How to distinguish quality of aluminum?
Third, compare the front cover Lvkou film
Identification of surface coating method is to look at the quality of the edge of the aluminum buckle, see if I can expose the film together. Eligible Lvkou film at a high temperature composite up, exposing not down, can be peeled off the adhesive certainly can not be purchased. Also a lot of sales will be known as their Lvkou Ban imports of coated film, in fact, once the difference between the so-called Lvkou film imports and domestic film installed fundamental rarely move, and hanging in the roof, there is unlikely to see out . So completely did not need to care about the film is not imported, just to get a few sample compare to light, choose a good gloss on it.
Second, the comparison Lvkou primer
Protective effect of the primer will not produce steam when Lvkou kitchen or bathroom everyday life from every penetrate to the bottom of the gusset plate connecting gusset, pinch bottom surface of the ceiling to make long-term and a long water, air contact time will be from Lvkou rusty moldy until the bottom started to lose effect. Integrated ceiling Lvkou high quality primer should be evenly sprayed on the bottom plate, the specifics of how evenly to carefully observe the eye when the board at the end, will not find there is not a small point silver (aluminum-magnesium aluminum plate itself is its own silver) prevail.
First, more flexibility and strength of aluminum buckle
Identification method is very simple: take a piece of aluminum buckle, folded his hands, bad Lvkou can easily be bent and will not restore its original shape, and good Lvkou you need to bend spend some effort, and after bending, to a certain extent on the rebound, this is the difference between toughness and strength of aluminum. After installation will not be a good situation Lvkou bend or fall down the middle, to ensure smooth.
