Is the screw in the calcium silicate plate spin reliable?
Its production of materials and processes determine its hardness is high but toughness is insufficient, that is usually said to be too brittle. So it is slightly better than the performance of gypsum board, but still only as a surface decoration materials and not as a bearing structure. Usually with most of the use of light steel keel or blockboard. In this case, the screw through the calcium silicate board into the light steel keel or blockboard in order to reliable fastening.
Unreliable.
Calcium silicate board is made of inorganic mineral fiber or cellulose fiber and other loose fibers as a reinforcing material, calcium-siliceous material as the main cementing material, by pulping, billet and high pressure steaming and other processes and made.
Decoration is so used it Harder than gypsum board, so should be no problem. Screw spacing 20-30Cm
