First of all, high-quality brushed alumina plates are made of high-quality aluminum materials. At a glance, we will find the difference. High-quality aluminum plates appear to be very firmly adhered and very smooth, while inferior-quality aluminum plates appear to be uneven and often even fluffy. At the same time, we know that the aluminum plate actually has a fireproof function. There is actually a fireproof core board placed in the middle of the aluminum plate. Of course, there will be a big gap in the fireproof core board between high quality and poor quality. After all, many small workshops mainly reduce investment costs by cutting corners and using inferior materials.
