OEM Open Top Container 20ft Factory & Exporters

A Soft Top 20ft Open Top container utilizes removable curved steel roof bows that support a heavy-duty, reinforced PVC tarpaulin secured with an eyelet rim and customs-approved TIR sealing cable. It offers maximum vertical flexibility, lightweight roof assembly, and rapid dismantling for cargo extending slightly above the top rail profile.

Conversely, a Hard Top container incorporates a rigid, removable Corten steel roof cover that can be hoisted using slings or dedicated forklift pockets. The hard top provides heightened anti-theft security, superior environmental resistance, and can be stacked in the same manner as a standard dry GP container when the lid is locked, without requiring upper cargo bay tier restrictions on container vessels.

Yes. When cargo dimensions remain entirely within the box internal boundary (height < 2,348 mm), the container is transported as an In-Gauge (IG) load with the roof bows and tarp secured in place. When the machine or structure projects above the top rail line, it is designated as Out-of-Gauge (OOG) freight.

For OOG consignments, specialized over-height tarpaulins or protective packing sheets are fitted, and the vessel slots are booked specifically on the top deck tier or within customized cellular bays where overhead clearance is allocated by maritime vessel planners.

The customs security of an open top unit is governed by the Customs Convention on the International Transport of Goods Under Cover of TIR Carnets. The PVC tarpaulin is engineered with reinforced hems containing stainless steel grommets positioned along the perimeter at tight intervals (< 200 mm).

A continuous high-tensile steel wire cable coated in clear plastic passes through every single grommet and through dedicated lashing eyelets welded to the container exterior top side rails. The two ends of the TIR wire meet at the door handle closure and are locked together using an official tamper-evident customs bolt seal, ensuring no goods can be added or removed without breaking the cable or leaving noticeable traces.

To safely secure dense, high-mass machinery against axial, lateral, and vertical acceleration forces experienced in sea transit, our 20ft open top units are fabricated with heavy-duty forged steel lashing rings welded directly along the lower internal side sills.

Each standard floor ring delivers a minimum safe working load (SWL) rating of 1,000 kg to 2,000 kg, with heavy-project customization options providing up to 4,000 kg SWL D-rings. Corner post tie-down brackets are also fitted to facilitate cross-bracing of top-heavy industrial assemblies.

Standard units comply fully with ISO 1496-1 and display an updated CSC (International Convention for Safe Containers) safety approval plate valid for international intermodal rail and sea transport. For specialized offshore platform services (such as North Sea or Gulf of Mexico drilling support), we manufacture customized units engineered in strict compliance with DNV GL 2.7-1 / EN 12079 standards, incorporating certified lifting padeyes, internal impact reinforcements, and cryogenic structural steels.
