20ft High Cube Storage Container | Technical Specification & Procurement Guide
Product Overview & Key Specifications
The 20ft High Cube Storage Container provides an external height of 9 feet 6 inches (2,896 mm)-delivering an extra 300 mm (12 inches) of vertical clearance over standard 20ft dry containers. Built to ISO standards for intermodal transport and heavy-duty industrial storage, this unit accommodates taller machinery, multi-tier pallet racking, and bulky inventory while maintaining a compact 20-foot spatial footprint.

Material & Structural Standards
Structural longevity depends directly on steel grade selection, weld integrity, and corrosion protection layers.
Corrosion-Resistant Steel: The entire structural frame and corrugated panels utilize JIS SPA-H Corten weathering steel, offering atmospheric corrosion resistance up to 8 times higher than conventional carbon structural steel.
Wall & Roof Panels: 1.6 mm thick cold-rolled Cor-Ten corrugated sheets. Vertical corrugation depth is engineered at 50 mm to optimize lateral wind load resistance.
Floor Construction: 28 mm thick marine-grade apitong or bamboo-composite plywood, treated with industrial fungicidal and insect-repellent preservatives, secured to transverse steel crossmembers via countersunk self-tapping screws.
Corner Castings: Drop-forged SCW463 steel corner castings conforming strictly to ISO 1161 specifications, rated for top-lift stacking up to 9 high loaded containers.
Manufacturing Process & Quality Control
Every container is fabricated on automated assembly jigs to maintain dimensional accuracy, squareness, and structural integrity.
Surface Preparation: All raw steel components undergo automated abrasive shot blasting to ISO 8501-1 Sa 2.5 standard to completely eliminate mill scale, rust, and surface contaminants prior to coating.
Coating System:
Primer: Zinc-rich epoxy primer (Dry film thickness: 40 μm).
Intermediate Coat: High-build epoxy coat (Dry film thickness: 80 μm).
Topcoat: Chlorinated rubber or polyurethane exterior finish coat (Dry film thickness: 40 μm). Total dry film thickness exceeds 160 μm.
Watertightness Verification: Each completed unit undergoes a high-pressure rotary water jet test (nozzles delivering water at 1.5 bar pressure from a distance of 1.5 meters) along all door gaskets and weld seams to guarantee zero water ingress.
Application Suitability & Selection Matrix
Selecting the correct container specification prevents operational bottlenecks during field deployment.

Compliance, Testing & Certifications
Compliance documentation is supplied directly with each batch to streamline customs clearance and satisfy workplace safety standards:
CSC Certification: Certified under the International Convention for Safe Containers (CSC). Each unit bears a valid CSC safety approval plate issued by recognized classification societies (ABS, BV, LR, or CCS).
ISO Compliance: Manufactured in strict accordance with ISO 668 (Classification, dimensions, and ratings), ISO 1496-1 (Series 1 freight containers – Specification and testing), and ISO 6346 (Coding, identification, and marking).
TIR Compliance: Complies with Customs Convention on the International Transport of Goods under Cover of TIR Carnets where applicable.
Supplier Evaluation Checklist: What to Audit
When vetting an industrial container manufacturer, verify these critical technical checkpoints:
Plate Traceability: Request mill test certificates (MTC) confirming the actual use of genuine SPA-H Corten steel rather than substitute structural carbon steel (such as Q235).
Weld Qualification: Ensure welding operators hold current certifications to AWS D1.1 or ISO 9606-1 standards, supported by routine ultrasonic or magnetic particle weld inspections.
Lifting Load Test Reports: Verify that factory test benches perform prototype lifting and floor concentration tests per ISO 1496-1 protocols.
Customization Capabilities: Confirm engineering capacity for non-standard modifications (e.g., personnel doors, roll-up shutter doors, electrical distribution packages, or custom corporate color matching via RAL color charts).
