20ft Open Top Container Dimensions

Shipping Containers of Birmingham provides high-specification 20ft open top containers for commercial projects throughout the West Midlands. These units serve a distinct purpose for businesses handling cargo that cannot be loaded through standard end doors. Unlike a general-purpose unit, an open-top container features a removable roof system, allowing a crane to lower heavy machinery or bulk materials directly into the container body.

We stock these specialist units for a variety of sectors, including construction, manufacturing, and scrap metal processing. Whether you need to transport oversized equipment or require a unit for bulk storage, our team can help you buy shipping containers for long-term use or arrange a flexible agreement to hire containers for specific projects.

Dimensions and Technical Capacity

Every 20ft open top unit from Shipping Containers of Birmingham adheres to ISO standards. This ensures compatibility with global transport networks. A key part of this compliance is the CSC plate. A CSC plate is a safety certificate fixed to the container that confirms it is fit for international shipping and stacking. If you intend to use the unit for export, we will ensure the plate is valid and the unit meets cargo-worthy standards.

Tare weight describes the weight of the empty container, while payload is the maximum cargo weight allowed. Note that internal measurements can vary slightly between manufacturers. If your load requires millimetre-perfect clearance, contact Shipping Containers of Birmingham to verify the exact dimensions of our current stock.

Core Features of Open Top Containers

The 20ft open top is a versatile tool for heavy logistics. At Shipping Containers of Birmingham, we focus on units that offer maximum utility and safety for the operator.

Removable Roof Bows and Tarpaulin

The container's roof consists of removable steel bars known as roof bows. These bars support a heavy-duty, reinforced PVC tarpaulin. Once the tarpaulin is removed and the bows are lifted out, the top is entirely clear for crane access. The tarpaulin is secured using a TIR cable, creating a wind and watertight (WWT) environment. Wind and watertight means the unit prevents rain and wind from entering, keeping your cargo dry during transit or storage.

Swivel Header Bar

Many of our units feature a swivel or removable rear header bar. This bar sits above the rear doors. By swinging the header out of the way, you can load tall items, such as forklift masts or large crates, through the end doors without being limited by the container's top frame. This is a vital feature for machinery that is slightly too tall for standard door heights but does not require crane loading.

Heavy Duty Floor and Lashing Points

Open-top containers typically carry dense, heavy items that create significant point loads. The floors are reinforced to handle this stress. Shipping Containers of Birmingham provides units with multiple lashing points. These are steel rings welded into the structure used to strap down cargo. This prevents movement during sea or road transport, which is essential for safety and compliance.

Site Delivery and Positioning in Birmingham

We deliver all containers using HIAB vehicles. A HIAB is a truck with a built-in hydraulic crane. This allows us to lift the 20ft unit over fences or walls and place it precisely on your site. For a successful delivery, you must ensure the ground is level and firm. Concrete, tarmac, or compacted gravel are the best surfaces. We do not recommend placing containers on soft grass as the weight will cause the unit to sink, leading to door alignment issues.

You should also consider local regulations. While containers are often viewed as temporary structures, some placements in the Midlands may require permission. We recommend checking with your local council via the UK Planning Portal to ensure you remain compliant with local building and land-use rules.

Choosing 20ft vs 40ft Open Tops

If your cargo is longer than 19 feet, you will need a 40ft open top container. However, the 20ft unit is often the preferred choice for heavy, dense materials like stone, ore, or steel parts. This is because the weight limit of a container is often reached before the volume is full. A 20ft unit is also easier to deliver to sites with restricted access in busy Birmingham city centre locations.
