Moreover, FRP ducts are lightweight, which significantly reduces the installation time and labor costs. Their light weight also lessens the load on building structures, making them suitable for high-rise buildings and other large-scale projects. In addition, the non-conductive nature of FRP minimizes the risk of electrical hazards, enhancing workplace safety In addition, the non-conductive nature of FRP minimizes the risk of electrical hazards, enhancing workplace safety In addition, the non-conductive nature of FRP minimizes the risk of electrical hazards, enhancing workplace safety In addition, the non-conductive nature of FRP minimizes the risk of electrical hazards, enhancing workplace safetyfrp ductwork.
