Environmental aluminum square profiles through brand Spot First, the material. Aluminum on the market are the following: the origin divided by aluminum ordinary aluminum, wide aluminum, SWA; in accordance with international labels such as aluminum is divided into 1100,3003,5005 label; Alloy aluminum strength into H24, H18, etc.; according to the toughness of aluminum into ordinary aluminum, magnesium alloy, aluminum-manganese alloy. Most ceiling materials on the market are the ordinary aluminum, which is characterized by low intensity, the general flatness, toughness, not deformed. Without a good base, will greatly affect the aluminum side through life. Second, the surface treatment. Surface treatment of aluminum through the main square are the following: spray, paint, roller, lamination. Covered plate can be divided into ordinary film with imported film, the life of the film basically imports reached 20 years does not change color. Third, the process. Process is the so-called pressure-sensitive adhesive sheet has a surface layer, which is ignored by a consumer comparison. If the process is not good to affect the life of the product is very large, aluminum side through the factory processing technology on the market are very different, a lot of small plants basically take workshops, reducing the process life. When the recommended aluminum side through choice, we must understand clearly this one. 5, install a program, according to the same level as the height of installed aluminum repair the corners 2, according to the appropriate spacing and light steel keel lifting good boom, boom spacing is less than or equal to 1.2 meters, light steel keel spacing is 1.2 m 3, the preinstalled on the triangle keel keel hanging pieces, together with the metal frame triangle perpendicular direction by the plate spacing is connected, and then adjust the level 4, the two sides parallel side plates pressed into triangular keel cracks, transverse direction after the first load Pull the two ends of a straight line after looking at right angles to the side plate gradually withhold rows, each time you want to adjust after breasted ensure board formation, vertical seams. (Note that a square plate with a side bet pits direction is inserted into the triangular keel seam) 5, to wear gloves when pinch, such as accidentally leaving India to use dirty water on the plate clean, tear prohibit the installation protective film.
