ISO 9001:2008

ISO 9001 is made up of 19 sets of standards for quality assurance in production, installation and servicing. This model applies to organizations that produce, install and service products. ISO expects organizations with the ISO registration to apply this model and to meet these requirements by developing a quality system.

ISO 9001 is a comprehensive set of requirements that governs the production of materials. The standard includes requirements that encompass all areas of production from the mill. A mill attaining ISO 9001 registry has a complete quality system in place. Compliance to ISO 9001 assures the customer that the material they receive consistently meets the most stringent quality standards.
