Support studs are fixed to outer skin of the base structure from both flanges with overlap screws (‘Screw S1H48023L02A4’) c/c 250 mm. Studs with only one flange (e.g. CA1RS1) are fixed c/c 125 mm.If base structure flatness can’t be ensured, i.e. panels are not forming even surface (e.g. due to tolerances in load bearing frames) to cladding material, adjustable Ruukki studs have to be used. Adjustable Ruukki studs can accommo- date up to 30 mm tolerances.Starting filletsIn Lamellas groove 10 and 20, sharp 45, lap 60, and straight 100 a separate starting fillet is needed.
