The Simpson Strong-Tie CS18S is a continuous utility coiled strap designed to join and reinforce structural connections across a wide range of light repair and heavy-duty construction applications. This 100-foot roll of 18-gauge galvanized steel can be cut to the exact length needed directly on the job site, eliminating waste and reducing the need for pre-cut strap inventory. Sized to fit nominal 2x lumber, it works on the wide or narrow face of a member and installs with common 8d or 10d nails for fast, straightforward placement. A G90 zinc-galvanized coating provides extra corrosion resistance, making the CS18S a reliable choice for uplift resistance, horizontal tension, and a variety of other structural connections.

Key Features

• Sized to fit nominal 2x lumber - matches standard stud and post dimensions so no adjustment or shimming is needed on typical framing applications.
• 100-foot continuous coil - cut straps to any length on the job site, reducing leftover material and making one roll useful across multiple connections in a single project.
• 18-gauge steel construction - delivers the strength and rigidity required for approved structural applications including roof uplift and shear wall overturning resistance.
• G90 zinc-galvanized coating - provides extra corrosion resistance compared to standard galvanized finishes, supporting long-term performance in demanding environments.
• Packaged in a lightweight carton - easy to transport and handle on site without requiring special equipment or storage accommodations.

Why This Product

• Job-site flexibility built in - because the CS18S ships as a continuous 100-foot coil, one roll can serve as a single-stud tie, a horizontal tension strap, or a floor-to-floor uplift connector, adapting to whatever the project demands without pre-ordering specific lengths.
• Approved for critical structural connections - the CS18S is engineered for verified applications including roof uplift resistance and shear wall overturning resistance, giving builders confidence that the strap meets the performance requirements of the connection.
• Extra corrosion protection without a finish upgrade - the G90 zinc-galvanized coating is built into the standard product, so buyers get enhanced durability at no additional specification step or cost premium over a basic galvanized alternative.
• Simpson Strong-Tie engineering behind every roll - backed by the same brand known for versatile, code-recognized connector solutions, the CS18S is made in the United States and sized to work alongside common framing fasteners already on the job site.
