Pylon barrier (fire-resistant coating material) / stair slit (special slit)

This is an introduction page for the pylon barrier (non-expanding fireproof coating material for steel beam penetration holes) and stair slits (special slits).

**Pylon Barrier** The pylon barrier is a fire-resistant covering material for steel beam penetration holes, and it is a reliable non-expanding product. It is 12mm thick and has obtained Minister of Land, Infrastructure, Transport and Tourism certification for 1, 2, and 3-hour fire resistance. By considering its adoption from the design stage, it is possible to reduce beam depth, secure ceiling height, and create a more spacious appearance. **Benefits** ■ Increased effective area of penetration holes ■ Reduction in reinforcement costs for penetration holes ■ Possible reduction of beam depth ■ Usable even if the penetration hole diameter exceeds 1/2 of the beam depth (specific ring reinforcement method) *Please be sure to check the certification conditions before considering.* **Stair Slit** As the necessity for structural design concerning seismic slits increases, designs incorporating slits in stairwells are becoming more common. Amidst the diversification of building designs, our company is capable of producing various special slits, including those for stairs. (In addition to stair sections, vertical slits for knee walls, curtain walls, and beams can also be produced.)
