Yaoyi Warehouse
Ningbo Yaoyi Stainless Steel Co. Ltd. was founded in 1996. Yaoyi covers an area of 50 acres, and near the Ningbo airport. Over the years, the company mainly produce and sell different kinds of stainless steel coils ,tubes and sheets. It also independently developed one kind of high tensile non-magnetic stainless steel-Y1 and one kind of hard magnetic stainless steel-Y6. Also, other products like SUS 201, 202, 301, 301Ni7, 304 and 316 and so on.
Yaoyi keeps the industry-leading quality for years. Because it had technological improvement on cold rolling mill and the heat treating process. Yaoyi is good at producing high hardness and high-tensile coils. Also, we specialize in customized material for different clients.
Our strength is the relationships with our customers, suppliers, and employees. Moreover, the quality management system (REGISTERED TO ISO 9001:2008) ensures our quality and the service.
