We are a primary wholesaler, extensively selling various steel materials and specialized steel materials.
Upon our customer's requests, we also perform heat treatment, surface treatment and mechanical processing, in order to induce the properties of steel materials to the maximum limits.
Forged products whose production costs can be cheaper than cutting products.
Those products are dense in internal tissues and superior in mechanical strength, which are used in all kinds of fields from industrial machines to automobiles, ships and airplanes.
Depending on products, we propose the optimum production method, such as hot, warm or cold forging as well as free forging by skilled technicians and super large-scale forging.
Precision casting （Lost-wax） can manufacture products with much higher dimensional accuracy and smoother surface compared with conventional casting. In particular, it is suitable for products with complicated and thin shape which are difficult for mechanical processing. Moreover, this casting can contribute to cost reduction by unifying traditionally used multiple parts.
Minor metals are essential materials for present high-technology industries. We are engaged in providing minor metals for Japanese customers based on advanced researches and analysis in the global markets such as China.
We are offering quality products at low cost.
