A 40ft New Cargo Container with S1 Doors is a robust, weather-resistant storage and transport unit constructed from high-strength Corten steel for long-term durability in harsh environments. Its S1 door design features a single locking bar per door, making it lighter, smoother, and easier to operate than standard double-bar ISO doors while still providing secure closure. Equipped with marine-grade plywood flooring, the container supports heavy loads and resists moisture damage. Reinforced corner castings ensure compatibility with standard lifting, stacking, and transport equipment. High-quality rubber door seals offer reliable protection against water and dust ingress, keeping cargo clean and dry. Forklift pockets enhance handling convenience in yards, warehouses, and construction sites. A built-in lockbox adds security by protecting padlocks from tampering. Ideal for storage, shipping, and container conversions, it delivers dependable performance and easy access for frequent use.
