The Simpson PSQ418 4x18 Piling Strap Quick-Install, Hot-Dip Galvanized is a load-rated, precut strap engineered by Simpson to create a strong, reliable connection between wood girders and piles, supporting heavy, concentrated loads in demanding structural applications. Designed for quick installation and optimal performance, this pile strap is built to resist wind and seismic forces, making it a dependable choice for pier, dock, and foundation framing where connection integrity is critical.

Key Features

• Hot-dip galvanized (HDG) coating - provides corrosion resistance so the strap holds up in harsh, moisture-prone environments without compromising structural performance over time.
• Load-rated, precut design - eliminates field cutting and guesswork, allowing for faster, more consistent installations while ensuring the connection meets rated load requirements.
• Engineered for wind and seismic resistance - gives builders and engineers confidence that the girder-to-pile connection can handle lateral and uplift forces common in coastal and high-wind regions.
• Greatest strength achieved when wood members are notched - encourages proper installation technique that maximizes load transfer between the pile and girder for a more secure structural connection.
• Compatible with Strong-Drive SDWH Timber-Hex HDG screws - pairs with fasteners specifically matched to the strap's coating and load requirements, ensuring a consistent, code-compliant installation.

Why This Product

• Purpose-built for pile-to-girder connections - rather than a generic strapping solution, this strap is specifically engineered to handle the heavy, concentrated loads that occur where wood girders bear on piles, reducing risk of connection failure in critical framing scenarios.
• Quick-install design saves time on the job - the precut, ready-to-use format means less time spent measuring and cutting on site, which is especially valuable in repetitive pile framing applications such as decks, docks, and elevated structures.
• Hot-dip galvanized for long-term durability - the HDG coating is well suited for outdoor and waterfront environments where exposure to moisture and salt air can degrade lesser-protected hardware, helping protect the structural connection for the life of the build.
• Trusted Simpson engineering - backed by Simpson's reputation for load-tested, code-referenced structural connectors, this strap gives contractors and inspectors a recognized product with documented performance data for wind and seismic applications.
