20 ft Standard Storage Container – Steel Construction

This 20 ft standard storage container – steel construction provides a secure, weatherproof storage solution for construction sites, warehouses, retail operations, and residential properties. For example, you can store tools, equipment, inventory, furniture, or pallets inside this rugged steel container. Therefore, this unit offers the perfect balance of durability, capacity, and value for most storage applications.

Why Choose a Standard Storage Container?

Larger 40ft containers cost more and require more delivery space. In contrast, this 20ft container offers a compact footprint that fits on smaller sites while still providing substantial storage capacity. Consequently, you gain maximum storage value without paying for unnecessary length. Moreover, the steel construction provides exceptional strength and security. Thus, this container represents the ideal choice for most storage needs.

Key Features of This Steel Storage Container

The Corten steel construction and lockable doors make this container stand out. For instance, the 1.6-2.0mm corrugated steel walls provide exceptional strength and security against break-ins. Similarly, the rubber door seals and welded seams prevent rain, snow, dust, and pests from entering your stored goods. Furthermore, the CSC safety plate confirms structural integrity for intermodal shipping if you ever need to relocate. Finally, the lockable double doors feature heavy-duty locking rods (top, bottom, and side) for maximum security.

Corten Steel Construction – Built to Last

Corten steel makes this container exceptionally durable for outdoor use anywhere. First, the weathering steel (grade S355J2W) forms a stable, self-protecting rust patina over time. Second, this patina prevents deeper corrosion, unlike standard steel that continues rusting. Third, the steel requires no painting or ongoing maintenance under normal conditions. Finally, a typical Corten steel container lasts 25+ years in outdoor conditions. Therefore, you can place this container anywhere without worrying about premature rust or structural failure.

Wind and Watertight Certification – Guaranteed Dry

Wind and watertight (WWT) represents a quality grade we verify before delivery. First, we inspect each container and confirm that all door seals remain flexible and intact. Second, we test the unit to ensure that rain cannot penetrate the walls, roof, or floor joints. Third, we verify that the doors close properly and lock securely. If you need guaranteed dry storage for sensitive items, this WWT grade delivers exactly that – your contents stay completely dry even in heavy rain or snow.

CSC Plated – Ready for Transport Anywhere

The CSC plate confirms that this container meets international safety standards for shipping. For example, the plate certifies that the container has passed structural tests for stacking, lifting, and floor strength. Likewise, the CSC certification allows legal transport on ships, trains, and trucks across international borders. If you need to relocate the container overseas for a project, this certification makes international shipping possible and customs clearance straightforward. Thus, you gain complete flexibility for both static storage and transport.

20ft Dimensions – Compact but Capacious

The 20ft length provides generous storage while fitting on most sites. For example, the internal length of approximately 19ft 4in accommodates 11 Euro pallets. Likewise, the internal width of approximately 7ft 8in-7ft 9in allows comfortable access. Furthermore, the 28mm marine ply floor supports loads up to 26,000 kg evenly distributed. If you need compact storage that doesn’t dominate your site, this 20ft container delivers the perfect balance.

The 28mm Marine Ply Floor – Built for Heavy Loads

The marine ply floor handles demanding storage applications with ease. For example, the 28mm thickness provides exceptional strength for heavy pallets, machinery, or vehicles. Likewise, the WBP (Weather and Boil Proof) adhesive resists moisture penetration, even in damp site conditions. Furthermore, the tongue-and-groove construction creates seamless coverage across the entire floor. As a result, you can store loads up to 26,000 kg evenly distributed without worrying about floor failure.

What’s Included

First, every unit includes the 20ft Corten steel container with wind and watertight certification. Second, the CSC safety plate comes affixed and valid. Third, the 28mm marine ply floor is pre-fitted. Fourth, lockable double doors with heavy-duty locking rods (top, bottom, side) and padlock hasps complete the package. Finally, forklift pockets (4) allow easy repositioning.
