Embedded Steel Plates in Prefabrycate Panels

A popular technique for connecting precaste concrete panels or structural insulated panels (SIP) to steel frames is to cast steel plates or brackets directly into the panel during facation. These plates have predrilled holes that align with connection point on thee steel structure. Once thee steed frame is erected, thee panels are cranne- lifted into position and bolt in place.
