Engineered for
Long Life.
Corrosion-resistant port and marine storage designed to withstand salt air, humidity, and coastal weather—eliminating the maintenance cycles that destroy traditional steel structures.
Decades of Coastal Performance.
Salt air accelerates corrosion. Traditional steel buildings near waterways deteriorate rapidly from constant exposure to humidity, salt spray, and marine environments—forcing port operators into repeated replacement cycles that drain capital budgets and disrupt operations.
Legacy's marine-grade corrosion resistance eliminates this cycle. Our proprietary EpoxxiShield™ coating systems provide superior protection against salt air and humidity, while our non-corrosive ExxoTec™ PVC cladding remains inert to marine conditions—delivering decades of reliable performance without the maintenance burden and recurring replacement costs of traditional steel construction.
What Type of Marine Storage
Do You Need?
Roof-Only Pavilions
Best for: Vessel storage, covered cargo staging, equipment protection, operations requiring ventilation and easy multi-side access
Weather protection with natural ventilation and daylighting. Non-corrosive ExxoTec™ PVC cladding eliminates metal roofing vulnerabilities in salt air. EpoxxiShield™-coated solid I-beams resist marine corrosion better than tube trusses while supporting heavy cranes and conveyors without interior columns obstructing vessel movement.
Enclosed & Uninsulated
Best for: Year-round cargo protection, enclosed vessel maintenance, dust/debris containment, operations requiring full environmental control
Complete weather protection with passive climate moderation. Non-corrosive ExxoTec™ PVC cladding and EpoxxiShield™-coated I-beams outperform metal construction in marine environments. White cladding provides 12% translucency, which can allow for natural daylighting. Passive ventilation manages humidity without mechanical systems. Clear span design supports heavy equipment without interior columns restricting operations.

Solve Your Biggest
Marine Storage Challenges
Port and waterways operations face unique constraints—accelerated corrosion that destroys infrastructure investments, limited vessel capacity that restricts revenue, operational inefficiencies that impact profitability, and construction timelines that can't accommodate seasonal weather windows.
-
Corrosion in Marine Environments
Traditional steel buildings near waterways deteriorate predictably and rapidly. Salt air accelerates corrosion exponentially—what takes decades inland happens in years at the coast. Maintenance cycles compound—each repair exposes fresh steel to salt air, accelerating subsequent deterioration.
Legacy's corrosion-resistant technology delivers lower total cost of ownership. Our proprietary epoxy coatings provide corrosion resistance far superior to hot-dip galvanizing in salt air environments. ExxoTec™ PVC cladding is naturally inert to salt spray, humidity, and marine conditions—it cannot rust, pit, or corrode regardless of coastal exposure intensity.
-
Vessel Storage Capacity Limitations
Traditional storage layouts force inefficient vessel positioning, create dead zones where vessels can't be safely maneuvered, prevent optimal trailer access, and limit the range of vessel sizes you can accept.
Legacy's engineered Clear Span design up to 300 feet wide eliminates interior obstructions, maximizing revenue-generating storage capacity. Your storage layout can also evolve as vessel mix changes—no structural columns forcing permanent configuration constraints.
-
Construction Timeline Constraints
Extended construction timelines compound costs and restrict operational windows. Coastal construction is limited by hurricane seasons, winter storms, and weather-dependent installation requirements, and longer projects expose you to material price increases, labor rate escalation, and unpredictable cost overruns.
Legacy's vertically integrated process—design, engineering, manufacturing, and installation all in-house—delivers operational facilities faster. Our in-house engineering team works directly with manufacturing, resolving potential issues before they become costly delays. Every component built in our 87,000 sq ft Minnesota facility under rigorous quality control—no supply chain delays, no coordination between multiple suppliers.
-
Operational Efficiency
Inadequate facility design creates ongoing operational friction that compounds costs. Traditional metal buildings require constant artificial lighting—expensive in marine environments where facilities operate extended hours or 24/7. Metal buildings also become ovens in coastal sun exposure—dangerous working conditions, accelerated equipment corrosion from condensation, higher HVAC costs.
Our white ExxoTec™ cladding can provide natural daylight throughout the facility during operating hours—reducing electricity costs while creating safer, more productive working conditions. Our ventilation system with strategically placed soffits and gravity vents manages salt air and humidity without mechanical systems. Clear Span design accommodates any configuration—gantry cranes for vessel handling, bridge cranes for cargo operations, high-bay storage, specialized marine equipment—without interior columns restricting operations.
