The Simpson Strong-Tie CS18 18-Gauge Galvanized Coiled Strap is a continuous utility strap for wood construction. This is a coiled strap designed for wood-to-wood fastening, uplift resistance, and tension load transfer. Model Number: CS18. If you need a strap that can be cut on site to match the exact span or tie-down detail in front of you, this one gives you that flexibility in a full 200 ft. roll.

For framers, builders, and engineers working on roof uplift and shear wall overturning resistance, the big advantage here is simple: you are not locked into pre-cut lengths. The CS18 can be cut to the required length on the jobsite, which makes it useful for single 2x stud or post applications and other details where field conditions rarely match a one-size-fits-all connector. That also makes it a cost-conscious option when you want continuous strap stock on hand instead of multiple individual parts.

The core specs matter because they tell you where this strap fits. CS18 uses 18-gauge steel, measures 1-1/4 in. wide, and comes in a 200 ft. length with a G90 galvanized finish. That width is sized to fit nominal 2x lumber, which keeps layout straightforward in common framing work. The published series data also lists an allowable tension load of 1,370 lb for CS18 when installed with the specified fastener schedule, so this is a real structural connector product, not general-purpose punched metal strapping.

On the job, the punched hole pattern helps speed fastening and makes layout more predictable when you are tying members together across a wall, floor line, or uplift path. Simpson Strong-Tie also notes that the strap is used for roof uplift and shear wall overturning resistance, which is where this style of connector earns its keep. When the detail calls for a long, continuous tie that can bridge framing members and keep the load path intact, a coiled strap like this is usually the practical move.

From a jobsite handling standpoint, the CS18 is packaged as a single roll in a lightweight carton. That matters more than it sounds like it should. It is easier to keep clean, store on the truck, and pull out when you need custom lengths during framing or repair work. Because it is coiled stock, you can keep one roll available for multiple connection details instead of chasing down the exact pre-cut part number every time.

Installation details matter with straps, and Simpson Strong-Tie is pretty clear about it. Use all specified fasteners to achieve published load values, follow applicable code requirements for nail penetration and wood edge and end distances, and account for wood shrinkage across horizontal members since that can cause the strap to buckle outward. For lap splices and alternative nailing schedules, the engineer or designer of record needs to verify the detail against the design load.

Who should buy it? This is a good fit for framers, general contractors, remodelers, and structural repair crews who need a cut-to-length fastening solution for wood framing. It is especially useful when you are dealing with uplift load paths, tiedown details, wall reinforcement, or field-built connections where fixed-length straps are more hassle than help. If your work includes code-driven structural fastening and you want a continuous roll ready to trim as needed, the Simpson Strong-Tie CS18 18-Gauge Galvanized Coiled Strap makes a lot of sense.

Simpson Strong-Tie CS18 18-Gauge Galvanized Coiled Strap keeps field-built details simple

If you do framing or structural repair work and want one roll you can cut for a bunch of different tie details, this is the smart way to stock strap material.

• Who it's for: Framers, contractors, and repair crews handling wood-to-wood structural connections, uplift details, and wall reinforcement.
• Why it stands out: The 200 ft. length, nominal 2x fit, and jobsite cut-to-length flexibility make it more useful than fixed strap lengths when real framing conditions are not perfectly repeatable.
• Worth knowing: This is a structural connector product, so fastener schedule and end length matter. Buy it for code-driven fastening details, not as generic metal strapping.

• What is the Simpson Strong-Tie CS18 18-Gauge Galvanized Coiled Strap used for? It is used for wood-to-wood fastening, including roof uplift resistance and shear wall overturning resistance applications.
• Can this coiled strap be cut on site? Yes. The CS series is designed to be cut to length on the jobsite for custom connection details.
• What size lumber does it fit? The strap is sized to fit nominal 2x lumber.
• What finish does the CS18 use? The CS18 uses a zinc galvanized G90 finish.
