The direct identification method for the appearance of fiberglass cover plate products. If the surface of the fiberglass cover plate product is smooth, with few pores, no cracks, and no detachment, then the product quality is good; On the contrary, if the surface of the product is rough, peeled off, has many cracks, and has many pores, the quality is poor. The appearance of high-quality fiberglass cover plates exhibits the following characteristics: the surface of high-quality fiberglass cover plates is smoother, smoother, and feels better; High quality grille covers do not have a strong odor, but have a faint varnish smell; If there are slight bubbles in the fiberglass cover plate, it indicates that high-quality resin has been selected. Due to the high density of good resin, there will be fewer bubbles.

Through the load-bearing test of physical products: This is a more intuitive way to conduct load tests on the grille on site, observe its deformation, and observe its load-bearing performance. Knocking the outer wall of the fiberglass board clearly indicates the use of a large amount of resin. Conversely, if the knocking sound is low, it indicates the use of less resin and more calcium powder, indicating poor quality.

The advantage of grating is its weight and strength: its strength is ten times that of PVC, and its absolute strength exceeds that of ordinary steel. Corrosion resistance: Polyester is a non-metallic material that will not mold, rot, or be corroded by coatings, gases, and liquid media. Therefore, it does not require maintenance or use under more ordinary metal grids. It is resistant to chemical corrosion and rust, and does not require regular inspection and maintenance. Labor resistance: The fiberglass grille has a certain degree of elasticity, which can make users feel comfortable when working on it. At the same time, the fiberglass cover can also reduce the fatigue of the legs and back of the workers, increase the comfort of work, and improve work efficiency. Easy to install: Made of polyester mesh, it can significantly reduce the weight of members and brackets. No lifting tools are required during installation, saving construction convenience.
