concrete act like sponges, wicking moisture upward and rotting within 3–5 years. Post base connectors keep the timber elevated 25mm–50mm above the ground or concrete base, allowing water to drain away freely and keeping the post dry and structural for decades.
Simpson Strong-Tie is the global benchmark for structural timber connectors. Every Simpson Strong-Tie bracket supplied by F.H.Brundle undergoes rigorous physical load testing, meeting European and UK building regulations for structural load, sway resistance, and corrosion endurance.
