Cold Zinc Sheets – Heat Resistant Panels
Roofing and wall panels are both cold (heat resistant) zinc sheets making the factory be always cooler than other factories with colored zinc panels despite having insulation layer. A few of people has paid attention to this issue of making by a cold zinc panels, if the colorized zinc panels are covered on the factories, the factories are heated then the insulation layer must be applied. However, the insulation layer will be ruined and fallen off after the first few years of use, this makes the thermal efficiency of the insulation no longer available, causing loss of aesthetics for the whole. If the factory is fired, the insulation layer is burned and hitting over workers and fire-fighters.
