Decorative T Straps and L Straps

Decorative T and L Straps for Structural Framing Connections

Simpson Strong-Tie’s decorative T and L straps bring strength, symmetry, and architectural polish to outdoor framing projects. Designed for visible applications like pergolas, pavilions, gazebos, and arbors, these connectors reinforce right-angle joints and beam intersections while adding a refined black powder-coated finish to your structure.

Made from ZMAX® galvanized steel and finished for corrosion resistance and style, these structural straps offer a clean, decorative way to join wood members and improve rigidity at key junctions.

What Are Decorative T and L Straps Used For?

T and L straps are used to brace and reinforce wood-to-wood connections, especially where beams intersect or turn at 90-degree angles. The “T” straps reinforce vertical post and horizontal beam connections, while the “L” straps provide corner support or angled bracing.

In decorative outdoor builds, these straps aren’t just for function, they help frame the structure visually and provide symmetrical focal points that elevate the overall design.
