Polished White Roof Fire Insulation Board

  • Fire Fighting Air Duct

  • WT


Introducing our revolutionary fireproof board made of steel-faced magnesium - the ultimate solution for safeguarding against fire and corrosion. Our product showcases a one-of-a-kind windpipe core comprised of inorganic substances like magnesium sulfate and magnesium oxide, as well as polystyrene particles and perlite. This unique blend results in an exceptionally sturdy and fire-resistant material that is shielded by an attractive steel coating.

Our steel-faced magnesium composite windpipe not only offers outstanding fire resistance and impressive strength, but it is also lightweight and visually appealing. With its extended lifespan and the added advantage of galvanized angle steel flanges and I-shaped connecting strips, this insulated windpipe, resistant to fire, is the finest choice for smoke exhaust systems.

Invest in our steel-faced magnesium fireproof board and experience the peace of mind that accompanies the knowledge that your structure is shielded from the perils of fire and corrosion.
