New 40ft High Cube Shipping Container | ISO Certified & Engineering Specifications

Product Overview & Technical Specifications

Engineered to ISO 6346 and ISO 1496 standards, the 40ft High Cube Container provides an extra 12 inches of vertical clearance compared to standard dry vans. Built for continuous intermodal logistics and severe industrial deployment, every unit is constructed from high-tensile weathering steel and finished with a multi-layer marine-grade coating system.

Material Specifications & Manufacturing Process

Steel Composition & Wall Structure
Material Grade: JIS SPA-H / Corten-A structural weathering steel used for all exterior corrugated panels, roof sheets, and structural posts. Contains copper, chromium, and nickel alloy elements that inhibit atmospheric corrosion.

Panel Thickness: 2.0 mm cold-rolled corrugated steel sheets for sidewalls and front walls; 2.0 mm to 3.0 mm for roof panels.

Frame & Corner Castings: JIS SM490YA structural steel framework welded to ISO 1161 compliant forged corner castings, rated for vertical stacking of up to 9 high loaded containers (32,500 kg per stack).

Flooring & Undercarriage
Floor Material: 28 mm thick marine-grade waterproof hardwood plywood (Apitong or Keruing species), screw-fastened with countersunk self-tapping bolts to understructure cross-members.

Cross-members: Rolled steel channel sections (C-profile) welded at 305 mm intervals, providing a point-load capacity of 7,260 kg per wheel (tested with 4.4-ton forklift axle loads).

Surface Treatment & Anti-Corrosion Process
Shot Blasting: Complete abrasive blast cleaning to Sa 2.5 standard to eliminate mill scale and oxidation.

Shop Primer: Immediate application of a 20-micron zinc-rich shop primer to bare steel.

Epoxy Primer: 75-micron zinc-phosphosilicate epoxy primer coat applied via airless spray.

Intermediate Coat: 75-micron high-build epoxy intermediate layer.

Topcoat: 50-micron aliphatic polyurethane (PU) finish coat (RAL color specified per order). Total dry film thickness (DFT) exceeds 220 microns.

Undercoating: Bituminous or wax-based undercoating applied to the bottom chassis to protect against road salt and moisture pooling.

Quality Control, Testing & Compliance

Every production batch undergoes strict quality audits before issuance of the safety approval plate.

Watertightness Testing:

100% spray-bar testing using high-pressure water jets (minimum nozzle pressure 0.1 MPa) directed at all seams, welds, and door gaskets to verify zero water ingress.

Dimensional & Squareness Inspection:

Laser tolerance checks verifying structural squareness (diagonal difference within +/- 3 mm), external height, and forklift pocket alignment.

Door Operability Test:

Manual opening and closing torque checks on locking cam gear assemblies, door hinges, and PVC rubber gasket compression seals.

Standard Certifications:
CSC Plate: Valid Safety Approval Plate issued in accordance with the International Convention for Safe Containers.

Classification Society: Built under survey by ABS, BV, LR, or CCS with individual mill test reports and inspection certificates available upon request.

ISO 6346: Standardized container identification, size, and type code markings.

Application Guide & Selection Matrix

Selecting the correct container variant prevents structural failure during retrofitting or logistics bottlenecks.

Application Scenario Recommended Specification Key Technical Consideration

Standard Intermodal Freight One-Trip 40ft High Cube (Standard Doors) Verify max payload limits against highway weight regulations. High Cube adds 300 mm interior height for bulky cargo.

Modular Site Offices / Workshops 40ft HC with optional insulation or pre-cut window frames Corten steel shell accommodates structural modifications. Check side-wall profile for HVAC unit mounting.

Machinery Storage / Heavy Equipment 40ft HC with heavy-duty marine plywood floor Ensure floor point-load ratings exceed tracked machinery or heavy pallet jack loads.

Supplier Evaluation & Global Logistics

Procuring containers internationally requires transparent logistics and verified factory capacity.

Production Capacity: Automated corrugated panel rolling lines and jig-welding stations yield a throughput of 150 units per day.

Global Depot Stock & One-Trip Logistics: Units are available ex-factory or from major international port depots (including Rotterdam, Antwerp, Houston, Los Angeles, and Singapore). "One-trip" containers carry a single cargo load from the manufacturing plant to the destination port, minimizing repositioning costs while maintaining factory-new condition.

Third-Party Inspection Policy: Independent inspection agencies (such as SGS or Bureau Veritas) are permitted on-site prior to final dispatch and release of bills of lading.

FAQ

Q: What is the actual internal height difference between a Standard 40ft and a 40ft High Cube container?

A: A standard 40ft dry van provides an internal height of 2,390 mm (7' 10"), whereas a 40ft High Cube provides 2,700 mm (8' 10"). The total external height of the High Cube is 2,896 mm (9' 6"), which requires clearance consideration for low-bridge transit routes.

Q: Are these containers certified for rail and maritime transport?

A: Yes. Every unit comes with an active CSC plate valid for international maritime shipping, rail transport, and road haulage, certified by an IACS classification society.

Q: Can the flooring support heavy forklift traffic?

A: The standard 28mm Apitong hardwood floor is engineered to withstand a forklift axle load of up to 7,260 kg per set of wheels (tested on a contact area of 142 x 85 mm). For continuous heavy industrial handling, steel floor reinforcement plates can be requested.

Q: What color options are available for bulk orders?

A: Standard stock colors include RAL 5010 (Gentian Blue) and RAL 7035 (Light Grey). Custom RAL color codes and corporate logos can be applied during the wet-paint manufacturing cycle for orders meeting minimum batch quantities.
