ISO 9001

	Aiming to Become the Global Quality Standard for Cable Trays Regarding the "manufacture of cable trays," our quality management system has been registered as conforming to the requirements of the ISO 9001 series standards. The registered quality system has supported our constant efforts for improvement, such as gaining a better idea of customer needs and improving quality and production environments. It has been fully and widely used across the entire range of Negurosu products as a system of manufacturing guidelines that allows us to improve our quality assurance capabilities and satisfy customers more than ever. The ISO 9000 series constitute the quality assurance standards of the International Organization for Standardization（ISO）. The certification bodies, accredited by the Japan Accreditation Board for Conformity Assessment （JAB）, examine and screen the quality management systems of enterprises or manufacturers （structures or arrangements for quality control） from the standpoint of a third party, to determine whether or not they comply with the ISO requirements, and whether or not they actually manufacture their products in accordance with their quality management systems.
