[New Catalog] The latest version of the high-performance fire-resistant coating material "Pylon Barrier" for steel beam penetration holes. (2025.3.28)
The catalog for the Pylon Barrier has been updated. (With some certifications, high furnace cement has been added to the types of cement for sprayed rock wool.) The Pylon Barrier is a non-expanding product that has obtained Minister of Land, Infrastructure, Transport and Tourism certification for 1, 2, and 3-hour fire resistance at a thickness of 12mm. By considering its adoption from the design stage, it is possible to secure ceiling height and create a more spacious appearance. Benefits: ■ Increased effective area of penetration holes ■ Reduced costs for reinforcing penetration holes ■ Possible reduction of beam depth ■ Usable even if the diameter of the penetration hole exceeds 1/2 of the beam depth (specific ring reinforcement methods) *Since the Pylon Barrier is a ministerial certified product, there are certification conditions for its use. Special attention is needed regarding steel frame sizes (especially flange thickness), so this catalog includes a flowchart. Please check whether you meet the certification conditions. *Related data excerpts for fire resistance verification are also included. If you have any questions or concerns, please feel free to contact us.
