Quality Assurance

We promise to provide the highest level of reliability and safety by complying with internationally recognized quality assurance standards.

ISO9001 Certification

ISO9001 is the quality management standard provided by the International Organization for Standardization (ISO) for defining industrial standards. This certificate is crucial for supplying products not only to the United States and Europe but also all over the world.

We, at Daido Kogyo Co., Ltd., are qualified by the Japan Quality Assurance Organization (JQA) for every process from design, development, production, and installation to technical assistance services for all of the products we manufacture including conveyor systems, welfare equipment, rims and wheels as well as various kinds of chains.

API Standards Certification

The petroleum industry field is the core of today's industries. The United States industry, which leads the global market, defined very strict quality management regulations for all machinery components related to oil field development and petroleum refineries. API (American Petroleum Institute) is an institute responsible for qualifying in accordance with these regulations.

We, at Daido Kogyo Co., Ltd., obtained this certificate in 1972 and have delivered our D.I.D products to domestic customers, as well as the U.S. market, since this time.
