FRP pultruded profiles are a new type of composite material made from glass fiber reinforcement as the raw material, resin as the binder, and glass fiber cloth as the covering reinforcement layer; after full impregnation, the material is heated, formed, and cured in a metal mold and then drawn by a pulling machine. With good physical properties, they are widely used in high-strength and long-span applications.

Applications:
Greenlogy TEC pultruded FRP profiles (manufactured by Greenlogy TEC) are widely used in many fields, combining corrosion resistance, high strength, dimensional stability and light weight with thermal insulation and electrical insulation properties. Durable Greenlogy TEC profiles provide years of low-maintenance service in areas where steel, aluminum or wood components are traditionally specified. Today these profiles are commonly used in highly corrosive applications that previously required stainless steel and other costly components.

Applications
Hook plates (isophthalic) are commonly used for edge fixing on platforms in chemical, electroplating and wastewater treatment applications, connecting to grating, handrails or profiles to provide reliable support and fastening. In applications requiring high strength and corrosion resistance, such as marine engineering and oil platforms, they also offer performance advantages. Actual suitability should be assessed against specific operating conditions; contact us for application guidance.
Selection guide
When selecting, determine the hook plate dimensions (A*B*T), angle (e.g. 75° or beveled edge) and installation method to ensure compatibility with the existing structure. Isophthalic resin gives the product better corrosion resistance than orthophthalic resin, making it suitable for more demanding chemical environments. For detailed specifications and selection support, please contact us for professional advice.
Product advantages
Made with isophthalic resin, hook plates offer excellent corrosion resistance and mechanical strength, are lightweight, easy to install, and are insulating and non-magnetic. Glass fiber reinforcement ensures long-term durability, suitable for high-load and outdoor environments. We can provide customized solutions to meet your requirements; please contact us.

Operating environment
- Suitable for a wide range of indoor and outdoor environments; the glass fiber reinforced isophthalic resin system keeps hook plate performance stable in humid, salt-fog and general chemical corrosive atmospheres.
- Can be used long-term from ambient to moderate temperatures for platforms, walkways and structural support applications with heat resistance requirements; ambient temperature fluctuations have little effect on the dimensional stability of the profiles.
- Good resistance to acids, alkalis, salts and industrial atmospheres, suitable for hook plate connections and fixing in corrosive environments such as chemical plants, wastewater treatment and marine platforms.
- Under outdoor conditions with UV exposure, use with surface protection measures is recommended to extend the service life of the hook plates and their connecting structures.
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.
