Fiberglass extruded profiles are a widely used product in the current market. Their manufacturing principles are significantly different from traditional raw materials, and they also have advantages that traditional raw materials do not have. Their application is also better than traditional raw materials. So, how do we distinguish them? Next, let's take a look together.

We can use quality discrimination methods to distinguish the quality of fiberglass extruded profiles.

Firstly, distinguish from appearance. The appearance of defective products is not lubricated, and their strength and talent are very poor, which cannot be used for a long time. The defective fiberglass extruded profiles are manufactured using defective resin for processing. If a high-quality fiberglass extruded profile splits, it will appear as if bamboo has cracked, while defective ones will appear as if chalk has cracked.

Then, it can also be judged from the color of the product. High quality fiberglass extruded profiles do not contain many impurities inside, while defective products have a lot of impurities inside due to their dirtiness. The quality of glass extruded profiles with many black spots cannot be guaranteed.

In the end, we can see if there are any gaps in its cross-section, which are caused by uneven pulling and squeezing force. The machines used for defective products are not very professional, and this situation often occurs.

So when we choose fiberglass extruded profiles, we must be careful and distinguish high-quality products for purchase.
