The industry's only in-house "M-Grade Certified Factory"

There are three steel frame fabrication plants: the headquarters plant (Taku City, Saga Prefecture), the second plant (Taku City, Saga Prefecture), and the Kita-Kanto plant (Kita-Ibaraki City, Ibaraki Prefecture). The steel frame fabrication plant at the headquarters of Yamaguchi Sangyo, based in Taku City, Saga Prefecture, acquired "M Grade" certification in December 2018. The certification enables the company to handle large-scale projects and public projects designated by the certified factory. Inheriting the skills of skilled workers cultivated over the 50 years since its establishment, the company has further improved quality and productivity by introducing the latest equipment and other measures. As a result, we have received high evaluations for our contribution to cost reductions and shorter construction periods, and we have been involved in large-scale projects and public projects. We will continue to provide even higher quality products in the future.

What is M-Grade?

The purpose of the Steel Frame Fabrication Factory Certification System is to certify to the client that the steel frame fabrication factory possesses the quality control capability and technical skills necessary to produce and supply architectural steel frames of appropriate quality. Under the factory accreditation system, the reliability of the quality assurance of architectural steel frames (especially welds) produced at steel fabrication factories is evaluated, and based on the evaluation results, the Minister of Land, Infrastructure, Transport and Tourism grants accreditation. The quality of steel frames is ensured by the effective functioning of quality control capabilities and technical skills involved in steel frame fabrication. For this reason, the following points are strictly examined and evaluated in factory accreditation.
