GRP (Glass Reinforced Polymer) gratings are widely used across various sectors due to their robust construction and resistance to corrosive environments. Sumip Composites manufactures these gratings by blending fiberglass with resins, which provides strength and protection against challenging conditions.

From a technical standpoint, GRP gratings offer a favourable strength-to-weight balance, making them simpler to install compared to traditional metal options. They come in a range of thicknesses, typically from 25 mm to 50 mm, depending on specific load-bearing needs. GRP gratings can be produced in both molded and pultruded forms—molded gratings provide flexibility and are used in settings requiring resilience, whereas pultruded versions are better suited for longer spans and higher loads.

The surface of GRP gratings is non-conductive and slip-resistant, which makes them ideal for areas where electrical insulation and worker safety are critical. Industries such as chemical processing, oil and gas, water treatment, and marine operations commonly utilize these gratings. Additionally, GRP gratings resist chemical exposure, withstanding substances like acids and solvents without degrading.

The open structure of these gratings ensures efficient drainage, which minimizes liquid accumulation in areas like walkways, platforms, and trench covers. Depending on design specifications, they can support loads from 500 kg/m² to 2,000 kg/m², making them adaptable for a variety of industrial applications.
