Acoustic technology light steel floor joists between the inner walls and filling the glass wool Steel plant cost, effectively prevent the spread of the audio portion through the air, and for the impact of sound propagation through the solid steel plant, construction process as follows: For household wall constituting two wall studs with two channels with a channel wall intermediate space; and for fixing plasterboard ceiling with small keel with an elastic structure with a small notch to effectively reduce solid sound propagation between floors . High-strength steels Steel should significantly improve its yield point strength; in addition to new varieties rolled steel, such as H-beam (also known as wide-flange beam) and the T-shaped steel and profiled steel plate to accommodate large-span structures and high-rise building needs.
