Application Scenarios
Pultruded grating I-4020 is commonly used for platforms, walkways, trench covers and various industrial operating surfaces that require both load-bearing capacity and corrosion resistance, and is especially suitable for wet, acid-alkali or washdown environments. If your project involves special media or load conditions, please contact us for detailed specifications and a quotation, and our technical team will help confirm suitability.
Selection Guide
During selection, you can consider factors such as load-bearing requirements, span, corrosion level of the service environment and fire protection requirements, and match them with differences in resin systems (such as OFR-25, IFR-25, VEFR-25) and connection methods. As specific parameters need to be calculated according to the project, please contact us for detailed specifications and a quotation, and we will provide targeted recommendations based on your working conditions.
Product Advantages
This product is assembled with pultruded I-profiles as load-bearing bars and solid tubes or rods as connecting rods. It combines light weight, high strength, corrosion resistance and ease of cutting and installation, with an anti-slip surface and low maintenance cost. For more complete performance descriptions and comparison data, please contact us for detailed specifications and a quotation.
