Application:
Hollow sandwich panels are generally used as insulation partitions and have good thermal insulation effects. At the same time, the glass magnesium board has the effect of fire retarding. It is widely use in worshop, temporary office/buiding, gymansia, villa, mobile building, guard booth, wall & roof materials for steel building or structure.
Features:
1. Fire proof: 67minutes
2. Weather proof
3. High density
4. High temperature withstanding capacity more than 1000℃
