Fiberglass grating, when we hear this name, we must be confused and think that it must be a high-end precision material that ordinary people cannot access and the price is also very high. In fact, it’s quite the opposite. Fiberglass grating is very common in daily life. They can be commonly seen in factories, building facilities, roads, and sports venues, and their prices are also very affordable. Today we will discuss the price and specifications of fiberglass grating cover plates, as well as other related issues, in order to further understand the relationship between fiberglass grating prices and materials.
The two factors that affect the price of fiberglass grating are the type of raw materials used in the production of the grating panel and the specifications and dimensions of the product. The main raw materials for producing fiberglass grating panels include unsaturated polyester resin (including ortho -, meta -, vinyl, phenolic, bisphenol A, etc.), glass fiber rovings (including alkali free, medium alkali, and high alkali types), and filler powders (including aluminum hydroxide, calcium carbonate, etc.). We need to decide which type of raw material to use for production based on the specific application of the product. The performance of grating panels made from different types of raw materials also varies, and the price of the product is also different.

The specifications and dimensions of fiberglass grating panels are another factor that affects product prices. The specifications and dimensions of the grating mainly include the length, width, and height of the product. The height (also known as thickness) of the grating is the main factor affecting its price. Common thickness specifications include 25mm, 30mm, 38mm, 40mm, and 50mm. The thickness of the grating is also a major factor affecting the load-bearing performance of the product.
There are two aspects that need to be mentioned here. On the one hand, as we mentioned earlier, due to differences in raw material prices in different regions, the same product prices may also vary. On the other hand, we need to talk about the difference between national standard products and non-standard products. The so-called national standard grille refers to the fiberglass molded grille that can meet the requirements of national standards. The grid plate produced using molds that comply with national standards is commonly known as the national standard grid.
For example, for a 38mm thick grille, the national standard is that the thickness of the grille plate is 38mm, the upper width is 7mm, the lower width is 5mm, and the number of layers of glass fiber roving reaches 8. So, what kind of product is non-standard grille? Non standard fiberglass grating is a product that has been modified based on the basic dimensions of the national standard grating. Generally, non-standard fiberglass grating will have its width reduced to save some raw materials and lower production costs. Therefore, the price of non-standard grating will be lower, but the quality of the product will also be relatively poor.
In addition, some unscrupulous merchants may reduce the number of layers of glass fiber rovings used in order to seek greater profits. Although there is no obvious difference in appearance, the load-bearing performance and overall stability of the grille panel are definitely much worse than qualified products.
