Frequently Asked Questions
Unlike galvanized steel, which eventually succumbs to salt-spray corrosion and rust, FRP is chemically inert. It does not oxidize, eliminating the need for recurring anti-corrosion treatments and extending the system life to over 30 years.
FRP is an electrical insulator, which means it does not conduct electricity. This significantly reduces the risk of electrical grounding issues and prevents electromagnetic interference (EMI) that can disrupt sensitive communication cables.
For standard load requirements, a spacing of 1.5 to 3.0 meters is typically recommended. However, for heavy-duty industrial cables, we advise reducing the spacing or using reinforced brackets to maintain structural integrity.
Yes, our FRP products are treated with specialized UV-resistant coatings. This prevents the polymer matrix from degrading under direct sunlight, ensuring that the mechanical strength remains intact over decades of exposure.
Our products are manufactured to meet rigorous global standards, including ASTM D5364 for FRP grating systems, NEMA VE-1 for cable tray performance, and ISO 14692 for applications in highly corrosive environments.
Maintenance is minimal compared to metal. We recommend quarterly visual inspections for debris accumulation or surface cracks and cleaning using non-abrasive agents to preserve the resin surface.
