The Simpson Heavy Strap Tie is a heavy, load-rated, precut strap engineered by Simpson to support heavy, concentrated loads by creating a strong connection between wood girders and piles. Fabricated from 7-gauge steel and finished with hot-dip galvanization, this robust strap tie is built to resist wind and seismic forces, making it a dependable choice for demanding structural connections in exterior and treated-wood applications. Versatile enough for use on the wide or narrow face of lumber, it delivers the combination of strength and corrosion resistance that heavy-duty timber framing and pile connections require.

Key Features

• 7-gauge steel construction - provides the substantial thickness and load capacity needed to handle heavy, concentrated structural loads without compromise
• Hot-dip galvanized coating - delivers extra corrosion resistance compared to standard finishes, making this strap tie well suited for exterior environments and applications involving treated lumber
• Installs with machine bolts - bolt-style installation creates a secure, rigid connection between wood girders and piles for reliable long-term structural performance
• Precut to 2-1/2 in. x 21-1/4 in. - the ready-to-install, load-rated format eliminates field cutting and guesswork, saving installation time on heavy-duty projects
• Designed to resist wind and seismic forces - engineered to meet the demands of structural connections where lateral and uplift loads are a critical design consideration

Why This Product

• Purpose-built for heavy structural connections - unlike light-duty straps, this heavy strap tie is specifically designed to connect wood girders to piles under heavy, concentrated loads, giving builders a load-rated solution they can count on in critical structural assemblies
• HDG coating matched throughout the connection - because the strap installs with hot-dip galvanized bolts and carries its own HDG finish, every component of the connection shares the same corrosion-resistant standard, reducing the risk of galvanic incompatibility in treated-wood and exterior settings
• Wind and seismic resistance built in - the HST2HDG is engineered from the ground up to resist lateral and seismic forces, providing structural confidence in regions where wind uplift and earthquake loading are part of the design equation
• Simple, versatile installation - as part of Simpson's broad family of straps and plates, this heavy strap tie works on the wide or narrow face of lumber and installs straightforwardly with machine bolts, making it practical for a wide range of heavy-duty timber framing and pile connection scenarios
