Common Sintered Stone Slab Weights
Weights are planning estimates based on a typical density of 2,450 kg/m³. Actual batch weight may vary slightly by product series, finish, and manufacturing tolerance.

Method and assumptions
How the weight calculation works
Use the formula and assumptions below to understand what the calculator includes, what the result means, and which figures still require order-specific confirmation.
Material weight formula
Slab net weight is calculated from the finished slab dimensions, selected thickness, and the planning density used by this tool.
Width × Length × Thickness × Density = Net Slab Weight
Dimensions are converted to metres before calculation. Thickness must therefore be entered as metres in the formula, for example 12 mm = 0.012 m.
Worked example: 1600 × 3200 × 12 mm
For one 5.12 m² slab using the calculator density of 2,450 kg/m³:
1.6 m × 3.2 m × 0.012 m × 2,450 kg/m³ = 150.528 kg
≈ 150.5 kg net per slab
A planning example of 25 slabs on one 150 kg steel A-frame gives approximately 3,913.2 kg cargo gross weight before any additional protection or accessories.
Density reference: 2,450 kg/m³
A consistent planning value used for comparison. Confirm the actual product technical data when a precise shipping or structural figure is required.
Net material weight
The weight of the sintered stone only. It excludes A-frames, spacers, protective material, straps, accessories, and the container tare weight.
Estimated cargo gross weight
Net slab weight plus the selected packing estimate. It is not the certified gross mass or final carrier-approved payload.
Container and A-frame planning
Compare 20ft and 40ft loading references
These factory layout references show how A-frame count and slabs per frame affect physical capacity for 1600 × 3200 mm slabs. The active calculator also applies the selected cargo weight limit.
40ft GP

9 mm34 slabs per frame · 374 slabs · 1,914.88 m² physical layout reference
12 mm25 slabs per frame · 275 slabs · 1,408.00 m² physical layout reference
01Define the slab mixConfirm each size, thickness, finish, and quantity before assigning frames.
02Build the A-frame planAllocate slabs per frame and include the actual or estimated A-frame tare weight.
03Apply the cargo limitCompare the physical layout with the selected payload limit; the lower result controls planning.
04Confirm the routeCarrier, container condition, port, destination, and inland transport rules still require approval.
Container loading disclaimer: A factory layout reference describes a possible physical arrangement, not a guaranteed legal payload. Final A-frame configuration, verified mass, carrier acceptance, route limits, loading method, and destination rules must be confirmed before shipment.

Sintered Stone Weight Calculator FAQ
Is 2,450 kg/m³ the exact density of every sintered stone slab?
No. It is the planning density used by this calculator. Actual density and finished slab weight can vary by product body, finish, manufacturing tolerance, and batch, so use the product technical data for final verification.
What is the difference between net slab weight and cargo gross weight?
Net slab weight covers the sintered stone only. Estimated cargo gross weight adds the selected A-frame or custom packing estimate, but it does not include the container tare weight and is not a certified gross mass.
Does a 40ft container always carry more slabs than a 20ft container?
Not necessarily. A 40ft container has more physical space, but the usable payload may not increase in the same proportion. The cargo weight limit, A-frame layout, carrier rules, route, and inland transport restrictions can reduce the active loading quantity.
How are slabs per A-frame and A-frame quantity selected?
They depend on slab dimensions, thickness, surface protection, frame design, unloading method, and factory loading layout. The calculator provides editable planning inputs; the factory must confirm the final frame configuration.
Can different sizes, thicknesses, or colours share one container?
They may be combined, but a mixed load needs a specification-by-specification packing review. Different formats can change frame allocation, protection, centre of gravity, unloading sequence, and the usable slab count.
What information is required before a loading plan can be approved?
Provide slab size, thickness, finish, quantity, destination, packing requirement, and any mixed-load details. Final approval also depends on the actual packing design, verified weights, carrier acceptance, and destination transport rules.
