FRP gratings are used in many places, such as operating platforms, Stair Thread ,walkways, floors, trench covers, pedestrian bridges, equipment safety bars etc. Now, the FRP grating market in China is very hot, there is a big difference in quality level from different supplier . In order to reduce the production cost, many manufacturers choose some raw materials with relatively poor residuals to make them shoddy. However, as a customer, they don’t know the nuances in it. Today, Hebei QiQian came to talk to clients about how to distinguish the quality level of FRP grating.
First of all, when we judge the quality of a product, we must first judge the quality of its raw materials, and then judge the product.
1)Raw materials
Regarding the selection of raw materials for FRP gratings, many customers are not clear. The main raw materials of steel gratings are resin and fiber. The filler in between is calcium powder, and it is generally equipped with a ratio of about 1:1:1. A good resin is generally unsaturated ortho-phthalic resin 196. The FRP grille produced by using this resin is generally flat and smooth. If the inferior resin is used, the product will be more dirty, porous, and the main reason is simple cracking. , The strength is poor and the toughness is not good.
2)Appearance
Another thing is the comparison of products: from the appearance of a good FRP grille, there are no obvious cracks, pores and sand table, the color is relatively pure, and the service life is relatively long. However, the defective product has obvious cracks in appearance, many pores, poor color, and very short life.
3) Listen to the sound of FRP grating
The third is to listen to the sound: tap the edge of the FRP grille and listen to the sound. If the sound is crisp, it is a qualified product, and if the sound is dull, the quality is average.
The above are 3 simple judgment methods recommended by Hebei QiQian for you. I hope it will help you to buy FRP grating products in the future.
