Fire resistant encasement

ZC-1K The method of encasing structural steel columns (square shaped steel) providing up to 1 hour column fire protection
ZC-1 The method of encasing structural steel columns (H-shaped steel) providing up to 1 hour column fire protection
ZC-2 The method of encasing structural steel columns (H-shaped steel) providing up to 2 hour column fire protection
ZC-3 The method of encasing structural steel columns (H-shaped steel) providing up to 3 hour column fire protection

Yoshino Fire Resistant Column Encasement System ZC-1K, ZC-1, ZC-2, ZC-3
The fire resistant column encasement system incorporating the fire resistant gypsum board “Tiger Board Type Z”

[Recommended use location]
  • Structural columns in steel structure buildings (office buildings, hotels, housing complex, large-scale or small-scale shops, factories, warehouses)

[Features]
  • Simple structure:
    Made by attaching fire resistant gypsum board “Tiger Board Type Z” to steel framings with screws.
  • Excellent workability:
    The construction work for encasing columns and interior finish can be carried out by the same builders or constructors.
    Dry construction system - stable qualities, easy work, short term work
    Surface can be decorated with paint or wallpaper. - This leads to reduction of total cost.
  • Minimize effects on sound insulation performance:
    When using the system with sound insulation walls, effects on sound insulation performance can be minimized.
