Stainless steel industry in the non-standard plate, non-standard What does this mean?
Non-standard is the industry standard. General things have GB, but the industry has its own standard, called the industry standard

In the national standard, the product specifications, the content range of the elements and many other indicators are made in detail, which also includes the approval of the implementation of the country, the standard standards and industry standards, but without the factory standard, that is, Factory-defined standards,
If the relevant provisions do not meet these standards as a substandard product,
But sometimes these standards within the provisions of the product can not meet the needs of the use of units, such as a user can only use thick 9mm board, but the product standard series is not, only with manufacturers agreed to special processing, this product is called non-standard , But also the quality of processing failed, but some manufacturing can also be used, or downgrade also known as these non-standard products,
GB3280-1984 is a stainless steel plate of the national standard

Because steel mill rolling stainless steel coil has a set of standards, respectively, the thickness tolerance and width tolerance, tolerance within the standard plate is the standard sheet, and the thickness of the tolerance and width is not within the standard called non-standard plate. Such as width, generally four feet 1219 of the edge or burr, 1000 of the edge or burr, but the customer needs to order the steel to other thickness of the other are called non-standard plate.
