How to check the quality problems of uPVC Profile

uPVC Profile is a special product, but it is not impossible to check it. Today Jinan lumeiuPVC Profile will introduce how to check the quality problems of plastic steel profiles.

1. Look at the window surface

The window frame should be clean, flat and smooth, no scratches or bruises on the large surface, and no open welding fracture on the profile.

2. Look at hardware

The hardware must be complete, in the correct position, firmly installed, flexible in use, and able to achieve their respective functions.

3. Look at the glass sealing strip

The contact between the sealing strip and the glass and the glass notch should be smooth, and no crimping or de-troughing is allowed.

4. Look at the sealing quality

When the doors and windows are closed, there is no obvious gap between the fan and the frame, and the seal on the sealing surface should be in a compressed state.

5. Look at the glass

The glass should be flat and firmly installed, and there should be no looseness. The single-layer glass should not directly touch the profile. The inner and outer surfaces of the double-layer glass should be clean. There should be no dust and moisture in the glass interlayer, and the partitions should not be tilted.

6. Look at the layering

The bead with sealing strip must be tightly attached to the glass, there should be no obvious gap between the bead and the profile, and the joint gap should be less than or equal to 1 mm.

7. Look at the spelling material

The assembling material should be tightly connected with the window frame and sealed with caulking paste. The screw pitch should be less than or equal to 600 mm. Both ends of the lining reinforced steel should be firmly fixed to the opening.

8. Look at the switch parts

Flat opening, sliding or rotating windows should be closed tightly.

9. Look at the frame and the wall

The window frame should be horizontal and vertical, and the height should be the same. The distance between the fixed pieces should be less than or equal to 600mm. The frame and the wall should be firmly connected. The gap should be filled with elastic material and the surface should be sealed with caulking paste without cracks.
