Steel Rolling and Processing
Tenma Sheet Metal Division
A steel processing manufacturer that meets every need with advanced technology, quality, and quick responsiveness
NKC has long been a trusted contributor to industry through its extensive experience and proven expertise in the field of steel rolling and processing.
With advanced technical capabilities and a made-to-order production system, we respond flexibly to a wide range of customer needs—covering size, application, delivery schedule, and lot volume.
Our technology enables the processing of a broad spectrum of materials, from ordinary steel to special steels, stainless steel, and titanium. We maintain precise control over workability and strength, and can also handle thicknesses, hardness levels, and high-tensile products that major steel manufacturers typically do not process.
NKC’s steel sheets are widely used in demanding applications such as bearing retainer materials for high-speed railway vehicles—where quality standards are among the strictest—as well as in various automotive components and a wide range of industrial parts, earning a high level of trust and recognition across industries.
Sheet Rolling
Through cold roll processing, we produce materials with excellent surface gloss and smoothness, meeting customer requirements for thickness and hardness that cannot be accommodated by major blast furnace manufacturers.
Coil Rolling
We achieve high-quality cold reverse coil rolling that enhances spheroidization rates and workability. Our integrated one-stop process—from pickling and rolling to annealing—enables us to handle small-lot orders and short delivery times with efficiency and precision.
