Bi-fold Door Quality Control
We believe that the best way to make sure that every single one of our Bi-fold doors arrives to you in an excellent working condition, is to check them thoroughly before they leave the factory. Each Bi-fold door therefore that leaves the factory is checked by the Quality Control area and some of the checks are detailed below.

1. Firstly we mount the bifold door on a purpose-made jig. The doors are checked for square, then each of the panels are checked for tolerances and correct operation |

2. The dimensions are checked against the manufacturing details, then the gaps between each panel are checked. It is essential that the gaps are 11mm to prevent the door leafs binding. |

3. All the mitre cuts are surveyed to ensure they are clean and smooth. Poor mitres are noticable and may allow water ingress. |

Once the doors have been checked and compared to the worksheet (shown in pic on left) it gets a green "PASS" stamp and is signed off by quality control. |
Now that this door has passed quality control it will be wrapped up in several layers of bubble wrap and packing tape ready for delivery to our customer.
