1) The models, specifications and characteristics of the hardware accessories should be applied to the implementation standards and relevant requirements of China's product implementation, and should be consistent with the choice of plastic steel windows.

2) The production and processing of axis hardware stamping parts should be equipped with a double pulley or rotating pulley with a total width of more than 1 meter, or an assembly of hollow glass.

3) The sliding door hinge cannot use aluminum alloy material, and stainless steel plate should be used.

4) When assembling hardware parts with fixed screws, the metal composite port must be set inside, and the thickness of high -quality hardware processing equipment should be at least twice the distance between the standard parts. Whether it is fixed on the plastic aluminum alloy profile is not important, do not choose non -metal lining.

5) Finally, assemble hardware accessories, and then assemble windows anti -theft locks, door handle, etc. after the fan enters the frame to ensure that the location is appropriate and the total power switch is flexible.

6) Maintenance and maintenance should be performed after assembly of hardware stamping parts to prevent rust and corrosion. In daily use, lightly close and open to prevent damage caused by hard shutdown and hard opening. No noise, now there is a nylon polishing wheel. It not only has no noise when opening the door, but also smoother and softer. The service life is shorter than the various pulleys above. In order to run steadily, we must choose a high -quality pulley. On the surface, the quality of counterfeit and inferior pulleys is uneven and not smooth. Choose flexible small and light.
