Materials that Pan Komerc® use in the production of profiled sheet metal are made by world largest steel manufacturer Arcelor-Mittal®. Pan Komerc® is commited to specify raw material origin and establish longterm cooperation with selected suppliers in order to provide continious and verified product quality. Periodical supplier changes make product quality inconsistent and uncertain
All sheet metals used in our production have attests for physical and chemical properties. Roofing and wall profiles are certified on Belgrade Construction Faculty for load bearing capacities and quality Pre-painted galvanized sheet metal has 140 gr/m2 zinc coating, 7 microns of primer paint and 25 microns of weather resistant polyester paint over the steel base.
Legal guarantee provided by sheet metal suppliers is from 5 to 10 years which is valid under strict conditions. With over 35 years of experience in sheet metal, we can confirm that in most cases lifetime of sheet metal exceedes 25 years in moderate climate regions. Factors that have strong impact on sheet metal durability are local climate conditions, activity that is being performed in and around the building, roof pitch, storage and installation procedures. Colour of metal roofing also has an impact on its durability as brighter colours have up to 10% longer lifespan than dark coloured metal roofs.
The fact is that metal roofs absorb heat more quickly than concrete tiles. Advantage of metal roof is that it cools down more quickly than concrete roof tiles which accumulate heat for longer period of time. Temperature of metal roof during summer days will depend on roof color where darker colors, which absorb sunlight, gain more heat than lighter colors which reflect sunlight. Installation of additional roof insulation layers is recommended, such as rock wool Condensation may occur on the underside of uninsulated metal roof due to temperature difference between inside and outside space. DR!PSTOP anti condensation felt is applied during the roll forming process to prevent this side effect.
Main advantages of metal roofs are greatest durability compared to all other roofing materials, wind, hail and earthquake resistance. Metal roof covering have up to 7 times less weight than traditional concrete roof tiles for the same area, they are quickly installed, require minimal roof construction and their color is durable and long lasting.
Condensation may occur on the underside of uninsulated metal roof due to temperature difference between inside and outside space. DR!PSTOP anti condensation felt is applied during the roll forming process to prevent this side effect.
It is known that heavy rain fall produces increased noise on metal roofing. For residential buildings, wooden construction and insulation layers completely neutralize this effect.
Metal roofing do not represent any aditional danger in case of a lightning strike. On the contrary, metal roof coverings can be used as a part of lightning-conductor system if the sheet meal used for roofing is at least 0.6 mm thick.
