Benefits to Customers

Not our regular size flat bar but a product with customer chose sizes will reduce both its weight and cost. ※For instance, you can order 2.5x15 instead of
  ordering 3.0x19 and reduce the thickness and width.

Slit coil is cold rolled its thickness and width through mold, so that cutting, punching, corner cutting, and bending processes are all operated on the same line. It's also available as a part.

We can provide both round and sharp edges. Our round edge surface is safe to touch. Please ask for any special shapes.

We are able to produce flat bar with maintaining property of its raw material. We currently produce parts for automobiles with using SAPH-440 for vehicles.

For slit flat bar, we mainly produce pickled steel that is suitable for pressing process due to its surface treatment, different from black surface, which has surface scale. The pickled steel is a good substitute for cold finished flat steel in terms of cost performance.
