Construction quality records

In order to ensure that the project quality meets the standard, it is necessary to keep quality records in the project construction, mainly considering the inspection items related to safety and function:

The wind pressure resistance, air permeability and rainwater permeability of metal windows on the external walls of buildings.

Check the product certificate, performance test report, mobilization acceptance record and re inspection report, and check the acceptance record of concealed works.

Finished product quality inspection

1. Main control items

(1) The variety, type, specification, performance, opening direction, installation position, connection mode and profile wall thickness of aluminum and gold windows shall meet the design requirements. The anti-corrosion treatment, caulking and sealing treatment of aluminum alloy windows shall meet the design requirements.

(2) Aluminum alloy windows must be installed firmly, and should be opened and closed flexibly and tightly without inverted wings.

(3) The model, specification and quantity of aluminum alloy window accessories should meet the design requirements, the installation should be firm, the position should be correct, and the function should meet the design requirements.

5. Before caulking the joints of aluminum alloy windows, the contact surface with cement mortar shall be painted with preservatives for anti-corrosion treatment.

6. Before plastering, the aluminum alloy sliding window shall be protected with plastic film. Before the indoor wet operation is completed, no type of work shall damage its protective film to prevent the erosion of mortar on its surface.

7. The protective film of aluminum alloy window should be removed before handover, and it should be gently removed, and it is not allowed to use a knife shovel to prevent scratching the surface and affecting the appearance.

8. If there is glue on the surface of aluminum alloy window, wipe it with cotton wool dipped with special solvent. If local scratches are found, use a small brush dipped with dye to coat the beam.
