When we choose commodity, one of the most commonly used points is to look at it. The same is true for aluminum-plastic panels. The main points are:
- Leveling: See if the surface of the aluminum-plastic panel is smooth and smooth
- Ripple: See if the surface has ripples
- Bubbling: See if there is bubbling on the surface of the board
- Pleasure Point: See if there is a shelter
- Scratches: Look at the surface for scratches
When looking , be careful to choose a really good aluminum composite panel.
