Request a Quote
Duowei’s fireproof mineral wool sandwich panel uses two-layer high quality colored steel sheet or other precision profiled metal plate as the panel board. After the board is rolled and shaped, stripped rock wool is turned 90° (making its fiber perpendicular to upper and lower steel sheets). The shaped board has excellent fire prevention properties as well as thermal insulation. These are amazing choices for industrial building enclosure system.
