The roof of the steel structure is made of polyurethane roofing insulation board. The polyurethane roof energy saving board is suitable for the roofing inclination of 3% to the class of industrial and commercial buildings, self-cleaning high-grade panel, reducing the amount of ash on the roof, so that the building roof to maintain long-term crystallization, The crest has improved the bearing capacity of the roof panel, with large span, fast row, easy installation and so on. The lap is designed with fluid mechanics to ensure fast installation, air tightness and good effect.
General use of polyurethane insulation board, commonly used thickness o is 50mm, 75mm, 100mm, density 40kg / m3. Installation can generally reduce the indoor temperature 8-12 ℃, the construction process is convenient and quick, life up to 35 years. Because some of the steel plant plant heat and water vapor, these hot air and water vapor if not discharged in time, will accumulate in the plant, so that the steel plant temperature rise affect the steel structure plant environment. The solution to these problems is to ensure that the plant reasonable ventilation, the installation of appropriate appropriate ventilation system. Fair exhaust system installation will significantly improve the steel structure of the plant air environment, a larger reduction in steel plant temperature.
