Application Scenarios
Pultruded grating I-4010 is suitable for platforms, walkways, trench covers and stair treads that require both load-bearing capacity and corrosion resistance, and is commonly used in chemical, water treatment, power and marine engineering environments. Different resin systems correspond to different media and temperature conditions; please contact us to confirm the specific applicability based on your operating conditions.
Selection Guide
When selecting, first clarify the load-bearing requirements, span, corrosive media and flame retardant requirements, and then choose the resin type as well as the grating thickness and mesh size accordingly. In the table, systems such as OFR, IFR, VEFR and phenolic each have their own emphasis in flame retardancy and corrosion resistance. Please contact us for detailed specifications and selection advice.
Product Advantages
Pultruded grating is assembled with pultruded I-shaped and T-shaped profiles as load-bearing bars and solid tubes or rods as connecting rods, so it has strong longitudinal load-bearing capacity and high stiffness, and is lightweight, corrosion-resistant and easy to cut and install. Its surface is anti-slip and requires low maintenance, making it suitable as a replacement for metal grating.
