What are the standard tolerances for aluminium extrusion profiles?

According to EN 12020-2, standard tolerances are: wall thickness ±0.15mm for ≤3mm, ±0.20mm for 3-6mm. Length tolerance is +5/-0mm for lengths up to 6m.

What profile lengths does GBS Aluminium supply?

Standard lengths are 3m, 4m, 5m and 6m. Custom-cut lengths are available with precision sawing (±0.5mm tolerance). Maximum extrusion length is 7m.

What is the difference between EN 755 and EN 12020 standards?

EN 755 covers general extrusion profiles (bars, tubes, angle profiles), while EN 12020 specifically applies to precision profiles with tighter tolerances, especially for window and door systems.
