What Is an Open Top Container?
An open top container is a specialized type of shipping container that features a removable roof instead of the permanent steel top found on standard dry storage units. While the walls and floor are constructed from the same corrugated steel as conventional containers, the top is left open and covered with a heavy-duty tarpaulin — commonly called a “tilt” — that can be secured in place or fully removed.
This design makes open top containers the go-to solution for cargo that is too tall, too heavy, or too oddly shaped to be loaded through the standard end doors of a regular container. Cranes, forklifts, and overhead gantries can lower items directly into the container from above, eliminating the challenges of horizontal loading.
Open top containers are available in the same standard footprints as conventional shipping containers — primarily 20-foot and 40-foot lengths — and they conform to ISO shipping standards, meaning they can be transported by sea, rail, and truck using the same handling infrastructure as any other intermodal container.
Open top containers combine the structural strength and weather resistance of standard steel containers with the loading flexibility of an open roof. They are essential for any shipment where cargo dimensions or weight make top-loading the only practical option.
Open Top Container Dimensions (20ft & 40ft)
Choosing the right size is one of the most important decisions when selecting an open top container. The two most common sizes — 20-foot and 40-foot — each serve different cargo requirements. Below you’ll find the complete dimensional specifications for both.
20ft Open Top Container Dimensions

Note: Interior dimensions may vary slightly between manufacturers. Always confirm exact measurements with your supplier before loading.
If your cargo is tall but doesn’t exceed standard container width, a high-cube open top container gives you an extra 12 inches of vertical clearance without changing the footprint. This can be the difference between needing out-of-gauge surcharges and fitting inside the container walls.
7 Types of Open Top Containers
Not all open top containers are built the same. Depending on your cargo, budget, and transport requirements, one of these seven types will be the best fit for your project.
1. Standard Open Top Container
The most widely available type, built with corrugated steel walls and a removable tarpaulin cover. These containers closely resemble standard dry storage units except for the open roof. They’re the default choice for most oversized or top-loaded cargo.
2. Hard Top Open Top Container
Instead of a tarpaulin, these units feature a removable steel roof panel secured with nuts and bolts. The hard top offers better protection against impact, weather, and tampering compared to a fabric cover, but it requires mechanical assistance (such as a crane) to remove and reinstall.
3. Open Top Flat Rack Container
These combine an open top with open or collapsible sides, leaving only the front and rear end walls for structure. Essentially a heavy-duty platform with end walls, they allow loading from the top and from both sides.
4. Open Top High Cube Container
Identical to standard open top containers but with an extra foot of height, bringing the exterior height to 9 feet 6 inches. This additional vertical clearance accommodates taller cargo without the need for out-of-gauge surcharges.
5. Open Top Half-Height Container
These are shorter than standard open top containers and are built with reinforced steel to handle extremely dense, heavy loads. Their reduced height makes them easier to load and more stable when carrying dense materials.
6. Open Top Reefer Container
A refrigerated container with an open top, designed for perishable goods that also require top-loading capability. These units maintain temperature control while allowing oversized perishable items to be loaded from above.
7. Open Top Tank Container
Specialized containers designed for transporting liquids, gases, or granulated materials. They feature an open top for filling and are often custom-built to meet specific industry requirements and safety regulations.
Each container type has different availability in the market. Standard and hard top open top containers are the easiest to source, while specialty types like reefer and tank models may require longer lead times and higher costs. Always consult with a supplier to confirm availability for your specific location and timeline.
Common Uses and Industries
Open top containers serve a wide range of industries where standard enclosed containers simply cannot accommodate the size, weight, or shape of the cargo. Here are the primary applications:
Industries That Rely on Open Top Containers
Construction: Transporting steel beams, prefabricated wall panels, concrete forms, heavy equipment, and other materials that are too long or heavy for standard container doors.
Mining and Resources: Moving bulk minerals, ore, coal, gravel, and heavy rock samples. Half-height open top containers are especially popular in this sector due to their reinforced construction and ease of loading with excavators and dump trucks.
Manufacturing: Shipping large machinery, industrial presses, generators, turbines, and factory equipment that must be lowered into place by crane.
Energy and Utilities: Transporting wind turbine components, transformer units, large cable spools, and pipeline sections.
Agriculture and Forestry: Moving large trees, timber logs, and bulk agricultural products that exceed the dimensions of standard containers.
Cargo Types Commonly Shipped in Open Top Containers
The following cargo types are routinely shipped in open top containers: heavy machinery and industrial equipment, long steel bars and pipes, spools of wire and cable, scrap metal and recycling materials, bulk commodities like coal and minerals, timber and wood logs, glass slabs and construction panels, large vehicles and vehicle components, and oversized generators or engines.
Use an open top container if your cargo meets any of these criteria: it stands taller than 7’10” (the usable interior height of a standard 20ft container), it weighs too much to slide through end doors and must be crane-loaded from above, or it has an irregular shape that prevents horizontal loading.

Compare QuotesHow Much Do Open Top Containers Cost?
The cost of open top containers varies based on size, condition, location, current supply and demand, and any custom features or modifications. Because open top containers are more specialized and less common than standard dry storage units, they typically carry a premium.
Buying Prices
| Size | New | Used (Cargo-Worthy) |
|---|---|---|
| 20ft Open Top | $4,500 – $7,800 | $2,500 – $4,000 |
| 40ft Open Top | $6,700 – $10,000 | $4,300 – $7,600 |
Customizations such as specialized locking mechanisms, reinforced flooring, additional side doors, or non-standard paint can add several hundred to several thousand dollars to the base price.
Rental Prices
| Size | Short-Term (Monthly) | Long-Term (Monthly, 6+ months) |
|---|---|---|
| 20ft Open Top | $125 – $250 | $106 – $213 (5-15% discount) |
| 40ft Open Top | $175 – $350 | $149 – $298 (5-15% discount) |
Delivery Costs
Delivery fees are separate from the container purchase or rental price and depend primarily on distance. Local delivery (under 50 miles) typically runs $160 to $500. For longer distances, expect to pay $400 to $2,000+, depending on the route, road access, and whether specialized equipment like a tilt-bed trailer is required.
Factors That Affect Open Top Container Pricing
Several factors influence what you’ll actually pay: container age and condition (new, cargo-worthy, wind-and-watertight, or as-is), your geographic location and proximity to major ports or depots, current market supply and demand for open top units, the container size and whether it’s standard or high-cube, and any additional features or modifications you require.

Compare Open Top Container QuotesRenting vs. Buying: Which Is Right for You?
Whether you should rent or buy an open top container depends on how long you need it, your budget, and how you plan to use it. Here’s a side-by-side comparison to help you decide.
Advantages of Renting
- Low upfront cost
- Flexibility to change sizes
- No long-term maintenance costs
- Ideal for projects under 18 months
- Supplier handles repairs
Advantages of Buying
- Lower total cost over 18+ months
- Customize without restrictions
- Resale value when finished
- No monthly payments
- Full control of the asset
Break-Even Analysis
At an average monthly rental rate of $175 for a 20ft open top container, you would spend approximately $3,150 over 18 months — roughly the cost of buying a used unit outright. If you need the container for more than 18 months, buying almost always makes better financial sense. For projects under 12 months, renting is typically the more economical choice.
Rent if you need the container for less than 18 months, want zero maintenance responsibility, or need to test different sizes before committing. Buy if you need it for more than 18 months, want the freedom to customize, or plan to resell the container later.
How Open Top Containers Are Loaded
One of the primary advantages of open top containers is their loading versatility. Unlike standard containers that can only be loaded through the end doors, open tops offer multiple access points.
Top Loading
The most common method involves removing the tarpaulin cover and roof bows, then using an overhead crane, gantry, or hoist to lower cargo vertically into the container from above. This is the preferred method for heavy or bulky items that cannot be tilted or slid into place. Top loading is especially efficient at port terminals and construction sites where crane access is readily available.
Rear Door Loading
Open top containers retain the same double-door configuration at one end as standard containers. The door header beam on many models is designed to swing open or detach completely, creating a taller door opening for forklifts and taller cargo. This means standard palletized freight can still be loaded conventionally.
Combination Loading
For mixed shipments, you can load some items through the doors and others from the top. This flexibility is particularly valuable when shipping a combination of standard palletized goods alongside one or two oversized pieces.
Always secure cargo using the lashing rings welded to the interior floor and lower sidewalls. Heavy items should be centered over the container’s structural crossmembers. If cargo will protrude above the container walls, coordinate with your shipping line in advance — out-of-gauge freight requires special stowage planning and will incur additional surcharges.
Protecting Cargo in Open Top Containers
Since open top containers lack a permanent steel roof, protecting cargo from weather, theft, and shifting during transit requires specific measures.
Tarpaulin Cover
The primary protective element is the tarpaulin (tilt) — a heavy-duty cover made from PVC-coated canvas or industrial-grade polyester. Modern tarpaulins are waterproof, UV-resistant, and designed to withstand sustained wind exposure during ocean transit. The cover is stretched over removable steel roof bows and secured to the container’s top rails using clamps or rope tensioning systems.
TIR Cable and Customs Sealing
A steel TIR cable threads through eyelets in the tarpaulin and locks to the container frame, allowing customs officials to seal the container for international transit. This system ensures the tarpaulin cannot be removed without breaking the customs seal, providing tamper-evident security throughout the shipping journey.
Lashing and Securing
Interior lashing rings — typically welded to the floor and lower walls at regular intervals — provide anchor points for straps, chains, and ratchet tie-downs. Proper lashing prevents cargo from shifting during the accelerations, decelerations, and lateral forces experienced during truck, rail, and ocean transport.
Weather Protection Limitations
While tarpaulins provide effective rain and wind protection, they do not offer the same level of weather resistance as a solid steel roof. For cargo that is sensitive to moisture, condensation, or temperature fluctuations, consider adding internal moisture barriers, desiccant packs, or shrink-wrap as supplementary protection.
Key Components and Construction
Understanding the structural components of an open top container helps you assess quality, compare models, and make informed purchasing decisions. Here are the critical parts:
Corrugated Steel Walls: The side and end walls are made from the same heavy-gauge corrugated steel used in standard containers, providing structural rigidity and weather resistance. The corrugation pattern adds strength without excessive weight.
Hardwood or Bamboo Flooring: The container floor is built from marine-grade plywood or treated hardwood planking over steel crossmembers. This combination supports heavy loads while providing a surface suitable for forklift operations.
Roof Bows: These removable steel bars span the width of the container and support the tarpaulin cover. They also contribute to the structural rigidity of the container walls. Removing the bows creates a fully open loading area.
Swinging Door Header: The steel beam above the rear doors can be swung open or detached on many models, increasing the effective door opening height for loading taller items.
Corner Posts and Castings: Heavy-duty steel corner posts and ISO-standard corner castings enable the container to be lifted, stacked, and locked onto truck chassis, rail cars, and ship cell guides.
Lashing Rings: Steel D-rings welded to the floor and lower walls at regular intervals serve as anchor points for cargo securing equipment.
Forklift Pockets: Reinforced channels in the base allow forklifts to lift and position the container.
Expert Tips for Buying Open Top Containers
Whether you’re purchasing your first open top container or adding to a fleet, these practical tips will help you make a smarter investment.
1. Verify Structural Integrity
Inspect the corner posts, floor crossmembers, and wall panels for signs of rust, dents, or weld cracks. Pay particular attention to the top rail where the tarpaulin attaches — corrosion here can compromise the seal and make it difficult to secure the cover properly.
2. Check the Tarpaulin and Roof Bows
A replacement tarpaulin can cost $300 to $800 depending on the container size, so check the existing cover for tears, UV degradation, and failed grommets. Verify that all roof bows are present and that they seat properly in their brackets.
3. Test All Doors and Locking Mechanisms
Open and close the rear doors to check for smooth operation. Inspect the locking bars, cam handles, and gaskets. Doors that are difficult to operate may indicate frame distortion, which is a significant structural concern.
4. Understand Container Grading
Containers are typically graded as new/one-trip (essentially new, used for a single voyage), cargo-worthy (CW) (certified for ocean shipping), wind-and-watertight (WWT) (weatherproof but not certified for ocean freight), or as-is (sold without guarantees). Match the grade to your intended use — you don’t need a cargo-worthy certification if the container will be used for stationary storage.
5. Get Multiple Quotes
Prices for the same container grade and size can vary by 15% to 30% between suppliers, especially in areas away from major ports. Always compare at least three quotes before committing.
6. Factor in Total Cost of Ownership
Beyond the purchase price, account for delivery fees, site preparation (a level surface is essential), any modifications you need, and ongoing maintenance like repainting or tarpaulin replacement.

Open top containers are primarily used for transporting oversized, tall, or awkwardly shaped cargo that cannot fit in a standard enclosed container. Common uses include shipping heavy machinery, timber, steel beams, construction materials, pipes, scrap metal, and bulk cargo like coal or minerals. They are widely used in the construction, mining, manufacturing, and energy industries.
A new 20ft open top container costs between $4,500 and $7,800, while a new 40ft model ranges from $6,700 to $10,000. Used 20ft units are available for $2,500 to $4,000, and used 40ft containers cost $4,300 to $7,600. Monthly rental rates start around $125 for a 20ft unit and $175 for a 40ft unit. See the full pricing breakdown above for more details.
The most common sizes are 20-foot and 40-foot lengths, matching the standard shipping container footprints. Both sizes are available in standard height (8’6″) and high-cube (9’6″) configurations. Half-height open top containers are also available in 10ft to 20ft lengths for dense, heavy cargo. See the dimensions section for complete specifications.
Open top containers come with a heavy-duty tarpaulin cover made from waterproof PVC or canvas. The tarpaulin is secured by removable roof bows and specialized clamps. A TIR cable provides customs-sealed security. Inside the container, lashing rings on the floor and walls allow cargo to be strapped down securely. For moisture-sensitive goods, additional protection like desiccant packs or shrink-wrap is recommended.
Yes, open top containers can be stacked if the cargo sits level with or below the container walls. However, if cargo protrudes above the walls (out-of-gauge), stacking is not possible, and the container must be stored and shipped separately. This typically increases shipping costs because it occupies space where other containers could otherwise be stacked.
Renting is more affordable for short-term needs (under 18 months). Monthly rates start around $125 for a 20ft container. Buying becomes more cost-effective if you need the container for longer than 18 months, since a used 20ft open top can be purchased for $2,500 to $4,000 — roughly the same as 18 months of rental payments. Long-term renters may negotiate 5% to 15% discounts on monthly rates.
Technically, it is possible to convert a standard container into an open top by cutting and removing the roof. However, this is a significant structural modification that can compromise the container’s load-bearing capacity and integrity. Professional engineering design and safety compliance are required. In most cases, purchasing or renting a purpose-built open top container is more practical, safer, and more cost-effective.
An open top container has four solid steel walls with no fixed roof, while a flat rack container has only two end walls (sometimes collapsible) with no side walls or roof. Open tops are better for tall cargo that benefits from side protection, while flat racks are better for extremely wide or irregularly shaped loads that need to be loaded from the sides. Both types accommodate crane loading from above.
Items can be loaded from above using cranes, overhead gantries, or forklifts after removing the tarpaulin and roof bows. Open top containers also have standard rear doors, and many models feature a swinging door header beam that creates a taller door opening. This flexibility allows for top loading, rear loading, or a combination of both methods depending on the cargo.
Yes, open top containers are typically more expensive than standard dry storage containers, both to purchase and to ship. The higher cost is due to their specialized construction (including roof bows, tarpaulin systems, and modified headers) and lower availability in the market. Shipping costs can increase further if cargo protrudes above the container walls, as this prevents stacking and takes up additional vessel space.
