the panels for the door are bonded with an adhesive to hold them in place. the adhesive would probably work if it was properly applied but there are gaps in the adhesive and in some places there is no adhesive at all.
the door relies on the forming of the panels to keep the door flat when raising and lowering the door and if any of the glue gives away, the panel flexes and the panels break.
There could easily be hat shaped reinforcement strips across the width of the door on each panel and these could be screwed in place to keep everything in place even with a rotten glue job. this door is nothing but cheap trash.........
