Sales Pitch

Pole technology
Steel processing techniques
<Warm spinning technique>
The warm spinning technique is a process in which a steel pipe is heated and tapered using a processing roll to form a tapered pole.

<Slip joint>
A slip joint is a means to join steel tube columns that allows construction of columns in a narrow space. A slip joint provides friction connection. More specifically, the ends of the tubes to be joined are expanded or shrunken, and the upper tube is inserted into the lower tube. The upper tube is pushed down by its own weight or hammering to the specified joint length. A slip joint has a simple joint structure that does not use fastening parts such as bolts.
Techniques for fatigue durability
<Non-protruding cover>
The cover has a smart appearance with no protruding parts, unlike normal box covers, and is safe for pedestrians. The steel plate is folded on the inside of the column to reinforce the edge of the opening. Fatigue resistance is improved through the non-use of welding seams and the oval shape of the opening.

<U-shaped ribs>
The concentration of stress on the top of the U-shaped rib is significantly reduced thanks to the shape as compared with conventional triangle ribs. This improves fatigue durability to class B or C. The rib is very effective in locations with significant traffic vibration, such as expressways and bridges.
Surface finishing techniques
<Syanettsu>
Heat-shielding fluorine resin coating that uses infrared reflective paint. It prevents the surface temperature of the pole from rising, protecting the equipment inside the pole and reducing urban heat-island phenomenon.
<Corrosion-proof bottom coating>
150 μm thick coating that increases resistance to acid and alkali, such as ammonium produced by the decomposition of dog urine and salt solution, or calcium chloride for snow melting chemicals, providing sufficient corrosion-resistance effect.
