High Cube Standard Storage Container

High Cube Standard Storage Container | Structural & Procurement Specifications

The High Cube Standard Storage Container provides an external height of 9'6" (2,896 mm), offering an additional 304 mm (1 foot) of vertical clearance over standard dry storage containers. Engineered for high-volume logistics and rugged on-site industrial storage, this unit accommodates taller cargo, bulk pallet racking, and specialized machinery. Constructed from Corten-A (SPA-H) structural weathering steel and compliant with ISO 668, ISO 1496-1, and CSC safety regulations, it is built to withstand rigorous multimodal transit and harsh weather conditions.

Use the matrix below to verify dimensional compatibility, payload limits, and structural compliance for your operational requirements.

Selecting the correct configuration depends on payload density, site footprint constraints, and access frequency:

20-Foot High Cube Container (20'HC):
Application Focus: High-density heavy machinery, dense palletized inventory, or restricted spatial footprints where 40-foot units cannot maneuver.

Operational Advantage: Higher payload density per linear foot; easier local truck chassis transport without route permits in restricted municipalities.

40-Foot High Cube Container (40'HC):
Application Focus: Bulk inventory storage, voluminous lightweight goods, long industrial equipment, and modular office conversion projects.

Operational Advantage: Lower cost per cubic meter for bulk shipments; wider interior layout options for custom shelving and workshop installations.

Engineered for heavy-duty commercial environments, these units serve distinct operational functions:

Industrial On-Site Storage: Secure weather-tight housing for spare parts, maintenance tools, and raw materials at manufacturing plants, mining sites, and energy installations.

Modular Conversion Projects: Utilized by engineering contractors as mobile site offices, electrical control rooms, and equipment enclosures due to the extra vertical headroom required for cable trays and HVAC ducting.

Intermodal Logistics: Fully certified for maritime container ships, rail networks (AAR approval), and over-the-road chassis transport.

Evaluating structural reliability requires examining raw materials, welding standards, and quality control protocols:

Material Composition: Wall panels, roof sheets, and door frames are roll-formed from Corten-A (SPA-H) structural weathering steel, containing copper, chromium, and nickel additives to inhibit atmospheric corrosion. Minimum sheet thickness: 1.6 mm to 2.0 mm.

Structural Frame: Corner posts and bottom side rails utilize cold-rolled open sections with a thickness of 4.5 mm to 6.0 mm, ensuring maximum rigidity during tandem crane lifting and multi-tier stacking.

Welding Standards: All structural seams are executed via Semi-Automatic CO2 Gas Shielded Arc Welding by operators certified to AWS D1.1 / EN ISO 9606 standards. Full penetration welds are applied on corner castings and main crossmembers.

Flooring Specifications: Fitted with 28 mm thick Apitong/Keruing marine-grade hardwood plywood or high-density bamboo composite, secured with anti-shear M8 countersunk bolts to withstand a 7,260 kg (16,000 lbs) forklift axle load per ISO 1496 testing standards.

Surface Treatment & Coating System:
Abrasive Blast Cleaning: Sa 2.5 standard blast cleaning to remove mill scale and impurities.

Primer: 20-25 um zinc-rich epoxy primer.

Intermediate Coat: 40-60 um high-build epoxy coat.

Topcoat: 30-40 um acrylic polyurethane finish (total dry film thickness >= 100 um). Salt spray resistance tested to 3,000+ hours per ASTM B117.

Every production batch undergoes rigorous factory acceptance testing (FAT) before issuance of certification:

Watertightness Testing: Every completed unit undergoes a high-pressure water jet test (>= 100 kPa nozzle pressure at a distance of 1.5 meters) to guarantee zero water ingress.

Dimensional & Squareness Verification: Measured using laser alignment tools to ensure diagonal tolerances do not exceed +/- 3.0 mm.

Regulatory Certifications:
CSC (Convention for Safe Containers): Safety approval plate affixed to every unit, validating structural safety for international shipping. (Reference visual: Stamped metal CSC plate positioned on the right exterior door leaf).

Classification Society Approval: Third-party inspection certificates available upon request from major societies (ABS, BV, LR, DNV).

TIR / ISO / UIC Compliance: Fully certified for international customs transit by rail and road.

Minimum Order Quantity (MOQ): Standard 1-unit minimum for yard pickup; optimized freight economics apply for One-Way leasing or 20'/40' FCL bulk ocean shipments.

Packaging & Delivery Logistics: Shipped as "SOC" (Shipper-Owned Containers) loaded in stack configurations (typically 1x20' + 2x40' modular pairings) or repositioned via dry cargo vessels.

Customization Options: Custom RAL color branding, alternative door placements (roll-up doors, side-opening doors), high-security lock boxes, and lashing point configurations available for volume orders.

To obtain an accurate quotation including destination port delivery or factory EXW pricing, please provide the following parameters in your inquiry:

Model & Quantity: (e.g., 20 units of 40' High Cube Containers)

Destination Port / Delivery Location: (City, State/Province, Zip Code)

Compliance Requirements: (Standard CSC plate only vs. specific Classification Society certification like ABS/LR)

Customization Needs: (Standard factory paint / RAL code / security lock box)
