Physical Specifications:


MgO board (MgSO4) is a sustainable, non-flammable building solution for residential and commercial applications. It delivers robust fire resistance of 2 to 3 hours, maintaining structural integrity at 800°C and resisting ignition until temperatures reach 1200°C.

MgO board retains stable structural integrity under humid conditions and minor bending stress. It effectively prevents common defects including warping, swelling and delamination for long-term consistent performance.

MgO board features a clean, non-toxic composition free of fly ash, formaldehyde and crystalline silica. Without harmful chemical additives, it ensures safe and healthy indoor and outdoor construction usage.


MgO board possesses inherent resistance to moisture, mold and pest infestation. It effectively avoids structural deformation and material deterioration caused by termites, extending building durability and service life.

MgO board is manufactured from natural mineral compounds with recyclable and landfill-safe properties. Validated by 36-month freeze-thaw testing, it supports stable and reliable all-season construction projects.

MgO decorative board exhibits excellent antimicrobial properties against mold, mildew and structural rot. Its chloride-free formulation eliminates micro-corrosion and material expansion risks in long-term service.
MgO decorative panels are ultra-durable, Class A fire-resistant, and moisture-proof surfacing boards built for high-end interior finishing applications. They’re a top choice for wall treatments in both commercial and residential spaces.
