Installation and accessories
Application Scenarios
Pultruded grating HL-5020 is suitable for industrial platforms, walkways, trench covers and equipment operating surfaces that require load-bearing capacity, corrosion resistance and slip resistance. Typical applications include chemical, water treatment, electroplating, marine engineering and other wet or corrosive environments, and it can also be used in structural parts requiring insulation or lightweight construction. Please contact us to confirm suitability for your specific application.
Selection Guide
When selecting, consider the load-bearing span, the corrosive media in the service environment, whether flame retardancy is required and the installation method, then match the appropriate resin type and grating thickness. Different resin systems have different strengths in corrosion resistance and flame retardancy; please contact us for detailed specifications and selection advice. We can recommend a suitable configuration based on your operating conditions.
Product Advantages
Pultruded grating is assembled from pultruded "I" and "T" profiles as load-bearing bars and solid tubes or rods as connecting rods. It is lightweight, high-strength, corrosion-resistant and not prone to rusting. Compared with traditional metal grating, it is free from electrochemical corrosion, has lower maintenance costs, and is easy to cut and install on site. Its overall structure is stable and suitable for long-term exposure to harsh environments.
Inquiry Prompt
