         5 . The drop ceiling according to  claim 1  wherein the circular support frame is coupled between adjacent straight frame members. 
     
     
         6 . The drop ceiling according to  claim 1  wherein the circular support frame is supported using support wires. 
     
     
         7 . The drop ceiling according to  claim 1  wherein the circular support frame is coupled to the T-shaped frame members using a flange in slot coupling mechanism. 
     
     
         8 . The drop ceiling according to  claim 1  further comprising a cover disposed within the circular support frame. 
     
     
         9 . The drop ceiling of  claim 1  wherein the T-frame member is formed from a single sheet metal strip. 
     
     
         10 . The drop ceiling according to  claim 1  further comprising a component at least partially disposed through the circular support frame the component selected from the group consisting of a light, a sensor, sprinkler head, a smoke detector, a camera. 
     
     
         11 .  Claim 10  where in the component is fixably coupled to the circular support frame. 
     
     
         12 . A drop ceiling frame construction comprising:
 a first T-shaped suspended frame member;   a second T-shaped suspended frame member coupled to the first T-shaped frame member at a 90 degree angle;   a curved support frame coupled to both the first and second T-shaped suspended frame members; and   a ceiling tile defining a first straight edge engaged with the first T-shaped frame members and a curved surface coupled to the curved support frame.   
     
     
         13 . The drop ceiling according to  claim 12  where in the ceiling tile defines a second straight edge engaged with the second T-shaped support frame. The drop ceiling according to  claim 12  wherein the curved support frame has an L-shaped cross-section. The drop ceiling according to  claim 12  wherein the curved support frame a curved support frame has a first coupling flange defined at a first end configured to engage the first T-shaped suspended frame member, and a second coupling flange configured to engage the second T-shaped suspension frame member. 
     
     
         16 . The drop ceiling according to claim  15  wherein the first T-shaped support frame defines a coupling slot and the first coupling flange is disposed within the coupling slot. 
     
     
         17 . The drop ceiling according to  claim 16  wherein the second T-shaped support frame has a support surface and wherein the second coupling flange engages the support surface. 
     
     
         18 . A drop ceiling frame construction comprising:
 a curved support frame member having a radially disposed curved tile support flange and a body member defining a plurality of coupling slots;   a first plurality of T-shaped frame members;   a second plurality of T-shaped frame members each having a coupling flange coupled to one of the plurality of coupling slots, wherein said first and second plurality of T-shaped frame members defining a grid pattern.   
     
     
         19 . The drop ceiling frame construction according to  claim 18  wherein the curved support frame member is a circular member having a radially disposed support tile support flange 
     
     
         20 . The drop ceiling frame construction according to  claim 18  comprising a ceiling tile having a first straight edge coupled to one of the second T-shaped frame members, said ceiling tile defining a second curved surface engaged to the radially disposed curved tile support flange, and a component at least partially disposed through the circular support frame the component selected from the group consisting of a light, a sensor, sprinkler head, a smoke detector, a camera.
