In fact, to distinguish the quality of a product, the first step is to judge it from its appearance and color, and then from the use of raw materials.
1、 The appearance level, smoothness, and beautiful color of fiberglass grating are the first conditions that need to be met.
2、 Raw materials: Many consumers are not familiar with the raw materials used for fiberglass grilles. The main raw materials for fiberglass grating are resin and fiberglass. The filler is calcium powder, usually at a ratio of 1:1:1. Good resins, such as unsaturated ortho benzene resins 196, 191, and 3301, are generally used to produce smooth fiberglass grilles. If inferior resin is used, the product will appear dull, porous, and most importantly, prone to fracture, with poor strength and toughness, and a relatively short service life.
