ISO 9001 Quality Seal

The entire line of Giannini strings has the approval of the ISO 9001quality seal. But what is the ISO 9001 seal?

ISO 9001 is a series of norms and rules that seek to guarantee the final quality of your strings. These procedures range from the choice of the raw material and its suppliers, going through the entire production process of the strings, training of the labor involved in the production, its distribution, until the product reaches the dealers and the consumer. These processes and all those involved in it undergo audits every year, to verify that they are being followed according to the established standard, so that the seal is renewed.

Since 2007, Giannini has been awarded the ISO 9001 seal in its strings line, which is renewed annually, proving the quality of each string that you use in your instrument.
