What material is the fiberglass trench cover made of? The fiberglass trench cover plate is made of high-purity resin material of meta benzene type, with a transparent and smooth texture. The made grille panel has high strength and is not easily discolored in external sunlight and atmospheric environments. Trench cover plate is the most widely used type of fiberglass cover plate, such as common trench cover plate, trench cover plate, sewer cover plate, and so on. Its performance is superior, with the characteristics of light weight and high strength, and it has high wear resistance. The surface of the cover plate will undergo certain anti slip and wear-resistant treatments.

The fiberglass trench cover plate is made of 8-layer interlaced woven alkali free fiberglass yarn, which is cast and molded. This alkali free glass fiber yarn has high strength, toughness, high temperature resistance, and good resin synthesis. Its fire resistance has passed the flame retardant test of ASTME-84. The price of fiberglass products mostly depends on the price of raw materials, and it is important not to choose medium alkali or high alkali fibers. High alkali fiber: refers to glass components with R20 content higher than 15%, generally synthesized from waste glass. The country has banned the production of such products. Medium alkaline fiber: a glass component with R20 content between 12-15%. Due to its high alkaline content, it cannot act on electrical insulation materials, but its strength and chemical stability are still good. Alkali free fiber: R20 with a content of less than 1% has excellent insulation, strength, and stability, and can be applied to multiple fields.

The functional advantages of fiberglass trench cover plate:
Beautiful appearance: The lines are simple and straightforward. Silver exterior, modern trend.
Good drainage: The leakage area reaches 83.3%, which is more than twice that of cast iron.
Hot dip galvanizing: Strong rust resistance, maintenance free and replacement free.
Anti theft design: The fiberglass cover plate is hinged to the frame for anti-theft, safety, and easy opening.
Save investment: large span. When overloaded, it is cheaper than cast iron and saves the cost of theft or crushing replacement.
High strength: The strength and toughness are much higher than cast iron, and it can be used in environments with large spans and heavy loads such as docks and airports.
