Application Scenarios
Pultruded Grating I-4015 is assembled from pultruded "I"-shaped load-bearing bars with solid tubes or rods as connecting rods. It is suitable for platforms, walkways, trench covers and various industrial operating surfaces where load-bearing capacity and corrosion resistance are required. In chemical, water treatment, electroplating, marine and general corrosive media environments, different resin systems can be selected according to specific working conditions. Please contact us to describe your operating environment so we can confirm a suitable solution.
Selection Guide
When selecting, we recommend first clarifying the medium type and concentration, ambient temperature, load form and installation support span, then choosing the resin type (such as phenolic, vinyl ester, etc.) as well as grating thickness and load-bearing bar spacing accordingly. Different resins have different emphases in flame retardancy and corrosion resistance. Please contact us for specific specifications and load-bearing data.
Product Advantages
Pultruded grating uses continuously pultruded profiles as load-bearing units. It features light weight and high strength, corrosion resistance, non-conductivity and maintenance-free operation, is easy to cut and install on site, and can reduce later maintenance costs. Its surface can be made anti-slip to improve walking safety. For specific performance details, please contact us for more information.
