Hammerhead: Benefits of Garrison's USA Made Flood Wall
Made entirely in the United States, Hammerhead is more than just a flood barrier—it’s a highly engineered,
industrial-grade solution designed to perform when everything else fails.
As flood risks continue to rise across the country—particularly in coastal and hurricane-prone regions—property owners are turning to permanent flood protection systems that offer real results. When the goal is to protect your infrastructure, business, or municipal buildings from catastrophic water intrusion, there's no room for compromise. That’s where the Hammerhead Flood Wall System from Garrison Flood Control stands above the rest.
Made entirely in the United States, Hammerhead is more than just a flood barrier—it’s a highly engineered, industrial-grade solution designed to perform when everything else fails. Here's why Hammerhead is setting the new standard in flood wall protection.
Unmatched Effectiveness in Flood Defense
Floods aren’t just inconvenient—they’re destructive, expensive, and in many cases, unavoidable. The Hammerhead Flood Wall System offers a permanent base channel installation, allowing flood planks to be rapidly deployed and secured before a flood event. This system is designed for speed, efficiency, and long-term durability, giving you peace of mind knowing you’re protected with a defense system engineered for real-world scenarios.
The Hammerhead uses high-strength aluminum flood planks stacked and secured between vertical posts. The channels are permanently installed in concrete at the location, enabling fast activation whenever needed. What sets it apart from other systems is its modular nature—easy to install, remove, and store without heavy machinery or complex assembly.
From government agencies to commercial property owners, Hammerhead provides a custom-engineered flood wall solution that meets the needs of high-risk locations without compromising on aesthetics or ease of use.
Why USA-Made Flood Walls Matter More Than Ever
Let’s be honest—flood barriers aren’t something you want to gamble on with inferior materials or questionable suppliers. Over the past few years, we’ve seen some knockoff flood wall systems come and go from the market, most of whom use cheap materials, inconsistent manufacturing standards, no testing and subpar engineering tolerances. The result? Increased risk during the most critical moments.
At Garrison Flood Control, we believe that protecting your property deserves more than cut corners and imported shortcuts. That’s why Hammerhead is fully designed, manufactured, and assembled in Florida, serving as a true OEM manufacturer of American-made flood barrier systems.
Domestic manufacturing gives us full control over every step of the process—from precision cutting to material testing and system validation. This commitment ensures that every product leaving our facility meets strict standards for quality and performance. And we are here to support you after the purchase.
T6 Aluminum: Built Stronger for Longer
One of the biggest differences between Hammerhead and many overseas alternatives lies in the materials used. While many international products rely on T5 aluminum, which offers limited strength and durability, Garrison uses 6063 T6 aluminum in the fabrication of our flood planks and structural components.
Why does that matter?
T6 aluminum is significantly stronger than T5, offering greater resistance to deformation and impact during high-pressure water events.
It delivers better corrosion resistance, ensuring your flood wall lasts longer, especially in coastal or wet environments.
It enhances the structural integrity of the system, providing reliable performance for years—without compromising on weight or handling.
This choice isn’t just about specs—it’s about ensuring your property is protected by a flood barrier that performs under pressure.
Superior Castings & Hardware
When it comes to flood protection, the integrity of the materials used can make or break system performance. That’s why Garrison’s Hammerhead Flood Wall is engineered with superior castings and high-grade hardware that set it apart from international alternatives.
Castings: Garrison relies on true die castings—formed under extreme pressure—for unmatched strength, precision, and durability. These die cast components are inherently denser and more resistant to both mechanical stress and environmental corrosion. In contrast, many offshore knockoff products use sand casting methods, which can leave porous areas and internal weak spots prone to rusting, cracking, and premature failure.
Hardware: Garrison also specifies marine-grade A4 316L stainless steel for all structural hardware. This level of stainless steel offers the highest resistance to corrosion, especially in harsh coastal or flood-prone environments. Meanwhile, imported imitations often cut corners by using 304 stainless steel—or even falsely label it as marine grade—despite its lower durability and limited ability to withstand long-term exposure to saltwater or moisture.
With Garrison, you're not just getting a flood wall—you’re investing in material quality that’s built to endure.
Computer Controlled Precision. Every Time.
Another key advantage of the Hammerhead system is our use of automated aluminum cutting machines for exacting precision in every part we produce. Precision matters in flood protection—any deviation can lead to leaks or weak points that undermine the entire system.
With computer guided accuracy, our components are manufactured to tight tolerances, which means each plank fits securely in place and performs exactly as designed. This level of engineering precision simply isn’t possible with many overseas manufacturing processes where quality control can vary widely.
Quality Control You Can Count On
Garrison Flood Control operates with a rigorous system of domestic quality control, ensuring every flood wall we produce meets our exacting standards. By manufacturing right here in the United States, we’re able to monitor and test materials, components, and final assemblies with a level of detail that would be nearly impossible to replicate offshore.
This oversight allows us to quickly adapt to customer needs, respond to feedback, and maintain full accountability throughout the manufacturing process. Our reputation is built on trust, and we take that responsibility seriously—especially when the stakes are high.
Expanding to Serve More Communities
As demand grows for reliable and permanent flood protection systems, Garrison Flood Control is scaling up to meet the challenge. We’ve expanded our production square footage in Florida, giving us even greater capabilities to serve communities, businesses, and municipalities across the country.
This expansion is more than just square feet—it’s an investment in American infrastructure, job creation, and flood resilience. We’re proud to offer efficient lead times, enhanced customer service, and a faster response to emergency projects—because protecting what matters most shouldn’t have to wait.
