Aluminum alloy buckle plate is divided into two kinds of sound-absorbing board and decorative board, sound-absorbing board floor are mostly white or aluminum color; decorative board focus on decorative, there are bronze, gold, red, blue, milky white and other colors can choose.
So, how to identify the advantages and disadvantages of the aluminum alloy pinch it?
1. Substrate: Take two different aluminum buckles, tap the substrate, listen carefully, the sound is brittle, the substrate is good, and the sound is boring.
2, the surface: to find a short sample, repeated abortion, to see if it paint off, peeling. A good aluminum plate paint only cracks, there will be no bulk paint off; In addition, a good aluminum buckle plate is painted on the back;
3, keel: keel must meet the standard thickness, must be straight; keel material is generally galvanized steel, mainly to see its flatness, the smoothness of the processing; view the brochure marked on the keel accuracy, the smaller the error range, The higher the precision, the better the quality.
