What is the recommended way to stack slabs at a storage yard?

Slabs should be stacked on their edge, leaning slightly against a sturdy wall or rack, with wooden battens separating them to prevent contact and allow air circulation.

What are the common materials used for packing stone slabs?

The code suggests materials like straw, wood wool, battens, and wooden planks for creating crates and providing cushioning between slabs (Clause 4).

Does this code cover transportation by truck and train?

Yes, the code's principles apply to packing for transportation by lorry (truck), railway wagon, and ship, with considerations for the shocks and vibrations typical of each mode.

This standard provides guidelines for the proper stacking and packing of natural stone slabs for transportation. It covers methods to prevent damage like chipping, scratching, and breakage during handling, loading, transit, and unloading.

Code of practice for stacking and packing stone slabs for transportation

Quick Reference Values

Maximum height of horizontal stack1.5 m

Minimum thickness of separating material (e.g., straw)10 mm

Minimum batten thickness for packing crates25 mm

Recommended inclination for leaning slabs10 to 15 degrees from vertical

Practical Notes

Always stack slabs vertically on their long edge, preferably in A-frames, for transport to minimize bending stress.

Ensure packing materials like straw or paper are completely dry to prevent staining, especially on light-colored or porous stones.

Clearly label crates with weight, handling instructions ('Handle with Care', 'Fragile'), and orientation arrows.
