1. Trench cover plate

Trench cover plate is the most widely used fiberglass cover plate in planning, such as common trench cover plates, trench cover plates, sewer cover plates, and so on. Its function is superior, with the characteristics of light weight and high strength, and high wear resistance. The surface of the fiberglass cover plate will undergo certain anti slip and wear resistance treatment.

2. Cable trench cover plate

Strictly speaking, cable trench cover is also classified as a type of trench cover, but its manufacturing requirements are relatively higher compared to general trench cover. The primary requirement is for its functionality, non-conductivity is the primary condition, and the device has high requirements. It is necessary to meet the specified requirements for sealing.

3. Fiberglass grating cover plate

The application plan of the grille cover plate is smaller compared to the above two, mainly because fiberglass grilles are often used instead, without the need to choose a grille cover plate with an additional manufacturing process. Such as common fiberglass cover plates for water tanks, fiberglass cover plates for walkways, and so on.

Application of fiberglass cover plate:

Fiberglass cover plates are primarily used for laying trenches and walkways, and are commonly used in power plants, sewage treatment plants, and stairwells and walkways.

Fiberglass cover plates have excellent characteristics such as corrosion resistance and flame retardancy, stability and anti slip, light weight, easy installation, maintenance free, and insulation. They have different degrees of superiority compared to traditional materials such as steel, aluminum, stainless steel, and alloy steel. They are suitable for operating routes, stairs, walkways, cover plates, construction and decoration, and have unparalleled effects in fields such as wet heat, easy rust, acid alkali corrosion, and high altitude exposure.

Choose the resin type for the fiberglass cover plate:

There are three commonly used resin types for fiberglass cover plates: ortho benzene type, meta benzene type, and vinyl type. Its price is directly proportional to its corrosion resistance, so the most economical resin type should be selected based on the corrosive medium in the application environment, function introduction, and corrosion resistance function table

A. Ortho benzene type: It has general corrosion resistance function, can withstand atmospheric aging, seawater corrosion, etc., and can be used for a long time at a temperature of -50-60 ℃.

B. Benzene type (for municipal use): It has excellent corrosion resistance and can withstand environments with medium concentrations of inorganic acids, alkalis, various salts, etc. It can be used for a long time at temperatures ranging from -50 to 90 ℃.

C. Vinyl type (for chemical use): It has excellent corrosion resistance and can withstand harsh corrosive environments such as acid, alkali, salt, solvent, or acid-base substitution. It can be used for a long time at temperatures ranging from -50 to 110 ℃.
