Concrete Grade slabs are subjected to a lot of internal and external pressures due to temperature with the maximum harm caused to the edge of the plates at joint location. If floor joints are faulty it will affect the horizontal and vertical movements of the floor which may lead to stress cracks as being exposed to heavy traffic movement and immense pressure.

Sinus-shaped armour joints allow smooth, jerk-free movement of forklifts over the construction joints and allow proper load transfer between floor slabs. It is because if it's special shape which is not straight like conventional it classic shaped joints. They not only help in proper load transfer between slabs but also ensure longevity of the floor.
