Hello,
I ordered a 6x3m (20x10 ft) aluminum frame canopy with glass from the Netherlands.
To save costs, I will have to do the installation myself.
According to the delivery list, I will receive 12 stainless steel wire bolts, 8 x 60mm (0.3 x 2.4 inches).
I have a cavity wall (see picture).
My colleague warns me not to use those for fastening.
He mentioned something about threaded rods or chemical anchors.
Could someone please give me advice on how to properly and cost-effectively fix the wall profile to the wall?
I have no idea about the right length, thickness, etc.
Best regards from Hörstel

It looks like your roof comes from Eindhofen. I’m interested in that as well. My neighbor has the same one.
He didn’t use wire nails but rather anchor bolts with plugs. I also briefly considered that.
My wall construction is as follows: 11.5 cm (4.5 inches) solid clinker brick, 14 cm (5.5 inches) insulation (mineral wool) with an air cavity, 17.5 cm (7 inches) Poroton brick (hollow clay brick).
I contacted the mentioned manufacturer/supplier to ask whether a mounting method other than wire nails (fastening in the rear masonry) using injection is possible, or if another mounting option is available for cavity walls. Here is their reply:
Our engineers always install the wall profile and wall with less than 10 centimeters (4 inches) of insulation.
For walls with more insulation or insufficient strength, we recommend a construction beam.
-> The construction beam is basically a post and a support beam on the house wall, but not connected to it. This is not an option for me.
Currently, I am leaning toward fastening with threaded rods and injection mortar. I just haven’t decided on the number of rods or diameter yet to comply with snow load requirements. I think 10 rods (my wall width is 8 meters (26 feet)), so one every 80 cm (32 inches), should be sufficient.
My explanation might not help you much, but maybe at least their statement regarding the fastening method will.
Best regards

Trasher1911 Jul 2019 13:0780 kg/m2 (16.4 psf) snow load? Where is this going to be built? I live here in the Allgäu region (probably not comparable), but currently we have snow loads of 300 kg/m2 (61.4 psf).
