Hello
Today I purchased an aluminum patio roof, which is still assembled at the seller’s site.
Since we need to mount the wall rail higher for attachment, the two front posts are now too short.
I need advice on how to extend them.

I have attached a photo.
We need an extension of about 30–40 cm (12–16 inches) per post (2 pieces).
Currently, the front posts are 2.05 meters (6 ft 9 in), which is too short.

I would appreciate any tips to find a solution.

Buying new posts would be the absolute last option.
An extension would not affect the appearance, as there will be flower pots in front.

A base under the post solves your problem

If you want it to turn out well, it requires some effort. Buying two new posts is probably almost cheaper.

Get an aluminum profile of the same thickness, have it cleanly welded and ground down. Before that, it’s best to insert a square metal tube for reinforcement/stiffening. Afterwards, have the entire post powder coated again.
Find someone who has experience welding aluminum.

It doesn’t have to - he did write that there are flower pots placed in front. So it mainly needs to be cheap, meaning just putting a base under each one should be fine. Possibly even directly inside a flower pot – some acquaintances did that (similar issue), and it looks quite acceptable.

Thank you for the responses.
Since we have dismantled our previous metal pavilion (which was also expensive but had no wall mounting), we now have the solid posts left over.
These are 1 cm (0.4 inches) narrower in width than the newly acquired ones.
So, we will now slide the old posts into the new ones and essentially bolt them together crosswise with threaded rods at the overlapping section at the correct height.
The weight will not rest only on the two front posts but, in addition to the wall mounting, will also be supported by one at the back.

Since our exterior wall is insulated (10 cm (4 inches) plus plaster), we now need to buy the right screws and wall plugs for mounting to the wall.

I would appreciate any tips.
