Buy 40hc Open Top Shipping Container Factory & Products

A standard 40ft Open Top container has an external height of 8 feet 6 inches (2,591 mm), whereas a 40ft High Cube Open Top (40HC OT) stands at 9 feet 6 inches (2,896 mm). This gives the High Cube variant an extra 1 foot (~305 mm) of vertical clearance, increasing internal cubic capacity from roughly 65.5 m³ to nearly 75.8 m³. For out-of-gauge (OOG) machinery, heavy engines, and vertical crated gear, this height makes the difference between fitting inside a weather-protected open-top container or being forced onto an exposed flat-rack or cost-prohibitive breakbulk vessel.

The rear top header is designed with heavy-duty mechanical hinge pins that allow it to be unlocked and swung completely outward or removed entirely during cargo staging. This eliminates the fixed upper door rail restriction, enabling overhead cranes to drop cargo directly through the roof, or allowing tall forklift masts to drive cargo directly past the door line without risk of collision. Once loaded, the swing header is re-engaged, locked, and sealed to maintain the structural squareness and diagonal stiffness of the container frame.

All our 40HC Open Top shipping containers are fabricated exclusively from authentic high-strength SPA-H Corten steel (atmospheric corrosion-resistant weathering steel). During the multi-stage finishing process, the steel plates undergo full grit-blasting to Swedish SA 2.5 standard, followed by an immediate application of a high-performance zinc-rich epoxy primer, an epoxy intermediate build coat, and a durable UV-stabilized polyurethane topcoat. This produces a dry film thickness (DFT) exceeding 120 microns, designed to resist ocean sea spray, harsh coastal UV radiation, and severe acid-alkali industrial environments.

Yes. Provided the cargo does not protrude beyond the roofline (In-Gauge), 40HC Open Top containers conform fully to ISO corner casting dimensions and structural strength standards (ISO 1496-1). They are tested to withstand stacking loads of up to 216,000 kg (9-high stacking in cellular ship holds). If cargo protrudes vertically (Over-Height / Out-of-Gauge), the container must be booked as Out-of-Gauge (OOG) cargo, occupying the top tier on the vessel deck or a designated open slot.

Each manufactured unit is supplied with an official CSC (Convention for Safe Containers) safety approval plate and a Customs Container Convention (CCC) stamp. Structural tests are monitored and certified by leading global classification societies, including Bureau Veritas (BV), ABS, or CCS. This documentation guarantees hassle-free acceptance across all major ocean freight carriers, intermodal rail lines (UIC), and international customs checkpoints worldwide.

We offer extensive OEM/ODM engineering capabilities for special requirements. Custom options include reinforced diamond-checkered steel floors instead of timber, internal ladder rungs, heavy-capacity forklift pockets, customized lashing configurations up to 4,000 daN, personalized corporate livery paint codes, hard top removable steel roof conversions, and tailored tarpaulin weights (up to 900g/m²). Our engineering teams review technical drawings before production to ensure proper weight distribution and structural integrity.
