What are the advantages of FRP grating?

The increase of corrosive liquids and gases in life has led to rapid corrosion of metals in these environments. Even if mechanical devices such as anti-corrosion layers are adopted, the corrosion of components is still extremely serious, which not only leads to a bad production environment, but also destroys safe production, and sometimes does not stop production for maintenance.

The polyester grating used as a structural material in these environments can play a very good role. The high quality FRP grating has a series of advantages such as long service life, low cost, safety and reliability, no need for maintenance, and beautiful appearance. In the reconstruction of the Gulf region and the Middle East oil fields, experts have demonstrated that the use of polyester grating is the most economical and reasonable material, so it is being used a lot.

The quality of the raw materials of FRP grating determines the quality of FRP grating. In other words, the composition and raw materials of the glass grating are the decisive factors for the quality of FRP grating. The raw materials used in the production process of FRP grating include resin, glass fiber yarn, curing agent, color paste, etc.

Resin: Unsaturated polyester resin is a thermosetting resin that needs to be used with FRP fiber. When reinforced with glass fiber, it can become a composite material, commonly known as "FRP".

Glass fiber: It is a material used for reinforcement in FRP gratings. There are many types. Its advantages are good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, but its disadvantages are brittleness and poor wear resistance. It is made of glass balls or waste glass as raw materials through high-temperature melting, drawing, winding, weaving and other processes.

Curing agent: Also known as hardener, curing agent or curing agent, it is a type of substance or mixture that promotes or controls the curing reaction. Resin curing is a process in which thermosetting resin undergoes irreversible changes through chemical reactions such as condensation, ring closure, addition or catalysis. Curing is completed by adding curing (cross-linking) agents.

Color paste: A semi-finished product made by dispersing pigments or pigments and fillers in paint. Pure oil as an adhesive is called oily color paste. Resin paint as an adhesive is called resin color paste. The color filler paste dispersed in water as a medium and adding surfactants is called water-based color paste. Because there are many types of paints, there are also many types of color pastes.

So what are the advantages of Fiberglass grating that are favored by more and more people?

1. Corrosion resistance

It has very superior corrosion resistance to many media such as acids, alkalis, organic solvents and salts, and has unparalleled superiority in the field of corrosion protection. Consumers can choose to use orthophthalic, isophthalic or vinyl resin as the base material according to the requirements of the actual use occasion.

2. Lightweight, high strength, and easy to cut and install

Because the tree grate is made of resin and glass fiber, its density is only 1/4 of steel and 2/3 of aluminum. Its strength is 10 times that of rigid polyvinyl chloride, which exceeds the level of aluminum and ordinary steel. Its light weight can greatly reduce the foundation support, thereby reducing the material cost of the project. It is easy to cut and install, without the need for fire and large lifting equipment, only a small amount of manpower and electric tools are required, and the installation cost is greatly reduced.

3. Aging resistance

Theoretically, its service life is more than 50 years

4. Flame retardant

The flame propagation rate of ordinary flame retardant grilles (ASTM E-84) does not exceed 25; the flame propagation rate of advanced flame retardant vinyl grilles does not exceed 10. The oxygen index is not less than 28 (GB 8924).

5. Safety

It has excellent electrical insulation, no breakdown under 10KV voltage; no electromagnetic properties, can be used on magnetically sensitive equipment; the special structure of FRP grilles also has anti-slip, anti-fatigue and other characteristics

6. Uniform color inside and outside

The color can be selected arbitrarily, and the color can be customized according to customer requirements, thereby improving the environment of the production site.

7. It has good comprehensive economic benefits

8. Strong designability: flexible and diverse sizes, stable sizes.
