          FM Certification

          The FM certification for the steel structure industry mainly certifies the wind uplift resistance of metal roofing systems. The entire roofing system's wind resistance capability is calculated using FM's practical and effective testing methods. Almost no incidents of FM-certified roofing systems being blown off have been recorded; in contrast, uncertified roofing systems are frequently damaged by typhoons each year, resulting in significant losses.

          product feature :
          OPEN's roofing system has passed five groups of FM tests, and the FM-certified RP-SSR roofing system can withstand wind uplift forces of up to 500Kg/㎡, five times stronger than uncertified panel types.
