Calcium silicate board products are made of SIO2 and CaO through through mixing, heating, gelling, molding, autoclaving and drying processes, adding environmental protection fiber. It is new energy-saving heat insulation material without asbestos, which can be long-term used in 650°-1050° high temperature environment.

1. The board materials must be put on the wood pallet/bracket in horizontal placement.
2. It is not allow to put the board materials at the place of fixed position.
3. Make a measure to prevent rain and snow weather if the board materials in outdoor circumstance.
4. Make sure to keep the board materials untouched the water or liquid substance directly at any time.
5. Lift up the two end of the board materials in carefully when carry them, keep the oblique angle of the board materials when move them.
6. Single people to carry and operate the board materials is prohibited, deformation handling of the board materials is not allowed too.
