What is the Maximum Number of Granite Slabs a Shipping Container Can Hold?
Granite is one of the most popular natural stones in the world, known for its strength, durability, and aesthetic appeal. It’s used in everything from kitchen countertops to flooring, and with the rising global demand for granite, transportation logistics have become a significant consideration for importers, suppliers, and manufacturers. A common question in the granite export and import industry is, “How many granite slabs can a shipping container hold?” The answer depends on various factors, such as the type of granite, the thickness of the slabs, the size of the container, and weight restrictions. Let’s explore these factors in more detail to understand how granite slabs are loaded into shipping containers and what limits the number of slabs that can be shipped.
The General Details Regarding A 20-foot Container’s Storage Capacity Are Provided Below.
| Big Slabs | No. of Piece | Small Slabs | No. Of Piece |
|---|---|---|---|
| 2 cm Thickness slabs | 80 To 85 Pieces | 2 cm Thickness slabs | 200 To 250 Pieces |
| 3 cm Thickness Slabs | 50 To 55 Pieces | 3 cm Thickness Slabs | 110 To 125 Pieces |

The Shipping Container Sizes
Shipping containers come in a variety of sizes, but the most common types used for transporting granite are 20-foot and 40-foot containers. These are standard sizes in the shipping industry, and they are often the best option for transporting granite slabs efficiently.
20-foot container: A 20-foot shipping container typically measures 20 feet in length, 8 feet in width, and 8.5 feet in height. The capacity of this container is approximately 33 cubic meters or 1,170 cubic feet.
40-foot container: A 40-foot shipping container is double the length of a 20-foot container, measuring 40 feet in length, 8 feet in width, and 8.5 feet in height. The capacity is about 67 cubic meters or 2,350 cubic feet.
The container’s internal dimensions, however, are not the only factor to consider when determining how many granite slabs can fit inside.
Granite Slab Thickness and Size
The thickness of granite slabs plays a crucial role in how many can be packed into a container. The most common thicknesses of granite slabs are 2 cm and 3 cm. Thicker slabs are heavier and bulkier, meaning fewer slabs will fit in a container compared to thinner slabs.
2 cm thick slabs: These slabs are lighter and easier to stack efficiently, allowing more slabs to fit into a container. Since they are thinner, they take up less space and are typically more flexible for loading.
3 cm thick slabs: These slabs are heavier and bulkier. As a result, fewer 3 cm slabs can be loaded into the same-sized container. However, 3 cm granite slabs are preferred for certain applications due to their durability.
Granite slabs are usually processed into different formats, such as gangsaw slabs, cutter slabs, or tiles. Gangsaw slabs are the largest and typically the heaviest, so these will take up more space in the container compared to smaller slabs or tiles.
Weight Restrictions
Granite is a heavy material, and weight is an important factor when determining how many slabs can fit into a shipping container. Most shipping containers have weight restrictions, and exceeding these limits can result in additional costs or the inability to ship the container. For example, the typical weight limit for a 20-foot container is around 24,000 to 26,000 kg (52,900 to 57,300 lbs), while a 40-foot container can hold between 26,000 and 28,000 kg (57,300 to 61,700 lbs).
In the United States, a tri-axle vehicle typically has a weight limit of 44,000 lbs (19,900 kg), and this is important to consider when shipping granite from overseas. The weight of the granite slabs, along with the packaging materials and container, must fall within these weight limits.
For example, granite slabs that are 2 cm thick will weigh less than 3 cm slabs. Consequently, more 2 cm slabs can fit into a container, as they take up less space and weight. A typical 20-foot container can hold approximately 70–75 slabs of 2 cm thickness, while it would only hold about 50–52 slabs of 3 cm thickness.
Number of Granite Slabs in a Container
To better understand how many granite slabs a shipping container can hold, let’s break it down:
2 cm thick granite slabs: A 20-foot container can typically hold between 70 and 75 slabs of 2 cm thickness. A 40-foot container would hold approximately 140 to 150 slabs, depending on the weight distribution and space optimization.
3 cm thick granite slabs: A 20-foot container would hold about 50 to 52 slabs of 3 cm thickness, while a 40-foot container would hold around 100 to 104 slabs.
In both cases, the slabs are usually packed into bundles to ensure that they are well-protected during transit. A bundle typically consists of 5 to 7 slabs, depending on the thickness.
The slabs are then securely strapped together to ensure they remain stable throughout the journey. This careful packing method is essential to ensure that the granite arrives at its destination in pristine condition, ready for installation.
Loading and Packaging
Loading granite slabs into a shipping container requires careful planning and attention to detail. Granite slabs are heavy and fragile, so they must be packed securely to avoid any damage during transportation. Shipping companies and exporters use specialized wooden crates or metal frames to protect the slabs during the journey. The slabs are often secured with strapping or padding to prevent movement and minimize the risk of breakage. These bundles are often wrapped in protective layers, such as foam padding or shrink wrap, to shield the slabs from scratches, dust, and moisture.
In Conclusion
The number of granite slabs that a shipping container can hold depends on several key factors, including the thickness of the slabs, the weight restrictions, and the size of the container. Typically, a standard 20-foot container can hold between 50 to 75 slabs, with the exact number varying depending on whether the slabs are 2 cm or 3 cm thick. Proper planning and careful packing are essential to maximize container space and ensure the slabs are securely transported without damage. By understanding these variables, importers and exporters can efficiently manage shipments and ensure that their granite arrives safely at its destination.
