Material & Structural Construction

Corrosion-Resistant Steel: Corner posts, side walls, and roof panels utilize Corten-A (SPA-H) weathering steel. This alloy forms a stable rust-inhibiting surface patina when exposed to marine atmospheres, reducing long-term maintenance costs.

Structural Framing: Rolled and pressed structural steel sections (thicknesses ranging from 4.0mm to 6.0mm) ensure torsional rigidity under maximum stacking loads (rated for up to 9 high stacks of 24,000 kg units).

Flooring System: 28mm thick marine-grade laminated hardwood (Apitong/Keruing) treated with water-resistant preservatives, secured to crossmembers using countersunk self-tapping screws. Designed to withstand a forklift axle load of 7,260 kg per 29-square-centimeter contact area.

Corner Castings: Drop-forged steel corner castings conforming to ISO 1161, fully weld-tested for spreader lock engagement and securing twistlocks.

Manufacturing & Quality Control Process

Shot Blasting & Surface Prep:

Raw steel plates and profiles undergo automatic abrasive blast cleaning to Sa 2.5 standard to eliminate mill scale and impurities prior to fabrication.

Automated Welding:

Main structural seams utilize semi-automatic CO2 gas-shielded arc welding by certified operators following AWS D1.1 standards.

Coating Application:
Shop-primer applied immediately post-blast to prevent flash rusting.

Multi-layer marine coating system: Zinc-rich epoxy primer (~40 um), high-build epoxy intermediate coat (~80 um), and polyurethane (PU) topcoat (~40 um total dry film thickness). Total coating thickness exceeds 160 um.

Watertightness Testing: Every completed unit undergoes a high-pressure water jet test (nozzle pressure >= 1 bar, distance <= 1.5 m) to verify absolute seal integrity around door gaskets and roof seams.

Compliance & Certifications

CSC (Convention for Safe Containers): Valid safety approval plate affixed to the exterior door, certifying structural strength for international multi-modal transport.

Classification Society Inspection: Each production batch is inspected and certified by major classification societies (ABS, BV, LR, or CCS), providing individual test reports covering dimensions, weight, load testing, and watertightness.

TIR Compliance: Built in accordance with Customs Convention on the International Transport of Goods Under Cover of TIR carnets, featuring secure cable-lacing brackets and rivet-sealed customs plates.

Application Selection Guide

Application	Suitability Analysis	Key Operational Consideration
Palletized Cargo Transport	Accommodates standard Euro-pallets (1200 x 800 mm) in double-stacked configurations due to the 2,352 mm internal width.	Verify total payload distribution against local highway axle-weight limits.
Oversized / Volumetric Goods	The extra 300 mm vertical clearance accommodates tall machinery, garment racks, and light industrial equipment.	Check crane clearance and terminal gantry limits for 9'6" height restrictions.
Stationary Industrial Storage	High clearance allows vertical shelving installation and forklift maneuverability indoors.	Ensure proper site leveling and foundation blocking under corner castings.

FAQ

Q: What is the exact difference in payload capacity between a standard 40ft Dry Container (DV) and a 40ft High Cube (HC)?

A: While both share a maximum gross weight rating of 32,500 kg under modern ISO conventions, the 40'HC has a higher tare weight (~3,900 kg vs. 3,700 kg for standard DV) due to taller side panels. Consequently, the net payload capacity of the 40'HC is approximately 200 kg lower than a standard dry van, traded off for an extra 9 m3 of volume capacity.

Q: Can these containers be handled by standard spreaders and container cranes?

A: Yes. External corner castings conform strictly to ISO 1161 dimensions. Top, bottom, and side apertures match standard top-lift spreaders, reach stackers, and trailer twistlocks without modification.

Q: What documentation is provided upon factory dispatch?

A: Every delivery includes:
Class Certificate (ABS/BV/LR/CCS)
CSC Safety Approval Certificate
Manufacturer's Inspection Report (Dimensions, Tare Weight, and Watertight Test verification)
Bill of Materials and Paint Specification Sheet

Q: What is the standard surface treatment warranty against rust perforation?

A: The standard marine-grade epoxy/polyurethane coating system carries a 5-year structural integrity guarantee against major paint breakdown under normal atmospheric conditions (ISO 12944 C3 environment).
