The Simpson ST9 9" Galvanized Strap Tie is a load-rated, precut strap tie from Simpson designed to resist tension loads across a wide range of structural framing applications. Built from 16-gauge steel with a Zinc Galvanized G90 finish, this economical strap tie is a go-to solution wherever top or bottom plates are cut, at wall intersections, and as ridge ties - delivering quick, reliable connections that hold up under demanding conditions.

Key Features

• Engineered to resist wind and seismic forces - provides dependable tension load resistance in structural connections subject to lateral and uplift forces, giving you confidence in code-sensitive builds
• Precut strap design - arrives ready to install with no cutting or measuring required, reducing labor time and minimizing the chance of on-site error
• 16-gauge steel construction - delivers the structural strength needed for load-rated framing connections without adding unnecessary bulk
• Zinc Galvanized G90 finish - resists corrosion in exposed or moisture-prone framing environments, helping maintain connector integrity over the life of the structure
• Compact 1-1/4 in. width - fits cleanly at wall intersections, plate breaks, and ridge tie locations where space and alignment matter

Why This Product

• A trusted Simpson strap tie built for real structural loads - this is a load-rated connector specifically engineered to resist tension, wind, and seismic forces, not just a generic metal strap, making it appropriate for applications where performance accountability matters
• Precut and ready to go - the precut format means faster installation at plate breaks, wall intersections, and ridge tie locations, cutting down on job site prep time without sacrificing performance
• G90 galvanized coating for lasting corrosion resistance - the Zinc Galvanized G90 finish helps this strap tie hold up in the kinds of framing environments where moisture exposure can compromise unprotected connectors over time
• Versatile fastener compatibility - installs with either standard nails or Strong-Drive SD Connector screws, giving contractors flexibility to work with the fastening method already on hand
