Netsuren's "PC steel bars" have contributed to the high strength of concrete products for over half a century.
PC steel bars are high-strength steel bars used in prestressed concrete, which improves the properties of concrete that is weak in tension by applying compressive forces in advance, thereby significantly enhancing the strength of concrete structures. They are used to continuously compress the concrete at a high stress level of 80% of the yield point. Netsuren PC steel bars have been widely used for over half a century in various applications including foundation concrete piles, concrete poles for power transmission and communication, concrete sleepers for railways, sewer systems, and box culverts for utility trenches, as well as in bridges and buildings. 【Features】 - Manufactured under one of the best quality control systems in the country, they possess stable mechanical properties and relaxation characteristics. - The ends are processed with rolled threads, allowing for anchoring. - Unbonded PC steel bars with a special asphalt-based polymer coating on the surface are also available.

Company information
Netsuren successfully commercialized and industrialized IH (Induction Heating) technology for the first time in Japan in 1946 (Showa 21). This IH technology is a double eco (Ecological and Economical) technology that uses clean electricity as its heat source, making it environmentally friendly and non-polluting. As a pioneer in this field, Netsuren has developed highly original products in addition to contract heat treatment processing, based on the know-how accumulated since its founding and its high level of technical and development capabilities, bringing transformation and contribution to various industries. The fact that Netsuren exists today and can contribute to society, even in a small way, is thanks to your unwavering support and warm patronage. To enhance corporate value through harmony and coexistence with customers, business partners, shareholders, society, and employees, Netsuren aims to remain a company with a dignified presence in the future, returning to the founding principle of "Technology of Netsuren," and will continue to make unceasing efforts to be of greater service to society in the coming era.
