UPVC Profile is a special product, but it is not impossible to check it. Today LUMEI Profile will introduce how to check the quality problems of UPVC Profile.
1. Look at the window surface
The window frame should be clean, flat and smooth, with no scratches or bruises on the large surface, and no weld 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 of UPVC Profile
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. Single-layer glass should not directly touch the profile. The inner and outer surfaces of 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.
The above is the method to check the quality of UPVC Profile.
