Decorative Rigid Ties and Knee Braces

Decorative Rigid Ties & Knee Braces for Heavy-Duty Outdoor Framing

Decorative rigid ties and knee braces from Simpson Strong-Tie are built for projects that demand serious structural strength, without sacrificing style. These connectors reinforce key intersections between beams and posts, particularly where angled or lateral forces are at play, making them essential for larger structures like pavilions, covered patios, or custom timber frames.

Part of the Outdoor Accents® line, these components feature the same black powder-coated finish and ZMAX® galvanized steel construction, making them visually consistent and corrosion-resistant for exposed outdoor builds.

What Do Rigid Ties and Knee Braces Do?

Rigid ties are used to secure beams to posts at perpendicular or angled joints, helping prevent twisting, shifting, and sagging under load. Knee braces add critical support and distribute stress at angled connections, especially in tall or open-sided structures where wind and weight can cause movement over time.

These aren’t just decorative. They're load-rated, engineered solutions that reinforce your frame and extend its long-term durability.

Why Builders Choose Simpson Decorative Rigid Ties & Knee Braces

• Load-Rated Strength: Tested and certified for structural applications in outdoor framing
• Architectural Appearance: Clean angles, bold lines, and black powder-coating for a polished finish
• ZMAX® Galvanized Steel: Resists corrosion in moisture-heavy or pressure-treated environments
• Perfect Compatibility: Works seamlessly with other Outdoor Accents hardware and fasteners

Best Applications for These Connectors

• Large pergolas, pavilions, and patio covers
• Custom timber frame structures
• Outdoor kitchens or gazebos with roof framing
• Posts subject to lateral loads or uplift
• Exposed framing where angled joints require added support and style

Installation Tips

Simpson knee braces and rigid ties install using matching SDWS or SD Connector Screws and optional hex-head washers. Ensure beam and post faces are flush before fastening to maximize surface contact and structural stability. When installed correctly, these components both secure and highlight the craftsmanship of your build.
