6 quality problems to be noticed
6.1 warping and channeling angle: steel Windows and doors processing individual fans are there standards of quality: carefully in case of transport stack, not seriously kept; vertical flat installed enough, should be carefully checked before installation, find warping and angles should be corrected in a timely manner to repair, fix after installation.
6.2 iron fixed foot does not meet the requirements: original foot position for reserved holes and iron, and has no checking and handling before installation, during installation any gas welding burning iron feet, some iron foot bending cram into holes in the severely affected steel Windows installation firm.
6.3 steel doors and Windows are not straight up and down, steel doors and Windows around the elevation is not consistent: no process construction points, before the construction could not find the rules, no thread during installation.
6.4 steel door and window switches are not flexible: eat affect their flexibility when plastering; install vertical founder did not find a good, door and window splitting, channeling angle angled or after repair. Request check switch test was carried out after the installation of steel doors and Windows, is flexible, the effect switches the plaster layer should tick up again, door and window fans split ribs and shot angle should be adjusted.
6.5 opening direction is not in place: plastering quarrel not founder, or arch face drooping, convex lines are not straight, will directly influence the opening of doors and Windows. When plaster is required strictly according to the evaluation standards inspection, after the failed to fix, then woodworking installing doors and Windows.
6.6 the adjustment of steel doors and Windows, or processing such as welding, gas cutting and uncertain to solder coating does not hit, welding without steel fell file, don't brush paint.
6.7 steel Windows with water; when installing Windows, use errors, steel Windows keep. Should carefully check the window number, meets the requirements before installation, and pay attention to the protection of the pishui when stacked.
6.8 metal parts wood is complete and comprehensive, construction lost, second supplement and does not match the original brands. Request entry of steel and metal fittings at the same time supporting the processing and consider reasonable failure rate, processing orders at a time enough.
6.8 fans stretch yarn made of rough, hard waste exposed: gauze window sash and door does not fit on the CD, the aperture is too large, yarn tightly, or yarn head exposed.
6.9 press yarn using the self-tapping screws too long, sharp exposed easily hurt.
6.10 steel screen doors and Windows painted rough, or paint the exposed grass-roots dirt cleaned is not clean.
