Standard
Being the leading enterprise of calcium silicate/fiber cement board,all Dongshang products are 100% non-asbestos,brucite,meerschaum,inorganic fibre or formaldehyde.All Dongshang board are in compliance with national standard JC/T564.1-2008 . And we carry out the standard of ISO-9001:2008.Our boards also according to and GB 6566-2001 by worldwide accredited laboratories. Meanwhile, DongShang obtains the China Environmental Labeling Product Certificate and fire safety test report . Our product satisfy the national environmental prescript from its raw material to the end of the product which including the manufacturing, processing and usage.
fiber cement Board have:
1. Excellent for fire resistance
Good for fireproof, if a fire, the Board will not burn, and does not generate toxic fumes.
2. Excellent water resistance
Has excellent water resistance, in the toilet, bathroom, high humidity areas, can maintain the performance of consistent expransion or transformation.
3. High strength
High strength, 6mm plate strength far exceeds the normal 9.5mm thickness of the gypsum board. Calcium silicate Board walls sturdy, to be easily damaged rupture.
4. Dimensional stability
Adopts advanced formula, and then under strict quality control, production of wet rose and drying shrinkage control in the most ideal range.
5. Sound
Has good thermal insulation performance, 10mm thick wall of thermal insulation performance significantly better than ordinary brick wall effect, both good noise.
6. Durability, and long service life
Stable performance, corrosion resistant to acid-base, not, or no tidal or pest and Ant, and other damage, can guarantee that there are very long service life.
