Can be used even with a penetration hole diameter exceeding 1/2 of the beam height.

[New Certification] Usable with a hole diameter exceeding 1/2 of the beam height! (High Ring/OS Ring)

The "Pylon Barrier" has obtained ministerial certification in conjunction with OS Ring (Okabe Co., Ltd.), following Hailing (Senkushia Co., Ltd.) this time. (2021.6.7) Until now, it could be used in combination with reinforcement rings from various manufacturers, but the previous certification only allowed for through-hole diameters of up to 1/2 of the beam height. Since reinforcement rings can create through-holes of up to 2/3, it was not usable in that regard. With this new certification, it can now be used for through-hole diameters exceeding 1/2 of the beam height. (Hailing → up to 2/3 of beam height, OS Ring → up to 63.13% of beam height) 【Features】 By combining a maximum through-hole diameter of 2/3 with the Pylon Barrier (12mm), it is now possible to achieve more than ever before... ■ Increased effective area for equipment piping ■ Reduced beam height (Note: Due to structural strength considerations, it may not be possible to create through-holes of up to 2/3 with Hailing and up to 63.13% with OS Ring.) *Please be sure to check the certification conditions. (When used at 1/2 of the beam height or less, the existing certification conditions may have a broader application range.) For more details, please download the PDF or contact us.
