Choosing thickness and coil width for writing steel
Width should be chosen for least trim waste against your finished panel size, not for the widest coil available.
Coil width runs from 600 mm to 1500 mm. The right width is the one that divides into your finished panel size with the least trim, which is often not the widest coil we can supply. A wider coil that leaves a 200 mm offcut on every panel is more expensive per usable square metre than a narrower one that nests cleanly.
Thickness is a rigidity and magnetics decision. Thin substrate saves material and gives a board that oil-cans when written on; thicker substrate is flatter and holds magnets better but costs more and weighs more to ship.
Tell us the finished panel size and we will advise the width, rather than quoting the widest coil and letting the trim waste become your problem.
