1. Visual inspection: Whether the board surface is flat, no scratches or other defects; whether the section is black, gray, green and impurities 2, feel: touch the surface is delicate, whether there is a burr 3, ear listening: good panel with a finger to knock, the sound is crisp, poor voice dull 4, color difference: the same product batch number of the board color is consistent, there is no color difference after splicing installation 5, splicing: check whether the splicing is flat, whether it is kept at the same level, with or without gaps 6. Bending: A panel with toughness can be bent with moderate hand to judge whether the material of the sheet is elastic and whether the weather resistance is good. 6. Although the material of the integrated ceiling gusset is made of aluminum, it is also divided into recycled aluminum, ordinary aluminum and aluminum alloy. Aluminum alloys are also classified into aluminum-magnesium alloys, aluminum-manganese alloys, and aluminum, magnesium, and manganese alloys (aluminum itself is relatively soft, magnesium is added to increase the toughness of the sheet, and manganese is added to increase the rigidity of the sheet). 7. The gusset process is divided into laminated board, roll coated board (matte and bright), and oxide board (single oxidation and multiple oxidation). There are also solid color plates and flower panels (styling plates). 8. The thickness of the gusset plate: 0.6 thick for the family is enough, and the industrial use needs 0.8 thick or more. But definitely not the thicker the better. (Because some merchants use recycled aluminum, only increase the thickness of the aluminum plate to increase the life of the gusset) PVDF as its name implies, it is the use of PVDF as a coating material on the surface of the Aluminum Coil.PVDF is a kind of polyimylidene fluoride material. PVDF material is widly used on aluminum composite panel, Aluminum Sheet,aluminum honeycomb panel,Aluminum Ceiling, roof,pop-top can and electronic products. This material leads to maintenance and anti-corrosion.PVDF coated aluminum is the most popular aluminum product nowadays.

PVDF aluminum coil is level,beautiful,good quality,stability and environmental protection.
Usage of PVDF aluminum products:
Architectural aspect(like window blinds,roll-up door,garage door,rainshed,rain gutter)
Electronics and electronical equipment(like electrical panel,computer cabinet)
Others: solar reflector,blast pipe,furniture and electrical lighting.
