Frame dragging is a theory which says that space is elastic, and particles in it will exchange energy with it. In the scientific world, elastic means that when you apply a certain amount of force to an object (which will cause it to bend) and then remove the force, the object will return to its original shape and energy state.
METAL BAR GRATINGS. Embed frames cast into concrete floors and substructures serve a multitude of purposes that extend the effective life of your completed construction project. Frames form a rigid shield for concrete lead edges and perimeters which are subject to cracking and chipping when left unprotected. During construction, these rigid (1/4 minimum thickness) frames expedite forming and provide a welded structure that assures accuracy in the concrete pour.
