What are floor slots in a 20ft container?

Floor slots are designated spaces within the container that allow for the secure placement of pallets, ensuring they remain stable during transport.

What does a dimensional weight of 167 kg per cubic meter mean?

A dimensional weight of 167 kg per cubic meter indicates the weight used for billing purposes based on the volume of the cargo, which helps in determining shipping costs.

What is the significance of the payload limit?

The payload limit is a planning figure that indicates the maximum weight of cargo that can be safely loaded into the container, considering its structural integrity and safety regulations.

Each rectangle is one pallet slot on the floor. A second level uses the same footprint when the stackable toggle and the internal height both allow it.

Floor slots are a non-overlapping grid. The count is the better of one orientation, two orientations side by side, or repeated columns across the internal width. Euro 1200×800 mm resolves to 11 slots in a 20 ft dry container and 25 in a 40 ft dry container.

Cartons per pallet are the same grid on the pallet deck, times the layers that fit above a 150 mm deck and below the internal height, with 50 mm of clearance. Stackable freight uses two levels only when both levels fit.

Cargo volume is the carton cube. Volumetric weight is 167 kg per cubic meter. Billable weight is the greater of actual payload, including pallet tare, and volumetric weight. A per-cubic-meter rate uses the carton cube. A per-tonne or per-pound rate uses the billable weight. Payload limits are planning figures, not a carrier scale ticket.

Engineering notes

When using a 20ft container with GMA pallets, it's essential to understand the concept of floor slots. These slots are designed to accommodate the pallets securely, ensuring stability during transport. The dimensional weight of 167 kg per cubic meter is a critical factor in calculating shipping costs and space utilization.

Keep in mind that the payload limit is a planning figure and should be considered alongside the container's maximum gross weight and the weight of the pallets themselves. Proper planning ensures compliance with safety regulations and efficient use of container space.
