Coastal areas due to the amount of salt contained in the wind and rain is relatively large, there are some areas where the use of national standards are strictly prohibited without desalination of the treated sea sand, aluminum alloy doors and windows corrosion problem is more serious, should be given special attention. In addition to the above procedures, the following procedures should be strictly followed: 1. Aluminum doors and windows transported to the site should be placed in a well-ventilated, dry bath and clean warehouse. 2, the placement of the sleeper surface height from the ground should be> = 100mm, each yard pile shall not exceed 15 mold (fan), each mold (fan) between the application of soft material pad flat, in order to prevent crushing and aluminum alloy, hardware friction between the damage profile surface protective film. 3. The door and window openings must have drip lines, which should be inspected before installation. Because the rainwater flowing through the walls made of sea sand is very corrosive and must be guarded against. 4. The installation of iron sheet should adopt the card type to minimize the processing amount of damage to the aluminum alloy protective layer. 5. The joint of aluminum alloy profile shall be sealed with neutral glue to prevent rainwater from entering the inner cavity without protective layer. As a rule of thumb, corrosion usually starts from an inner cavity without a protective layer. 6. After the interior and exterior decoration is completed. Remove the protective tape and clean the doors and windows. Do not use corrosive liquids and hard objects to clean the doors and windows to avoid damage to the surface paint film. 7. Important Reminder: 1) Aluminum is a lively metal, and the damaged part of the protective layer has no anti-corrosion ability. It is easy to form flat groups. Proper tracing should be taken to strengthen the protection of the paint film on the surface of the profile. 2) Water is the source of corrosion, and rainwater should be prevented from entering the inner cavity of aluminum alloy profiles without anti-corrosion ability.

2. The height of the sleeper surface at the place where it is placed from the ground shall be> = 100mm, and each yard pile shall not exceed 15 molds (fans). Soft materials shall be applied to level each mold (fan) to prevent crushing injury and mutual friction between aluminum alloy and hardware from damaging the protective film on the surface of the profile.

7. Important Note:
1) Aluminum is an active metal, and there is no anti-corrosion ability at the damaged part of the protective layer. It is easy to cause flat groups. Proper tracing should be taken to strengthen the protection of the paint film on the surface of the profile.
2) Water is the source of corrosion, and rainwater should be prevented from entering the inner cavity of aluminum alloy profiles without anti-corrosion ability.
