- Without problems of detachment of the plaster from metal profiles
- Without problems of loosening of the springs and then the cover
- Resistant to shock and falls because made in plaster fiber
- Simple, effective, practical and economic
- Without finishing problems because the painting roller covers any difference of surfaces and from that of the plasterboard.
