Steel structure design of a certain degree of the status of the deployment of lighting panels or lighting glass, should consider the use of skylights and steel structure works in harmony with the construction of the roof and steel structure of the operation of the anti ionization. Reduced albedo for sound, backward indoor. Sound absorption performance of the steel structure in Changsha at the bottom of the laying of sound-absorbing cotton, and on the floor to complete the punching.

Steel house to prevent rain water from the inside of the steel structure of the roof. The key to the rain is through a joint or steel structure. To achieve the performance of prevention of seepage, in use after the screw mouth sealing gasket hidden flow, solve the sealant joint or riveted on the plate, it is best to use long board to eliminate all kinds of joints in the lap, abdominal distension careful prevention by ionization.

Sound from the room to the repression from the interior to the biography of indoor or outdoor. In Changsha steel structure engineering layer filled with thermal insulation material (usually by thermal insulation cotton as), thermal insulation effect of metal roof layer on both sides of the sound intensity difference. The density and thickness of heat insulation effect and heat insulation material. Attention should be paid: thermal insulation material on the opposite frequency of sound barrier effect is not the same.
