Netsuren "PC Steel Bar" (JIS G 3109)

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.

What do you do if it gets seized up? (Screw Reinforcement Book Vol. 32)

Introducing how to deal with a seized screw in a blog format!

No matter what measures are taken, it is difficult to completely prevent screw seizing, which is quite a troubling issue. So, what should be done when seizing occurs? "The most reliable method is to cut and destroy the seized bolt or nut," but actually cutting it can be quite challenging. It may depend on the screw size, but the task can take several tens of minutes and involves risks. Moreover, if other components are damaged in the process, it could be a serious problem. Therefore, this should be considered a last resort. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*
