Special attention should be paid to the installation and construction of aluminum alloy doors and windows along the coast

[China Aluminum Network] In the coastal areas, due to the relatively large amount of saline and alkali contained in wind and rain, there are certain parts of the area that have not been desalinated using the national standards. Aluminum alloy doors and windows have serious corrosion problems. Give special attention. In addition to the above procedures, the following procedures should also be strictly followed:

1. The aluminum doors and windows brought into the construction site should be placed in a well-ventilated, dry-bath and clean warehouse.

2. The height of the sleeper surface above the ground should be >=100mm. Each yard should not exceed 15 moulds (fans), and a soft material levelling should be applied between each mould (fan) to prevent pressure damage and aluminum alloy and hardware parts. The mutual friction damages the protective film on the profile surface.

3, door and window openings must have a drip line, should be tested before installation. Because the rainwater flowing through the wall made of sea sand is highly corrosive, it must be guarded against.

4, the installation of iron sheet should adopt the card type, to minimize the destruction of the protective layer of aluminum alloy processing.

5. The aluminum alloy section joint is sealed with a neutral gel to prevent rainwater from entering the inner cavity without a protective layer. As a rule of thumb, corrosion usually begins in the interior without a protective layer.

6, after the completion of interior and exterior decoration. Remove the protective tape and clean the doors and windows. Do not clean the doors and windows with liquids with a high degree of corrosion, as well as hard objects, so as not to damage the surface paint film.

7, important tips:

1) Aluminum is a live metal. The damage of the protective layer is that it has no anti-corrosion ability. It is easy for the flat to take a strong description to apply strong protection to the paint film on the surface of the profile.

2) Water is the source of corrosion. Rainwater should be prevented from entering the interior of aluminum alloy profiles without corrosion protection.
