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.
Below: 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 and it states documents must be corss 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 securityThe BSIA (British Security Industry Asscociation) promotes the shredding standard EN15713 which defines various shred sizes. A less used but very improtant standard is DIN 66399.
