(1) Value ability
The synthetic resin roof tile have biaxial properties above geometry even the temperature changes that will be balanced itself and guaranteed the size no changes that due to the thermal expansion as 4.93*10/-5℃
(2) Refractory
Synthetic resin roof tile made by the nonflammable pvc resin which have been tested as level B1.
(3) Insulations
The products is insulation material that will be safe when the accidental discharges happened.
(4) Anti-load capacity
There is no crack and damages under the load of 150 kgs.
(5) Anti-corrosion
The excellent corrosion resistant ,over a period of time soaked in the acid that no any chemical reaction.
