Application Scenarios
Pultruded Grating I-5015 is suitable for platforms, walkways, trench covers and equipment operating surfaces with combined requirements for load bearing, corrosion resistance and ventilation/drainage. It is commonly used in corrosive environments such as chemical, water treatment, power and marine engineering. Specific scenario suitability must be evaluated based on load, span and media conditions. Contact us for targeted recommendations.
Selection Guide
When selecting, please confirm the resin system (such as orthophthalic, isophthalic, vinyl ester or phenolic), flame retardancy requirements, grating thickness and load bar spacing, and whether the cross rod type matches your span and load. We can recommend suitable specification combinations based on your operating conditions. Contact us for detailed specifications and quotations.
Product Advantages
With pultruded I-profiles as load bars and solid tubes or rods as cross rods, the product maintains light weight while offering good longitudinal load-bearing capacity and corrosion resistance, and is easy to cut, install and maintain. Anti-slip surface and color options can be configured on request. Contact us to confirm available options.
