Simpson Strong-Tie: Structural Connectors for Safer, Stronger Builds

For over 60 years, Simpson Strong-Tie® has focused on engineering connectors that perform under the toughest conditions — helping builders create safer, stronger homes and structures. With more than 1,000 product solutions, Simpson Strong-Tie offers one of the widest structural connector ranges available in the UK and Europe, all engineered for strength, durability, and compliance with current building codes.

What Simpson Strong-Tie Covers

• Joist hangers & framing connectors — for timber-to-timber, timber-to-masonry, and steel-to-steel connections, including height-adjustable hangers (e.g. the JHA range) for fast, accurate on-site fitting.
• Restraint straps — light and heavy-duty straps (flat, bent, or twisted) for tying timber floor and roof systems back to masonry walls.
• Fasteners — performance-tested nails and screws for structural framework, decking, cladding, and flooring, including the Quik Drive® collated screw system for fast, jam-free installation on wall, floor, and ceiling fixings.
• Mechanical & chemical anchors — for fixing into masonry and concrete.

Deck Frame Connectors

Simpson Strong-Tie is the go-to partner for building a strong, long-lasting deck substructure. Deck frame connectors — post bases, joist hangers, and angle brackets — transfer load correctly between joists, beams, and posts, which is critical for both structural safety and building-code compliance. Key things to get right on any deck subframe:

• Bearing & fixing: hangers must be installed with the correct fastener type and quantity per the published technical data sheet — undersized or substitute fixings reduce the rated load capacity.
• Gap tolerance: joist hangers are tested (and rated) with a small, consistent gap between the joist end and the header — larger gaps in the field reduce the achievable load versus the published figures.
• Timber grade: connector load ratings assume a stated timber grade and moisture condition; always check the product’s technical data sheet for the specific grade used on site.
