Square metal pipes are the eighth of 9 different, thin-walled substrates, which are considered under 'Special Facades' in FassadenGrün. On this page, such components are illuminated in more detail, and image examples show which of the eight mounting variants, which are also shown in 'Special Facades', are particularly suitable. The site is designed to help you select the right growth system for your situation, e.g. for balcony greening.
Usually it is about supporting balconies, winter gardens, where there are square tubes or rectangular tubes supports. The profiles are made of painted, galvanized steel, made of aluminum or even stainless steel.
The simplest possibility apart from the eight variants is the direct looping of a quadrangular tube with wire rope, see photo. In further exceptional cases variant 03 (through-hole fastening) is suitable, otherwise almost always variant 01 (direct fastening in the outer shell). For example, wall brackets with metric threads such as WM 10101 can be attached directly, but the wall thickness should be at least half as thick as the thread diameter, i.e. for a holder with M10 thread- 5 mm. The four-edged pipes are drilled on one side and are threaded by means of a cutting drill. This manual tapping requires expertise and craftsmanship, and should be done by a specialist company in case of doubt.
