MGO Board Features

Fire Resistance

WT's magnesium oxide board, subjected to rigorous testing following ASTM standards, showcases an impressive A1 fire rating.

Water Resistance

MGO panels demonstrate exceptional resistance to deformation, swelling, or delamination upon brief exposure to moisture. While they retain resilience under such circumstances, prolonged exposure is ill-advised.


Eminent for superior strength, durability, and a lightweight structure, WT's magnesium oxide panels surpass competitors. Their refined finish conceals unparalleled screw and nail retention capabilities, facilitating effortless scratching and cutting.


Fashioned from MGO material, WT's magnesium oxide board circumvents the generation of fly ash, formaldehyde, crystalline silica, or hazardous substances in any setting, ensuring a secure and salubrious environment.

Weather Resistance

Magnesium oxide crystals (MGO) forge robust bonds between magnesium and oxygen atoms, enabling enduring utilization in any atmospheric condition. WT's magnesium oxide panels are tailored for sustained performance in varied weather settings.

Environmental Friendliness

WT's magnesium board is manufactured through a low-energy production process, bolstering environmental sustainability. Moreover, it is entirely recyclable, aligning with our dedication to eco-conscious methodologies.
