This paper describes TG steel-framed light roof board\'s characteristics,application scope,technological principle,the process,main points of operation,the properties and requirements of the main material,safety precautions,quality requirements and benefit analysis.

Light green roof was compared with ordinary roofing based on a measurement method, and from the viewpoint of temperature wave delay and attenuation, the thermal insulation characteristic of the light green roof was studied.

Amendments and analysis to the vertical cracks on the roof-board of large warehouse;

Except for steel modulus in the type selection design the function requirement of building, installation way, site conditions and the type of roof boarding should be synthetically considered to acquire optimal type.
