Trench Covers, manufactured by Sumip Composites, are engineered to provide a corrosion-resistant and lightweight solution for covering trenches, cable ducts, and service channels. These covers are made from glass fibers and resin, resulting in superior durability in harsh environments such as chemical plants, water treatment facilities, and oil refineries.

Technically, GRP Trench Covers comply with EN 124 load classifications, available from Class A15 (for pedestrian use) to Class D400 (for areas with heavy vehicular traffic). Their load-bearing capacities range from 500 kg/m² to 2,000 kg/m², depending on design specifications. Despite being lightweight, GRP covers maintain structural integrity under high loads, eliminating the need for heavy machinery during installation.

GRP Trench Covers are non-conductive, making them ideal for use in electrical installations and reducing the risk of electrical hazards. They also feature a non-slip surface, ensuring safety in wet or oily conditions. These covers offer resistance to a wide range of chemicals, including oils, solvents, and corrosive substances, ensuring longevity and low maintenance in industrial environments.

Available in widths from 200 mm to 1,000 mm, GRP trench covers can be customized with locking mechanisms for added security. The material also withstands extreme temperatures, ensuring performance in fluctuating conditions without cracking or warping.

Overall, GRP Trench Covers provide a cost-effective and durable alternative to traditional materials like steel or concrete, with a longer service life and reduced maintenance costs.
