Key Property of Magnesium Oxide (MgO) Board: Lightweight yet High-Strength

Feb 28, 2026

Core Definition: Magnesium Oxide (MgO) board is a new type of fireproof board with inorganic cementitious material as the matrix. It unifies lightweight and high-strength properties, combining convenient construction with structural safety.

Key Points:

Lightweight: Much lower density than traditional stone and concrete panels, greatly reducing building weight, easy to transport, cut and install, effectively improving construction efficiency.

High Strength: Excellent bending, impact and compressive resistance; not easy to deform, crack or break, meeting structural requirements for partition walls, suspended ceilings, external wall linings, etc.

Application Value: In high-rise and prefabricated buildings, as well as old building renovations, it reduces structural load while ensuring long-term stability and durability of wall and surface systems.
