Summer studio in Yumi steel,All the people enjoyed one wonderful time,during the summer studio activity.Hope we can recover from hard working,from the short journey.
The roofing panel for photovoltaic system is made of high-quality brand steel sheets for the surface,and it's continuously cold-formed and profiled.This new heat-insulating and flame-retardant material is made of D-BASF material and it is a multifunctional roofing product integrating heat preservation,energy saving and solar energy utilization.The roof rib can be directly connected with the clamp,without penetrating the roof structure.It is suitable for industrial buildings with a roof inclination of 3%.The self-cleaning high-grade panel reduces the amount of dust on the roof and keeps the building roof for a long time.Self-cleaning performance provides a systematic solution for the use of roofing solar energy.
