3. Material, Coating & Structural Specifications
Steel Construction: Heavy-gauge corrugated Corten A-grade weathering steel shell, offering maximum structural strength, impact resistance, and long-term protection against atmospheric corrosion.
Exterior Finish: Factory-applied industrial marine-grade coating in standard corporate colors (such as RAL 7035 Gray or RAL 5010 Blue) with high UV stabilization.
Frame & Corner Castings: ISO 1161 heavy-duty structural steel corner castings and integrated forklift pockets for safe lifting, stacking, and multi-modal transport.
Flooring: 28mm marine-grade waterproof treated plywood, screw-fastened to heavy-duty cross-members, capable of handling frequent forklift traffic and heavy inventory point loads.
4. Advanced Security & Locking Infrastructure
External Security: Factory-welded heavy-duty steel lockbox shielding high-security padlocks from bolt-cutters, angle grinders, and physical leverage attacks.
Primary Cargo Doors: Standard double-wing cargo doors featuring 4 heavy-duty vertical locking cam bars with smooth galvanized handles.
Inner Locking / Secondary Defense System: Integrated internal deadbolt lock mechanism or secondary cross-bar locking system operating independently from the outer doors, providing an extra layer of defense against forced entry.
Hinge Protection: Anti-jemmy hinge plates and reinforced knuckle guards welded over door hinges to prevent pin removal or pry-bar attacks.
5. Weatherproofing & Ventilation
Weatherproofing: Full-perimeter EPDM rubber door gaskets ensuring 100% wind- and water-tightness (WWT) even with enhanced security modifications.
Airflow Management: Integrated weather-proof ventilation louvers equipped with internal security baffles to prevent internal humidity and condensation buildup without compromising physical security.
6. Logistics & Handling
Transport: Fully compatible with standard global intermodal transport logistics, including container ships, railcars, tilt-tray trucks, and side-loaders.
Site Deployment: Rapidly positioned on any level hardstand (concrete pad, asphalt, or compacted gravel) with minimal foundation requirements for instant high-security deployment.
