Application scenarios
Pultruded grating T-3320 is suitable for industrial platforms, walkways, trench covers and equipment operating surfaces where load-bearing and corrosion resistance are required. If your operating conditions involve specific media, temperatures or load conditions, please contact us to discuss your specific service environment.
Selection guidance
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 inform us of your service environment and load-bearing requirements, and we will help you confirm a suitable configuration.
Product advantages
Pultruded grating uses pultruded profiles as load bars, offering high longitudinal strength and stiffness, light weight, corrosion resistance, ease of cutting and installation, and reduced maintenance requirements. Compared with traditional metal grating, it is more adaptable in corrosive environments such as humid, acid and alkaline conditions.
