The main body is constructed from SPA-H high-strength, weather-resistant corrugated steel. Key structural areas—including the four corners and bottom side rails—are thickened and reinforced, and the unit features anti-corrosion and anti-rust coatings to meet rigorous standards for multi-layer port stacking and long-haul maritime transport. Heavy-duty lashing rings are evenly distributed along the interior sidewalls and floor, allowing for the secure anchoring of heavy cargo—such as large machinery and steel products—to prevent shifting or movement during transit.
The unit is equipped with a removable metal roof arch framework and a heavy-duty, anti-aging PVC waterproof tarpaulin. This cover is rainproof, sun-resistant, and tear-resistant, and can be either fully rolled up or completely detached. Multiple tensioning buckles along the sides ensure a fully sealed, waterproof fit, effectively protecting cargo from the elements during adverse weather.
The rear door header beam is fully detachable, widening the rear loading/unloading access point and accommodating both side-loading (via forklift) and top-loading (via crane) operations. The door panels utilize a dual-locking bar sealing mechanism, with high-quality gaskets ensuring a watertight and dustproof seal.
Standard units come with birch plywood flooring, suitable for transporting general equipment and construction materials. For heavy-duty applications, an all-steel floor option is available, making the container ideal for transporting steel coils, scrap metal, and heavy construction machinery.

With no rigid roof constraints, cranes can load cargo directly into the container from above, overcoming the limitations of standard dry containers that rely on rear-door access and cannot accommodate oversized, extra-tall items. Cargo height can moderately exceed the container's top edge (when the tarpaulin is removed), significantly expanding the scope of oversized cargo transport.
Compared to hard-top open-top containers, the soft-top structure is lighter, reducing costs associated with empty container transport. The tarpaulin is easy to install and remove without heavy machinery, shortening terminal handling times and offering advantages in procurement and maintenance costs.
Suitable for the maritime export of oversized equipment, stone, glass, and steel, as well as for inland rail and short-haul road transport. On return trips, the container can carry general bulk or packaged cargo, avoiding the waste of empty returns and improving container turnover and utilization rates.
When closed, the tarpaulin provides comprehensive waterproofing and UV protection, withstanding rain and sun exposure during sea voyages. The removable tarpaulin facilitates routine inspections and interior cleaning, extending the container's service life.
