Installation and accessories
Application scenarios
Pultruded grating I-5015 is suitable for platforms, walkways, trench covers and equipment operating surfaces that require a combination of load bearing, corrosion resistance and ventilation/drainage, and is commonly used in corrosive environments such as chemical, water treatment, power and marine engineering. Specific application suitability should be assessed against load, span and media conditions; contact us for tailored recommendations.
Selection guide
When selecting, please confirm in particular the resin system (such as orthophthalic, isophthalic, vinyl ester or phenolic) and flame retardancy requirements, the grating thickness and bearing bar spacing, and whether the connecting 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 bearing bars and solid tubes or rods as connecting rods, the product offers good longitudinal load-bearing capacity and corrosion resistance while remaining lightweight, and is easy to cut, install and maintain. Anti-slip surface, color and other options can be configured as needed; contact us to confirm available options.
Inquiry guidance
For detailed specifications of I-5015, resin selection, custom sizes and commercial terms, contact us for detailed specifications and quotations; we will provide selection advice and technical support based on your operating conditions.
Custom Cutting
Need panels that fit, or cut to shape? We custom cut FRP grating and profiles to your drawing: panels cut to size or to shape (corner cuts, cutouts), cut edges sealed with resin, and pre-cut and pre-drilled to drawing before shipping. See the custom cutting services.
