Product Description
The Simpson GT8Z ZMAX Galvanized Gazebo Tie Center for 8-2x Rafters is a purpose-built structural hub connector from Simpson Strong-Tie designed to unite eight 2x rafters at the top of an eight-sided octagonal gazebo. Fabricated from 18-gauge steel with a ZMAX galvanized finish, this gazebo tie delivers the corrosion resistance and structural integrity that engineers and contractors rely on for exterior wood framing and pressure-treated lumber applications. Engineered and tested to perform, it simplifies octagonal gazebo construction while producing a stronger, safer finished structure.
Key Features
- Connects eight 2x rafters at the top of an eight-sided gazebo - purpose-built geometry means the center hub connection is handled by a single, properly engineered component rather than improvised hardware.
- Designed for use as a pair - one above and one below the rafters - sandwiching the rafter assembly between two connectors locks the joint from both sides for a more secure, rigid center hub.
- Made from 18-gauge steel - provides the structural strength required for load-bearing rafter connections in outdoor gazebo framing.
- ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications - the heavy-duty galvanized coating stands up to outdoor exposure and the chemicals present in pressure-treated lumber, helping the connector maintain its integrity over time.
Why This Product
- Engineered specifically for octagonal gazebo construction - rather than adapting a general-purpose connector, the GT8Z is purpose-designed for eight-rafter center hub connections, making the build process more straightforward and the finished result structurally sound.
- ZMAX coating provides a meaningful upgrade in corrosion protection - for outdoor structures and projects using pressure-treated lumber, the extra galvanization helps the connector resist the elements and chemical exposure that would compromise a standard galvanized product over time.
- Backed by Simpson Strong-Tie engineering and testing standards - Simpson Strong-Tie connectors are the choice of engineers and contractors for a reason: each product is engineered, tested, and manufactured to meet rigorous quality standards, giving builders confidence in code-compliant structural connections.
- Made in the United States from 18-gauge steel - consistent domestic manufacturing supports reliable material quality and dimensional accuracy, which matters when eight rafters all need to meet cleanly at a single center point.

Frequently Asked Questions
- How many rafters does the GT8Z connect?
- The GT8Z connects eight 2x rafters at the top of an eight-sided gazebo, making it purpose-built for octagonal gazebo construction.
- How many GT8Z connectors are needed per gazebo?
- Two connectors are required per installation - one placed above and one placed below the rafters at the center hub connection point.
- What fasteners are recommended for installing the GT8Z?
- Installation requires (24) 0.148 in. x 1-1/2 in. nails or (24) #9 x 1-1/2 in. Simpson Strong-Tie Strong-Drive SD screws. Fasteners are not included with the connector.
- Is the GT8Z suitable for use with pressure-treated lumber?
- Yes. The ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications, making the GT8Z well-suited for use with pressure-treated lumber in outdoor gazebo construction.
