What is the quality of rock wool sandwich panels?
Rock Wool Sandwich Panel are often used in Steel Structure Workshop and Steel Structure Warehouse. If you want to purchase a suitable rock wool Sandwich Panel, you must pay attention to its specific quality. Before general wholesale purchases, we need to compare the actual products, so that we can determine whether the specific quality can meet the requirements of use, and then go to wholesale purchases to avoid quality problems. So how to look at the quality of the sandwich panel?

Substrate thickness
When purchasing a sandwich panel, you must first look at the thickness of its base material, and it must meet the corresponding national standards. The thickness of a better sandwich panel will be relatively larger, which can also ensure its quality and service life.

Coating thickness
The surface of the rock wool sandwich panel is also coated, so we must pay attention to the thickness of the coating. The thickness of the galvanized coating of a better sandwich panel is uniform, and it is also hot-dip galvanized, which can effectively prolong its service life, and its anti-corrosion effect is also better than other types of plates.

cross section
If you want to determine the quality of the sandwich panel, you can actually compare it from the cross-section of the edge. Take a look at the exposed surface to see if it is fine and clean, whether it is dark, off-white, and so on. If there are more impurities, it must also prove that its quality is average. But if the crystallization is good and there are no impurities, it also proves that the overall quality of the sandwich panel is good.

Tap to hear the sound
You can simply tap the rock wool sandwich panel to judge its pros and cons. If the knocking sound has a metallic sound and is relatively brittle, then the quality of the plate is also good. But if there is a very dull sound when tapping, and the metal sound is not obvious, then its quality must be relatively poor.

After-sales service
In fact, in most cases, we purchase rock wool sandwich panels in large quantities. In order to enjoy high cost-effective quotations, it is more appropriate to cooperate with manufacturers. Similarly, we should also pay attention to whether a good manufacturer has after-sales service. If the after-sales service is in place, it also proves that the quality of its sandwich panels is good.
