The differences between standard mgo boards and sanded mgo board primarily lie in surface treatment, thickness accuracy, density, application areas, and cost:

1. Surface Treatment

Standard MgO Board: The surface is naturally formed without further treatment, resulting in a smooth front finish and a rougher back finish.

Sanded MgO Board: The board undergoes sanding, resulting in a smooth and even surface. This finish is ideal for applications requiring a high degree of flatness and visual appeal. The sanded surface also better accommodates additional decorative layers, such as veneers, paint, or coatings. It can be single side sanded or double sides sanded. With single-side sanding, the front side is smooth like the standard board, while the back side is sanded.

  2. Standard board back finish: rough
  3. Sanded board back finish: sanded

2. Thickness Accuracy

Sanded mgo boards offer greater thickness accuracy, with uniformity improved through sanding, making them suitable for applications with strict assembly or thickness requirements.

3. Density and Strength

Standard Magnesium Oxide Board: Typically has a density around 1000 kg/m³.

Sanded Magnesium Oxide Board: Generally denser, around 1300 kg/m³, and uses heavier-weight fiberglass mesh. This increases the board’s strength, making it better suited for applications requiring higher durability.

4. Application Areas

Standard Magnesium Oxide Board: Often used for interior walls, flooring, or other structural components that do not require exposure or high surface flatness.

Sanded Magnesium Oxide Board: Commonly applied in furniture, door panels, and other areas with higher aesthetic or flatness requirements, or as a base layer for decorative materials, ensuring smoothness and an attractive finish.

5. Cost

Due to the additional sanding process and increased density, sanded mgo board tends to be slightly more expensive than standard magnesium oxide boards. However, their high accuracy and surface finish make them highly cost-effective for decorative or precise installations.

6. Summary

Standard mgo boards are ideal for general construction applications, while sanded mgo boards are better suited for high-precision and high-aesthetic requirements. Selection should depend on the project’s needs for accuracy and budget.
