Application Scenarios
Pultruded Grating T-3320 is suitable for industrial platforms, walkways, trench covers and equipment operating surfaces where load-bearing capacity and corrosion resistance are required. If your working conditions involve specific media, temperature or load requirements, please contact us to discuss your specific operating environment.
Selection Guide
When selecting, factors such as resin type (e.g. orthophthalic, isophthalic, vinyl ester or phenolic), load bar specifications, grating thickness and mesh size, as well as installation support span, should be considered comprehensively. Please share your operating environment and load requirements with us, and we will assist you in confirming a suitable configuration.
Product Advantages
Pultruded grating uses pultruded profiles as load bars, offering high longitudinal strength and stiffness, light weight, corrosion resistance, easy cutting and installation, and reduced maintenance requirements. Compared with traditional metal grating, it is more adaptable in humid, acid and alkali corrosive environments.
