Applications
Applications for 20ft High Cube Steel Floor Container
The strongest use cases for this specification, based on its configuration and published selection criteria.
Best fit
Heavy rolling loads
The steel checker-plate floor is designed for durable handling of wheeled equipment and rolling cargo, subject to rated floor and axle loads.
Selection criterion
Moisture-resistant flooring
Unlike a timber or bamboo-composite floor, the steel surface does not absorb moisture; coating condition, drainage, and corrosion control remain important.
Selection criterion
Non-absorbent floor surface
The steel checker-plate surface is non-absorbent, making it better suited to damp equipment and packaged liquids than a timber-based floor.
Selection criterion
High wear resistance
The steel checker-plate floor provides a hard-wearing surface for intensive loading and repeated operational use.
Selection criterion
Reduced-combustible floor surface
The steel floor removes timber or bamboo floor material from the loading surface where reduced combustible content is a selection priority.
Selection criterion
Cargo restraint
Standard floor-level lashing rings provide restraint points for securing general cargo during transport; use certified equipment and remain within the marked lashing capacity.
Application
Equipment storage
Storage for tools, machinery, and operational equipment.
Selection criterion
Frequent relocation
ISO freight construction, corner castings, and the Corten-steel shell are designed for repeated lifting, transport, and redeployment. On white variants, the PU coating adds paint durability that helps the container remain presentable.
Application
General cargo
Transport and storage of general dry cargo.
Application
Palletised cargo
Transport and storage of palletised goods and unitised freight.
Application
International shipping
Cross-border and intercontinental transport using ISO freight containers.
Selection criterion
Heavy point loads
Steel flooring is a stronger starting point for concentrated machinery loads, but point loads still require confirmation against the floor rating and may need load-spreading plates.
Application
High-volume storage
Storage where additional internal height and cubic capacity are important.
Application
Temporary warehousing
Flexible short- or medium-term warehousing without constructing a permanent building.
Application
Inventory overflow
Additional capacity for seasonal stock, production peaks, and warehouse overflow.
Selection criterion
Easy spill cleanup
The non-absorbent steel surface can be wiped or washed after minor leaks and spills, subject to safe containment and disposal procedures.

Technical questions
Frequently checked details
Direct answers based on the published values in this specification record.
This SF configuration suits equipment storage, general cargo, palletised freight, international shipping, high-volume storage, temporary warehousing, and inventory overflow. The steel checker-plate floor makes it a best fit for forklift traffic, heavy rolling loads, moisture-resistant needs, non-absorbent surfaces, high wear resistance, and reduced-combustible requirements.
Internal length is 5898 mm, width 2352 mm, and height 2698 mm. The front double cargo doors open 2340 mm wide by 2580 mm high with easy-open locking bars and a lockbox. Forklift pockets are fitted for handling.
Tare weight is 2370 kg, payload is 28110 kg, and maximum gross mass is 30480 kg. These are the published container weight values; road, rail, vessel, axle, and route limits are separate operational considerations.
The SF configuration substitutes a steel checker-plate floor for the standard timber or bamboo floor, adding durability for heavy and frequent loading. The LR moving container carries lashing rails for furniture and equipment restraint instead. Both share the same 6058 mm by 2438 mm by 2896 mm external dimensions and front double cargo door layout as the base 20HC-25G1-S01, though the SF's tare is higher and payload slightly lower at 28110 kg versus 28330 kg.
Design approval is held under type approval, and plates are supplied with an assigned-per-unit examination scheme. The individual unit's current plate and examination status must be checked before shipping use.
Small quantities can be repainted in a requested color. Larger production batches can be ordered in specific colors and can include project or company branding, subject to order requirements and confirmation.
The steel checker-plate floor is a stronger starting point for concentrated loads, but heavy point loads still require confirmation against the floor rating and may need load-spreading plates. Standard floor-level lashing rings provide restraint points; use certified equipment and remain within marked lashing capacity.
