Cross-cut shredding involves a secondary action that cuts strips like those an office shredder would cut, into much smaller fragments. Shred size does matter – the smaller the fragments the higher the security. Read on to find out more.
What is cross-cut shredding?
Cross-cut (or confetti shredding) is a method of paper shredding that involves cutting the paper in two directions, horizontally and vertically to increase the security level of the shredding process. The BSIA (British Security Industry Association) promotes the shredding standard EN15713 which defines various shred sizes. A less used but very important standard is DIN 66399.
What is the best type of paper shredder?
Standard shredding, where documents are cut into strips, is fine for normal commercial paperwork. Shred size for this type of shredder is typically 2000 sq mm. Cross-cut shredding involves a secondary action that cuts the strips into much smaller fragments, which is required by organisations such as NHS general practices and Ministry of Justice.
Topwood’s shred trucks are all fitted with the highest security shredders with the capability to shred to standard EN15713. By using mobile shred trucks, security is increased as a shred truck full of standard shredded paper contains over 50 million, small sized, shredded fragments that when mixed together makes any reconstruction impossible.

Office Shredder “Strip Cut” next to our high security “cross-cut” shredding.
High security fragments: Approx 2mm-8mm sq 750 million shredded fragments per truck load. It would be impossible to locate and reconstruct a document from these fragments.
Office shredded strips tend to leave office premises in bin bags; there may be only 300 strips per bin bag, which makes it far more likely that a document can be reconstructed.

Topwood Shredding offers a choice of shred size depending on your industry’s requirements. How do you know what shred size you need?
A standard shred size is suitable for most commercially sensitive documents. However, regulations and corporate governance can stipulate higher security levels. When destroying restricted or classified documents a smaller shred size can be specified. For example, the UK Government’s CPNI standard covers the destruction of sensitive documents on behalf of government departments like the Ministry of Justice as well as NHS GP practices and it states documents must be cross-cut.
Our destruction process uses state of the art shredders that completely destroy unwanted documents. In the UK the most referred to shredding standard is EN15713 but other standards for measuring shred size are used. For example the DIN Classification 66399 classifies shred sizes from P1 (largest) to P7 and is used in the specifications of office shredders.
Unlike most shredding companies we have shred trucks that will cross cut documents for maximum security
