System introduction:
Polyurethane Sandwich Roof Panel products adopt internationally most advanced six-component online automatic cooperation mixed pouring technology in raw material proportioning and process output, through which six-component continuous foaming is realized for the first time in China, and mixing and proportioning process can be realized online at a time; Moreover, formula can be adjusted according to the environment change to make raw material mixing more even and foam smoother by cooperating with aerating and mixing device, thereby producing high strength, energy-saving and environmental protection building boards.

POILISOCYANURATE, abbreviated as PIR; Composite boards developed by DG use excessive sulfone isocyanurate, so ring structure of chemical compound and higher sulfone isocyanurate index form the dense PIR, thereby making interior rigid foam more stable and have high heat resistance and flame resistance. Experiment shows that the bubble can endure 200 celsius in a short time and can endure 160 celsius in a long time.

Board type:

System composition:
Upper profiled sheet, polyurethane thermal insulation material, and lower profiled sheet

Connection way:
Polyurethane roof board is to be connected onto the purline with tapping screws and to be connected with the other board through lapping (the upper laps with the lower).

Product features:
DG polyurethane roof board uses concealed nail for connection and boards are lapped together tightly.
Unique waterproof groove design, effectively preventing rainwater leakage and avoiding cold bridge phenomenon
40mm corrugation height, greatly improving bearing capacity of roof board and also effectively lowering customer construction cost while ensuring building thermal insulation effect; Minimum roof slope can reach 3%

Scope of application:
No-bearing roof enclosure of various industrial workshops, civil buildings, public buildings and steel structure buildings
