Rowmark LLC Achieves Recertification of ISO 9001

FINDLAY, OH – Rowmark, the leading supplier of extruded and laminated plastic sheet materials for the signage, engraving industry, and its custom division PMC (Premier Material Concepts), an extruder of custom plastic sheet and roll stock for the thermoforming industry, have completed recertification of ISO 9001 Quality Management System. Rowmark is the only engravable plastic sheet manufacturer that adheres to the rigorous requirements of ISO 9001.

A key element of ISO 9001 is mandatory certification by an independent, accredited auditor. ISO certification means that Rowmark continues to implement business processes and procedures that ensure the highest quality performance in all aspects of the quality management system.

For nearly 30 years, Rowmark has been a leading provider of world-class extruded and laminated custom plastic sheet and roll stock for the signage, engraving, thermoforming and other industries and has been the industry’s preferred choice across the globe.

Rowmark first received ISO 9001 certification in December 2004. The most important aspect of ISO certification is striving for continuous improvement in processes and product quality standards to meet and exceed customers’ expectations.

“It’s simply the way we strive to operate,” said Duane Jebbett, Rowmark President and CEO. “We have been an ISO certified company for over a decade. We received feedback from the auditors that our team was easy to work with, very knowledgeable in quality management principles, and well organized. These are all important values to be able to consistently produce high quality products and services.

ISO 9001 (International Organization for Standardization) is the world's most widely used standard for quality management systems and is an independent, non-governmental international organization with a membership of 163 national standards bodies.
