Color metal tile is a new generation of environmentally friendly chemical building materials, it has won more and more attention and recognition in the construction industry with unique performance advantages. Color metal tile in line with the future development direction of building materials, has a tremendous market potential.
At present, the domestic market continue to emerge many shoddy imitation stone coated metal roofing tile products, in order to more consumers to have a correct understanding and choice of colorful metal tile, for the following recognition and colorful metal tile:
One: look at the appearance
Pick up the stone tile samples, see samples of fault density, particle size and composition. High density, quality and weight (color metal tile light, is not particularly heavy, this point to grasp) that is good color metal tile, and look at the surface of the work is a normal luster. The raw material is the most important color stone metal tile composed of three categories, sand, plate and glue. Look at the size of sand particles is uniform, there is no sand off phenomenon obviously, our factory is using steel plate galvanized steel, snow coating on the back of the green, it is added to the zinc layer.
Color metal tile GB specification is 1345*420mm, the weight of 2.7 kg, the thickness of the steel plate is 0.4, according to the specific custom.
Third: boil with water
With the boiling water boil for one day and one night, to see whether there is sand fade if the stain is sand, the cook for several hours, the phenomenon of fading is obviously, and the sintering sand but not this situation. Some tiles dyed sand rain is brighter, because the general poor sand water seepage, will eventually lead to sand color fade.
