"Serving society with the finest quality" has been the Chun Yu''s outstanding tradition for the last fifty years. From the time that raw materials enter the factory until the time the finished products are packaged and shipped, all steps are monitored by a comprehensive quality assurance system. Because Chun Yu knows that stable, superior quality is the best way to advertise one''s products and establish a good reputation, it has therefore not been lazy when it comes to establishing a comprehensive quality control system, performing careful design work, and purchasing precision testing instrumentation. Chun Yu has received ISO-9002 certification from the Bureau of Commodity Inspection & Quarantine and Germany''s RWTUV, and has been accredited by the American Association for Laboratory Accreditation. These are strong guarantees that customers will get the best possible quality. Chun Yu is well-known for the manufacturing of Fasteners in Taiwan. All the reputation comes from staffs, efforts & persist, and customers supporting. We would share our gorgeous achievement with our friends who love us around all of the world.
