We produce high-quality products with a universal rolling mill that consists of horizontal rolls and vertical rolls, based on rolling technology nurtured over many years of experience. It is an indispensable product for structural materials for construction and civil engineering, and components for machines and vehicles.
In addition to being used as a construction material, it is also widely used as a component of various machines such as steel towers, ships, industrial machinery, and railway vehicles.
Due to its excellent sectional efficiency, it is mainly used as a member of ships and offshore structures. In addition, it is also used for construction materials and mechanical structures such as vehicles. Also, our flat steel bars and R-flat steel are used by a wide range of customers, including shipbuilding, construction, bridges, and construction machinery.
We are able to manufacture ultra-large construction flat steel that are unrivaled by other companies. Our flat steel (U515×115) is used at the entrance of the National Art Center, in Roppongi Tokyo.
We produce products with various special shapes. Based on our unique deformed section steel technology, we will continue to actively develop and manufacture new products to meet the various needs of our customers.
It is a component of all kinds of wheels according to the purpose, such as passenger cars, large trucks and buses, and construction vehicles.
Super Giant Off the Road Rim components for dump trucks used at large-scale ore mining sites overseas. With a rim diameter of 63 inches (approximately 1.6m) and a weight of 2.8 tons, it is the world's largest wheel.
The iron belt of a construction vehicle is track, and the parts that make up the belt that come into contact with the ground are called track shoe. It prevents the vehicle body from sinking in wetlands and rough roads, ensuring high running performance.
cutting edge materials supported by superior heat treatment technologies are highly rated for their full performance under all working conditions. Our unique material design technology, which considers wear resistance, toughness, strength, etc., is utilized.
section steel used for the vertical part (mast) of the front of a forklift. It is a product that requires high strength as well as wear resistance and weldability.
We manufacture segmented materials used in the shield tunneling method *, a tunnel excavation method. Our segmented materials are used in tunnels such as the Shinjuku Line of the Central Circular Route of the Shuto Expressway system and the Tokyo Outer Circular Route.
*Shield tunneling: A type of construction method for digging tunnels underground. It is considered a highly reliable method that can stably build safe, high-quality tunnels while minimizing the impact on the surface environment, and can be used in urban areas and on soft ground.
These are HSST (normally conducting magnetically levitated linear motor car) rails. They were used on the HSST "Linimo" linear motor car that ran at the EXPO 2005 AICHI, JAPAN, and are still in use today.
Z-steel is section steel with a Z-shaped cross section that is used for railway vehicles after butt-welding the long sides.
