The main consumption area of color-coated plates in China is still the construction industry, accounting for 85%-90% of the total consumption. From the perspective of the construction market, the use of steel plates in China's construction sector has been steadily increasing, and the proportion of color-coated plates in construction steel plate usage has also been rising year by year.

Because color-coated sheets undergo strict control in every manufacturing process, ensuring uniform quality in terms of appearance, durability, and workability.

During the welding of color-coated plates, air bubbles may sometimes appear due to external factors. This phenomenon can lead to weak welds and affect aesthetic quality. Therefore, we should try to avoid such situations during welding. So what causes this phenomenon? Only by identifying the root cause can we better resolve it. Below is an explanation for everyone.
