| 屋面变形缝RTM的优点：采用滑杆确保变形缝装置变位时仍能保持中心及原有位置。 |
| 1、适应屋顶多方变化(Adapt roof displacement ) |
| 2、优良的防水性能抗御恶劣风雨气候 (Excellent，waterproof、weathertight system ) |
| 3、50%位移量 盖板自定中心，接合平整，华丽，美观大方(Minimum 50% movement) |
屋面变形缝RTM铝合金基座因定在屋顶上，基座上嵌有止水胶条(The continious moisture seal is embed in the continuous extruede aluminum frame which is fixed on the roof edge ) |
