The raw materials used for fiberglass grilles are resin, fiberglass fibers, and calcium powder filled in a ratio of 1:1:1. High quality fiberglass grilles are made of high-quality resin: unsaturated ortho benzene resin 196, colorless and transparent. Low viscosity, low heat release, low shrinkage, high-speed curing, high-speed compatibility, and bright glossiness. The produced fiberglass grating is flat and smooth, with good glossiness, high strength, and a certain degree of toughness. If inferior resin is used, it will be completely opposite. Inferior resin is turbid, high viscosity, high heat release, high shrinkage, relatively slow curing, and poor compatibility. The produced fiberglass grating has many pores, is easy to break, and has poor strength and toughness.

Fiberglass fibers can enhance the toughness of fiberglass grilles. High quality fiberglass fibers, such as alkali free fiberglass fibers, have higher strength than steel wires and have a certain degree of toughness, chemical stability, good weather resistance, almost no water absorption and no combustion when exposed to fire. Their high strength can also be used as tire cord.

The filling material for fiberglass grating is calcium powder or aluminum powder. High quality filling material has a fine and clean white powder, flame retardancy, and is completely fused with resin. The produced board has a beautiful color, good transparency, and high toughness. On the contrary, low-quality fillers have a rough and dull powder, are not flame retardant, and produce boards without luster, which are relatively brittle and lack toughness.

High quality fiberglass grating products have no obvious cracks in appearance, fewer pores, bright and pure colors, good transparency, certain toughness and strength, good surface smoothness, and long service life; However, low-quality fiberglass grating products have cracks on the appearance, many pores, impure color, and insufficient glossiness. Its service life is also relatively short.

Although fiberglass grating cannot completely replace steel grating, it completely compensates for the conditions or fields that steel grating cannot meet. It fully reduces the non capacity burden of steel grating and also provides people with another solution to the problem. Its appearance has become a powerful supplement to steel grating.
