Magnesium Exterior Wall Board

A leading brand High strength 3-50mm thick One of the best magnesium board Premium MgO boards for various decorative purposes

Magnesium board,as magnesium exterior wall board,has features as follows:

(1)Non-flammability: Gemtreeboard is non-flammable and conforms to the national grade A1 standard (GB8624-2006 Grade A1). In case of fire, the board will not burn and not give off poisonous smoke, and is ideal in multi storey building such as offices and appartments for escape routes and shaftwall, or dividing walls in commercial units.(2)Water-proofing and moisture-proofing: The product is allowed to long-term expose to moist environment. Test results prove that after this material has been immersed in water for one month,it keeps its original shape without deformation or expansion and its dry-wet deforming ratio is 0%.(3)Problem-free: Gemtree board provides good insulation against bugs, fungus and corrosion. It can last for a long-time and will not corrode. (4)High-Strength and Lightweight: Owing to the density is not high ,the board is light weight, in this case, it can decrease weight of building greatly. At the same time, the material is high-strength and not easy to be damaged.

(5)Easiness to construct: Gemtreeboard is easy to cut, saw nail, stick. Gemtreeboard has a smooth finish one side that can be taped and jointed ready for decoration including wallpapering, painting, texture coat and veneer,  and a rougher side for tiling.

(6)Environment: Gemtreeboard does not contain any organic solvents, formaldehyde, asbestos, oils or other toxic substitances that can have a negative impact on the environment and waterways. As such, saw dust from Gemtreeboard can safely be disposed off in landfills. Off-cuts of Gemtreeboard can be reground and reused back at the production factory.

  

(7)Polywood substitution, particle board substitution and MDF substitution.
